    They can release the whole source for their linux OS. The playstation and playstation 2 have copywrite protection that searches for "bad" areas of the disc, know as the boot sector. Domestic CD-RW drives cannot perfectly duplicate these discs, so you have to "modify" your console to get it to boot these discs. Sony has recently been going after the makers of the devices that allow you to boot CD-R's and DVD-R's. So, most people, even with the PS2 linux source, couldn't use it without buying Sony's disc. They could also make it so big that you can't fit it on a 700MB disc, being a DVD release only, which would further prevent most from getting it for free.

      A couble of comments:

      1) Its actually not "bad areas" that Sony is using with PS2 discs. They have encoded a sort of sub-signal onto the disc that bruners cannot recreate and more important, nor can asian "copy shops".

      2) The PS1 discs has a error written into the TOC but CloneCD (aand others) deals with this without problems.

      3) Developers can actually buy CDR's at Sony with the copyprotection on, so they can burn discs to test on non development equipment.

      4) Sonys DVD-ROM's has the same copyprotection buildin as the CD's. So even with a DVD-R (Burned on the A03) you cannot boot with a modchip.

I thought that it *had* to be done by a normal cd press (or whatever they use to mass produce cds) and not something you could put on a cdr (from what I know its different then a cd, the chemicals/metals used in the disk).

        I don't know where you've been getting your information, but it is very possible to boot DVD-R discs in a modded PS2, however the technique is just a little awkward with the currently modchips (a double swap is required). I used to own an A03 (until the thing died and the shop had no stock to replace it - ugh!), and I've tried a few copies on my unit, they work fine.

        I don't see why I couldn't just concoct a PS2Linux-based DVD-R with custom software, it should be fairly trivial.

    In order to get Linux running on your PS2, you must boot the system using the PS2 Linux DVD. During boot, after all the copy-protection stuff is taken care of, the system lays down the Runtime Environment. This is basically a layer that hides access to the SPU2 (Sound Processing Unit), the input/output processor, the hard drive, the CD/DVD-ROM system, the controllers, memory cards, USB, i.Link and other peripherals.
    I doubt it'll be long before there's a work-around. Placing such limitations on a piece of hardware or software never works.

    See: CSS, DVD regioning, Windows XP Product Activation, PS2 Copy Protection, eBook encryption, et al.

    When will big business learn? If something is secured in a paranoid way, it will be overcome to a degree. The prize is too big.

      "I doubt it'll be long before there's a work-around."

      Yes, but it's worth considering how involved the work-around is. For example, in the realm of books, the copy-protection work-around involves the rather tedious task of either manually retyping the entire book or using a scanner and OCR software. It's doable, but it's certainly not easy.

      Likewise, if the PS2 work-around is inconvenient enough (such as the traditional mod-chip solution, which requires playing around with solder and several hundred dollars worth of easily broken Playstation internal hardware), it's going to reduce the number of people that use it. Compare this to the Dreamcast, where the copy protection was (as I understand it) completely defeatable on the software level -- you just had to download games cracked by other people, and you were set. The only requirements were having broadband and a CD burner (or a nearby friend with the same).

      Anyway, I suspect one of the reasons behind Sony's goofy intermediate device driver system is to keep the Linux kit from turning into a easy, modchip-free copy protection breaker. Without their (admittedly annoying) protection system in place, I could see the PS2 Linux system being used as a giant bootloader to get the PS2 to read and execute a burned game. There would still be other software hurdles to overcome (such as any in-game copy protection checks and chopping things down to fit on a CD), but those're the same purely software hurdles that're already regularly tackled by cracking groups.

      In short, even though I don't like the protection mechanisms Sony's introduced, I can understand why they did it.

    • I like the idea of porting Linux to my Dreamcast because it gives it new life. For example, I want to be able to burn CD's of DIVX-compressed movies and play them back on my Dreamcast, so I can watch them on my TV w/o need of having a computer attached.

      If first they port Linux to the DC (which I think has been done...), then they port DivX to the DC, then those are the building blocks I need to do this. Then, they can port Linux to the PS2, and then this code at some point will be able to run on it. Suddenly my extinct game machine has a new purpose.

      If anything, it's a fun project. Practicality comes later.

        • Heh I said Dreamcast, not PS2. If I were to buy a PS2 for that purpose, by the time it gets cheap enough I'll have a DVD burner. My understanding is that it won't be long before I can get a DVD burner that makes DVD's playable on a DVD player. I'll probably want to use DivX at that point since I can stuff a lot more onto a DVD than I could with MPEG2.

          It's hard to predict what other uses I'll find for it, though. I like the idea of playing MAME on my Dreamcast. It'll likely run better on the PS2, though.

          Once Linux is sucessfully ported to PS2 and easy to burn discs for, then the life of the PS2 is extended for me. When they start bombing them out for $50 - $100, then I'll be able to do something with it after the games get old.
      • There is a port of DIVX to the DC, it is not optimized and is unable to play movies @ full speed. Maybe if someone is willing to profile and convert it to ASM it will be fast enough to play movies.

        With all these propertiary consoles it's tough to spend a lot of time programming them since so much has to be thrown away when going from one console to the other. At least C is kinda portable.

    Personally I have had bad experiences with Sony. I have had 4 PS1's and 1 PS2, and a multitude of other Sony products. While typically for the most part the products are good the one thing that gets me about Sony is Warranty and support. Even the most minor thing is a instant void of warranty. I watched them void a friend of mines warranty on his PS2 becuase his fiber audio out cable wasnt made by Sony. I've also seen them do the same thing for the composite cable on the way out, and even power cables on the PS1. Not to mention non Sony memory cards, yes and even games. Which brings me to my point. If using anything non-Sony voids a warranty.... What happens if you add anything at all to the Linux distro they provide you with. Does that void your warranty? Or are they making exceptions in thier policy this time. I'm willing to bet they aren't making any exceptions.

        A Sony car stereo that I bought a couple of years ago conked out after a few months. It was purchased as new old stock and I had a receipt for it (it was an older shaft-type unit with a reasonably decent feature set...you try to find something better than a $20 parts-store radio that'll fit a '77 Olds without hacking the dash to bits). I took it to a local repair shop for what I figured would be an in-warranty repair. To make a long story short, even with the dated receipt, Sony wouldn't honor its own warranty.

        I won't be buying other Sony PDAs in the future.

        If I were you, I wouldn't buy anything Sony. They might've made decent stuff in the past (my dad has an open-reel tape deck that's almost as old as I am that still works AFAIK), but Sony seems to be more about image and style than functionality or making a product that'll hold up to at least normal use.

        • I made some other comments about Sony and quality just recently, in another Slashdot thread -- but I'll say it again here.

          Sony makes so many different electronics products, it's really hard to avoid them completely. They have a few poor products out there (their portable CD Discman players come immediately to mind), but at any given time, they also make some really good stuff. Every review I've seen rates their camcorders as the best value on the market. (Canon usually comes in a close second.) The rule of thumb for their car audio has been "only buy the ES stuff, or else it'll be junk". 90% of the people complaining about problems with a Sony car stereo went with a cheaper (not ES designated) model. I have a pair of Sony home theater speakers I really like. I listened to quite a few, and these were the ones I liked the sound of best (within my budget, anyway).

          Their warranties are way too short, and apparently, not well honored anyway. That is a downside -- but I'd be a fool to boycott everything Sony over it. I've got my money's worth out of my PS2 so far, and had no issues. If it does break and they won't fix it free, oh well. I can deal with it. It wasn't a multi-thousand dollar purchase or anything.

      This federal law regulates warranties for the protection of consumers. The essence of this law concerning aftermarket parts is that a manufacturer may not condition a written or implied warranty on the consumers using parts or services which are identified by brand, trade, or corporate name (such as the company's makers brand) unless the parts or service are provided free of charge. The law means that the use of an aftermarket part alone is not cause for denying the warranty. However, the law's protection does not extend to aftermarket parts in situations where such parts actually caused the damage being claimed under the warranty.

If I want to watch a movie that I bought on some other format or on another hardware platform, then that is my business and allowed under fair use. It would be nice to stream the videos to any screen in the house.

    Quick summary? Sure: There are so many limitations to the "Runtime Environment" that I don't know why anyone would want to have one. Basically every hardware interface is disabled, and you're not going to get much hard disk space using that whopping 8MB memory card (so you're limited in how many external programs you can run).

    • Basically every hardware interface is disabled, and you're not going to get much hard disk space using that whopping 8MB memory card

      No, no, no. That is simply not true. As documented at this [playstation2-linux.com] playstation community web site (set up to support ps2 linux). While the complete hardware specification is indeed not made available, the device drivers (with source code) allow access to the restricted i/o devices. So you WILL have access to the hard disk, although you won't be able to make cd/dvds that you can read on the ps2.

      Also, while the i/o and sound subsystems are wrapped up in the RTE, by contrast the EE cpu, the vector units, the DMAC and the GS are not only fully open for you to play with, but their specs are provided in the proper system manuals (provided on disc) and libs tools and source code are provided to help you use them. Put another way, you have full access to the graphics and cpu side of ps2. This is great for anyone wanting to play with the ps2s awesome graphics power, and a real opportunity for anyone wanting to get into games development!

      The DMCA prohibits you from circumventing protections designed to prevent you from gaining unauthorized access to a copyrighted work, but not from circumventing protections that prevent you from making a copy of a copyrighted work. So their ability to enforce whatever restrictions they have built into the device depends upon which restrictions you're trying to get around. Of course, the question really is moot if you're only doing it for your personal use, since they'd never know about it. In effect, you can do whatever you want as long as you keep it to yourself.

    I hadn't realised until now how that was done, they must be using the same sync on green on/off functionality to restrict our playback.

    When this was first discovered at launch a lot of people (myself included) were upset about this, if you want to play games at their best AND watch dvd's you have to keep switching leads. Sony claim they HAD to limit playback in this way (cos of the marcovision thing, I think), but most standalone dvd's over here, including ones manufactured by Sony DO let you play dvd's over an RGB lead.

    Thankfully DVD Regionx [dvdregionx.com] from Datel enables dvd playback through rgb, as well as allowing discs from any region to be played.

      This isn't very believable explanation from Sony. It is true that Macrovision has not been specified for RGB, only composite and S-video, but that's because most of the consumer-level equipment can't record RGB signal. And because VHS works with composite anyway it doesn't even matter.

      Of course RGB signal is far superior to both S-video and composite, because all color components are separate, and because it is the "native" format of CRT-television, and every additional signal conversion will degrade the quality of the picture, no matter how it's done. Also, RGB doesn't have NTSC or PAL color encoding (because it's RGB, duh), so with RGB PAL-television doesn't have to support NTSC to watch imported NTSC-formatted DVDs in color and full quality (and vice versa). Actually, this might be more realistic reason for out-of-box PS2 not displaying RGB correctly with DVDs...
      • Interesting. I don't buy Sony's explaination either. Course you'll still need a 60Hz compatible TV to display an NTSC signal (even if it is an RGB one), although if your telly supports RGB it will almost certainly support 60hz. This applies to import games too, although you'd need to get round the copy protection to actually play an import ps2 game anyway.
    • According to info on the PS2/Linux forum, access to a sync on green monitor is only needed on initial bootup and installation. The video output can supposedly be reconfigured to output to a television afterwards. I don't get a sense of anything draconian from Sony or their forum reps on this (or other) issues related to the Linux kit.
    • I don't think sync-on-green is a terrible conspiricy on Sony's part .... it's very simple - the box has a TV output (not one designed for VGA monitors) - either composite/svideo or component - that means there's only 3 wires coming out of the graphics chip (usually YPrPb - but probably able to be warped into RGB by turning off the color space converter inside). There are no seperate sync signals like there are on a VGA style monitor.



      Sony are doing you a favor - they're allowing you to use RGB output on a traditional computer monitor (but it has to support sync-on-green because there's no other way to get the sync out, not enough pins on the connector).

    I can understand why people want to hack about with proprietry hardware and do cool things with them, but what exactly is Sony's point in producing a Linux distribution? From my point of view, they're doing it to keep (in all reality) the minority of box-hackers happy and maybe to prove a point that the PS/2 really is versatile (maybe a plot to scaremonger Microsoft with it's XBOX and the ability to make it do other stuff).

    So, in say 6-12 months time, you're going to have PS2's and XBOX's running Linux. Sure, they're powerful machines (the latter comes with faster bits and more I/O), but is there any serious application? The XBOX is fairly bulky, won't really be very space-saving in a rack, but sure, it's a cheap webserver.

    It just seems to me that Sony are going to a lot of effort to prove a point - what that point is i'm not quite sure.

      Sony are trying to resurrect the "bedroom games coder", and if they can get talented people to learn THEIR architecture it could well benefit them. People cutting their teeth on this system will have a much better chance of a job in the industry, which will mean more games and so more licensing money for Sony.

      What others have said, about attracting budding developers, is true, but it's not the real story.

      The console industry represents a new revenue model for the "personal computer industry" - and it may mean the demise, or at least marginalization, of the PC in the home. You see, Playstation represents 40% of Sony's entire revenues (yes, Sony as in Sony music, pictures, VCRs, telephones, PDA's, computers, etc...). That's an enormous amount of money. And they sell those consoles at a loss for quite a while, too. How, you ask? Because every time a game get's sold, they get a piece of the action. They've used their hardware platform to become an indispensable middle-man, and it's making them filthy rich.

      Microsoft, ever vigilant, realizes that a lot of their revenues come from home users, and only games really drive sales of home computers. Console game sales have been spanking PC game sales for some time - to the point where, in a few years, the PC game industry will find itself in a state of serious decline. If not for email, web browsers and word processors, not many people would buy PC's at all. And by the way, consoles, starting with the Dreamcast, are already doing email and web browsing.

      It's simple economics - console? $200-300. PC? $500 and up. And for a good PC, that can play the latest games? $1500+. I'm sure you can understand why consoles have an order of magnitude more penetration than PC's.

      Microsoft understands this, and that's why the XBox has a hard drive. The console is going to be able to surf and do email and IM and, eventually, do word-processing (USB/ethernet printers!), TiVO-like functionality, etc. etc. That's convergence, baby. And at that point it's replaced the home computer, and PC's are something you only see at the office or at a hobbyist's house. PC games will stop being ported to the console and start being ported from it, if at all (this part is well under way).

      Sony is a threat to Microsoft - Bill earnestly wants to keep owning the "home computing" market. They want all those "home consoles" to be running Windows. They want to be the middleman for every game and application sale in the home. The XBox is a multi-billion dollar loss-leader predicated on this very notion.

      Sony is a very smart company. They're savvy, they're well run. They know the score, and they have a big first-mover advantage. It's going to be a bloody fight. We know that Microsoft intends to make the XBox into a $300 home computer, based on Windows, to run "consumer applications" along with consumer games, and be waiting at the finish line when the race is over. In this round, Sony just introduced a prototype for _their_ consumer applications platform.

      It's Linux.

PC games will stop being ported to the console and start being ported from it, if at all (this part is well under way).

        As I understand it, that was their original plan, but the PC manufacuers balked. They made it clear to Microsoft that it was in it's best interest to keep to operating systems and stay away from the complete package. Perhaps eventually Microsoft will be up for a war on that front but at least as far as the XBox is concerned, they gave in.

        The result, it would seem to me, is that Microsoft will continue to encroach further into the home market but won't come out with the "total solution" unless they can guarantee it will be successful. If they were to leap too soon, they would effectively be declaring war on the whole rest of the computer and home electronics industry.

        • Oh yes, absolutely.

          They already have the hardware and software to do a "totally converged" XBox now; they held off on that because they want the XBox to win as a VG console first. If it loses, they haven't exactly broken with their retail partners - yet. But if it wins, or even comes in a healthy 2nd, then they're ready for converged XBox variants in the 2003-2004 timeframe.
      • Not again. Every few years when a new console is released someone makes exactly the same statement, I'm not saying you are wrong it might well happen this time (especially with MS involved) but its been predicted on a regular basis for almost 10 years.... The PC is dead long live the PC.

    I keep seeing people who don't understand what "sync on green" is, and this guy is one.
    <Electronics_lession>
    For *any* monitor, it is required to know when a horizontal scan line starts, when it stops, and where the top of the screen is. This information is called sync, and is seperate from the video data that paints the image.

    In a normal, modern monitor, five signal lines go to the monitor:
    1. Analog red
    2. Analog green
    3. Analog blue
    4. digital vertical sync
    5. digital horizontal sync


    Now, the hsync line is in one state while the monitor is scanning across the display, and another state during the time the electron beam is being swept back across the display (the horizontal retrace interval). The vsync line is in one state when the screen is being painted, and another when the beam is brought back to the top of the screen (the vertical retrace.)

    Now, in older monitors, to save signal lines, they used a technique call "sync on green". During the normal horizontal scan, the green line was at a voltage between 0V and 1V, with 1V being full on green, and 0V being no green. During horizontal retrace, the green line went to -0.5V to signal sync. During vertical retrace, the green line was -0.5V during the whole scan line, and went to 0V during the horizontal retrace. By suitable filtering and phase-lock techniques the actual sync signals were recovered from this. Thus, a sync on green monitor required only 3 signal lines.

    Now, if you take a normal monitor, and connect it to a sync-on-green system, the monitor's sync inputs will be undriven. A multirate monitor will simply turn off it's drive to the screen, assuming the computer is turned off.

    Sync on green has nothing to do with "synchronizing the red and blue signals with the green" - they are synchronous in time already.

    Your best bet for such things is to go to a computer graveyard, and try to find an old monitor. Many older monitors would do sync on green as well as normal discrete sync.

    What I don't understand is why everybody is getting so excited about this. Sony is locking you away from the hardware - without a massive RE effort you are not going to be able to do much with this system. For the price of the PS2 and the Linux distro and hardware you could by far more useful devices (until somebody cracks all the hardware protection). Assuming somebody does manage to get raw HW access, Sony will make that person disappear in a puff of red smoke.

    Why don't we all just ignore these people until they learn to play nice with others? Look at the Atari 2600, the Apple ][, the PC. They were successful because people could hack them. Sony and Apple learned the wrong lesson ("We must have total control! Nobody BUT US CAN MAKE MONEY OFF THIS") rather than the right lesson ("Hardware like parachute - works best when open.").

    • Unfortunately for IBM and Apple, even though the platforms were immensely successful, it wasn't them who made the real big money - it was distributed among a lot of other players. Sony cares about making money rather than standardizing an open platform.
    • SGI Monitors are Sync-on-green and there are plenty of them that have dual connectors.. both 13w3 (sgi/sun connector) and HD15 (IBM PC). HD15 is also easily convertable to DB15 available on most macs (except some new ones with HD15).

      SGI monitors can go for quite cheap, although they are very good quality. I recently purchased as refurbished (but in EXCELLENT quality) SGI monitor with dual inputs for $175.

      I'm waiting on a high-quality HD15 cable to arrive via mail to test out the dual-input stuff.. but the 13w3 connected to my SGI Octane is quite good :)

        Another guy (http://perso.libertysurf.fr/lgranjon/electronique /sgi2pc.htm [libertysurf.fr]) has documented hacks for the GDM20D10 (Sun) and GDM20D11 (SGI) to run on a PC. It's in French, but the important information is language-independent.

    • Don't forget that the PC wasn't hackable by design. IBM used off-the-shelf parts because that was the cheapest way to go. If it hadn't been for Compaq reverse-engineering the BIOS, IBM would have been happy to leave the platform closed (until somebody else came along and did it). Don't forget the IBM PS/2 either, their attempt to reinstate their control over the PC architecture.

      Hardware companies are just much more sophisticated nowadays than they were then, just like consumers. There now exist many more tools (technological, ideological, financial, legal) with which to fight their competitors/consumers and keep proprietary technologies closed. To big business, proprietary = $$$. Apple knows relatively well when and when not to apply this concept, and I hardly think they consider it "the wrong lesson" learned, since their attempt to open the Macintosh really just ended up biting them in the wallet while not really expanding the market.

      < tofuhead >

      • Bzzt. Wrong!

        The entire BIOS assembly code was printed in the manual for the IBM PC. The code was copyrighted so nobody could make a clone, but anybody could read it and use that information to program the machine.

        What Compaq did was "reverse engineer" it by having the reverse-engineers ask questions of other people who could look at the assmbly code and answer the questions. They could also test things on a PC, but they could not look at the assembly itself. This was a legal workaround of the copyright and allowed Compaq to make a clone.

  • From all appearances, they appear to be doing handstands to try and comply with the GPL, and yet still maintain control over their IP. Seems like that's okay to me - how many companies have just ignored the license completely?

      Sony are Nazis.

      Some time ago I had a Sony CRX120E CD Recorder which had problems with CD-Text. I called Sony support.

      "Yes, it's a known problem. You need a firmware upgrade."

      "Oh OK. Where can I download it?"

      "You can't download the firmware. You have to send the device to a Sony service center and they will upgrade it for you. It will cost 50 DM."

      "Lady, you can <censored> my <censored>."

      I was pissed. I frantically searched the web for the firmware. The only thing I could find was the firmware for the CRX140E on the Dell website. The CRX140E is an 8x burner while the CRX120E is a 4x burner. I thought it was highly improbable that this would work, but what did I have to lose, I had to send the burner to Sony anyway.

      I hacked the Dell flash program to work with the CRX120E and flashed the firmware. Naturally, it didn't work. The burner was dead. Wouldn't even respond to ATAPI commands. The next day, I sent it to the Sony service center.

      A week later, I get an email from the Sony service center.

      "We weren't able to flash the firmware. The burner doesn't show up on the IDE bus. We will have to replace the main board, which will cost <some ridiculous amount> DM."

      OK, so these bozos can't flash the firmware in-circuit. Great "service center".

      So I replied:

      "Alright, send it back to me, maybe you could put the firmware on a diskette and put it with the burner, so I can flash it myself, after I've built my own freakin flash programmer?"

      Response:

      "Our policy is to not give out firmware. But we can dispose of the device for free if you want that. Otherwise we would charge you a <some ridiculous amount> return fee for P&P."

      So, this was the last Sony product I've bought. Ever.

    It just doesn't make sense to me as a consumer -- if this PS2 Linux allowed you to do anything with the system, would that not drive MORE people to BUY a PS2? Oh wait, that's right -- Sony sells them at a loss, and hopes that the software makes it up.


    Oh hell, i don't know. Someone needs to hack it up so I can put a kernel on it that isn't 3 YEARS OLD.

      I'm kind of in the Happy/Sad camp myself. I was kind of excited that the PS2 had really neat hardware that I thought I'd get to play with. I guess not. I thought they would have least provided a layer in their RTE to allow us access to things like the 5.1 encoder. It'd be kind of fun to write stupid little demos and such. I don't mind so much about having to boot from the CD/DVD. I kind of expected that.

      What would have been nice (and this doesn't surprise me) is being able to mount the memory cards as is. BUT I can totally understand why they aren't allowing it. Though if someone makes a hack for that, it'd be way fun.
    • The reason that you have to boot off a CD is so that you can still play games normally.

      The boot process is very touchy and it makes sence to not disturb it, if it altered the boot processing by having the HD in there, it might cause problems for some games.

      They are not selling you a computer. They are selling you a 'limited' development kit. The whole point of this product is to get people to develop hobbist games for it (and not the XBOX). If you're not into throwing your time away making video games, then this is not for you.

      It might be interisting to see if you could use this to build your home entertainment intregration device, but why would this be any better then just a normal PC? PCs can do more and cost less! This is just another toy to play with unless you are really looking for a way to break into the console games industry, for which this could be great. Assuming that you want to spend the time to learn the tools.

      They've had this since the PS2 was invented, doesn't anyone remember the PS2 TOOL? It was a dev station that ran linux. Probably had more RAM and whatnot, but it was for debugging. I saw one at the GDC last year, they were neat but again, they are just for developing games.

      This will run web browsers like crap and generally be slow compared to a NORMAL PC, but if you actually learn how to use the CPU and do some assembly work, it might be worth it. (maybe)

    I have a japanese ps2-linux kit (although really the only thing that makes it japanese is the machine it's running on) and I am personally very glad I have it.

    1. as a developer, this gives us a cheap way to give artists/designers tools that actually show how elements will look on the TV (colors), and how PS2 specific art (graphics/sound/etc) will be rendered. it is a huge savings to be able to use TCP/IP and open-gl for these tools. it also makes working from home a bit simpler, and who can argue with that?

    2. as a programmer, I get to program two things that I enjoy (just for the hell of it) - linux and ps2 hardware - at the same time. sure, I have a few PCs here that would kick the linux kits ass easily at generic apps, esp. memory-hungry and cpu-hungry apps. but just for the fun of using linux on an embedded system, it's great.

    and for a wannabe console game programmer, shit -it's an awesome place to start. you can begin with the familiar ground (linux/open-gl/etc) and slowly move to the real hardware specific features.

    3. as for GPL vs. Sony's IP rights, I think some people around here have this impression that there is some guy at sony "headquarters" in japan making this hugely compicated agenda that is surely not in the best interest of the open software crowd. I'm pretty damn sure this isn't the case, and as a matter of fact, I think there are some people at sony who have gone pretty damn far (maybe even slightly beyond what their lawyers would consider comfortable) to show their support for the open software crowd. some people there do care, but some don't. same as everywhere. and instead of bitching about it, I'm damn happy that they've taking this starting step (opposed to how closed the PS1 was).

    there were probably a couple of people at sony who went to bat saying that they should release this linux kit because there'd be a ton of people who'd be very glad to have it. and that stance was probably pretty unpopular. so the message I want to send to those guys it "hey thanks, great job. good start!" so that maybe in the future, they'll go a little bit farther next time and have even fewer things closed.

      And the reason for this is? Personally, as a developer, I could care less if the system I'm coding on has an open or closed OS. Very few games, if any, are going to made for Linux on PS2. Those that are won't take advantage of the underlying hardware - not only because of the reasons stated in the article (that Sony's version of Linux hides some of the hardware) but also because the system wasn't built to run games in Linux. It was build, mastered, and tweaked by engineers to run in its native enviroment.

      I sometimes think arguments for "openness" are silly, particularly on devices that hardware manufacturer's created to be closed. You can argue all you want for "open standards" - it isn't going to mean jack to the millions of PS2 (and XBox, and GameCube, etc.) game players out there who don't care what OS their system is running, just if the graphics are fast and the control is solid.

    The reason PS2 Linux was made in the first place is to provide an inexpensive dev-kit for Japanese students which are looking to enter the games industry. It's not a bad idea in that regard. I'm pretty puzzled why these did this in the West though. They asked if there was much demand and naturally rather a lot of people put their hands up and expressed basic interest in the PS2 Linux. I'm not sure that there was any level of understanding (and still isn't) on why they were doing this in the first place.

    In no way was this designed to be some sort of feasible Linux system in a general sense. Sony don't particularly want you hacking about making drivers and doing weird things with their hardware. In fact they've made it pretty damn difficult to do so. And as for ideas on hacking it to gain more access... I respecfully suggest that people making these overtures don't have that much of an understanding on what the PS2 hardware is like.

    However if someone absorbs much of the included hardware manuals, gets a handle on some of the DMA issues and maybe learns a bit of vector unit assembly then they're some ways down the road in becoming a useful PS2 commercial developer. Is that anyone here? I doubt it.

    I'm sure the debate will continue and some hard-core Linux evangelists will crow about license issues and that there ought to be unfettered access to the hardware. That's not Sony's agenda and, to be honest, why is this much of a desirable thing anyway. Quite clearly Linux on a PC is more useful in any event.

    I'd really like to know if this will sell anything in the West at all. The demand for games developers is such that you can get an entry level job straight out of university anyway. If you're going to work on PS2 dev, they'll factor in that training on the 'real steel' dev-kits anyhow.

    If you wanted to do home-brew game development for console-like applications, the Gameboy Advance is an infinitely more feasible platform from a technical point of view. Coupled with the fact you could give a copy of your work to someone else or demonstrate it on a stock GBA, it's got to be a more attractive platform for this sort of thing.

    is broken somehow, I still doubt it will be much
    more than above.


    I'll probably be ordering one of these things.
    It seems like it will be a pretty cool/fun thing
    to have for my PS2. Probably more fun playing
    with it than some games.

    When I lived in Japan from 1992-1996, I saw the state of intellectual property there first hand. For example, normal broadcast radio does not play top 40 hits. Actually any transmission of copyrighted songs over the air, even a sample, must have a royalty paid to the publisher. If you want to listen to music on the radio, you find an American military station broadcasting on base. Japanese singers also do not commonly own the copyright to their own songs, they couldn't give them away even if the wanted to. Concert recordings are also illegal. There is also royalties you have to pay for the subtle music played in department stores, doctor's offices, and on the phone when you are on hold.

    And, except for not playing Top 40 on the radio, how is this different from the Good ol' USA? Ever heard of ASCAP, buddy? Here in the US, radio stations sure as heck pay royalties for the songs they play. Muzak is a pay service, and they've got to pay their composers. If you play CD's or commercial radio as background music in a store, without paying royalties, you are violating US law! And, how much of their own stuff do you think Garth Brooks and Mariah Carey write?

    • A number of years, in Canada, one label (Polygram, I think) tried to charge radio stations for the 'priveledge' of playing their songs on the radio. Campus radio stations rebelled and simply refused to play anything from polygram.

      Polygram first offered to let them play 'alternative music' only without any royalties. The radio stations refused. Polygram finally relented and allowed free play for all of their music. I don't know if this has changed, but it clearly shows that music companies get more than their share of value by letting radio stations play their music.

      As far as I know (in canada, at least), it is legal to play radio in a public place without paying royalties. The broadcast on radio is considered the public performance and the use of the broadcast is considered 'fair use' -- but if you pop in a CD, it's considered a new public performance -- which requires a royalty payment.

      (this information garnered from a TV news story about someone being sued for allegedly playing CDs in his restaurant).

    The more information comes out about PS2 Linux, the worse it looks. Why buy $300 worth of crap to make Linux run on an uber-proprietary system when you can buy a Dreamcast for $50 (if you can find one still) and have a platform that will boot Linux out of the box? You might have to avoid machines built after October 2000, (although there apparently is a further hack out to create a bootable disk for those machines) but I have one from 9/2000 and it booted the DC Linux disk right out of the box.

    The exciting things will happen when someone builds a lightweight Linux booter that will address everything on the DC and allow you to run games designed for Linux. There is still some work to be done to make all the hardware work, but there are a lot of hands on this project so I suspect that it won't be long before the Yamaha audio, the Conexant controllerless modem and full video access (rather than framebuffer) are fully working under Linux.

    SEGA is to be commended for releasing as much information as they have on the DC. Their attitude is also commendable: "we stopped making the machine in 2001, have your way with it." Nintendo, Sony and Microsoft have all demonstrated their lack of willingness to play ball with amateur developers. DC is the only game console which is actually FRIENDLY to amateur development.

    One last thing...look at my .SIG. Sony is the only company I can think of that is a signatory to both the RIAA and MPAA. That's reason enough to stay away from Sony products.
  • As far as I can see, the Sony release of Linus is in violaiton of the GPL.

    From the article:

    This is how the Runtime Environment (RTE) works. In order to get Linux running on your PS2, you must boot the system using the PS2 Linux DVD. During boot, after all the copy-protection stuff is taken care of, the system lays down the Runtime Environment. This is basically a layer that hides access to the SPU2 (Sound Processing Unit), the input/output processor, the hard drive, the CD/DVD-ROM system, the controllers, memory cards, USB, i.Link and other peripherals. The RTE does supply hardware looking hooks, an educated guess being faux-memory address and registers. Then the Linux kernel is loaded onto of this. There are Linux device drivers that accesses the Runtime Environment that are open source, but it's just a device driver calling in all actuality, another device driver that's closed.
    From the GPL:
    These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But
    when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.
    Given that their runtime environment is an integral part of the PS/2 Linux distribution, refusal to release the source code to the RTE would be a violation of the GPL -- and thus a copyright violation.

    Any lawyers out there willing to support/fight my conclusion??

    My guess is that taking on Sony on this issue -- besides having the prospect of being rather expensive if it actually went to court -- would probably have some interesting side effects -- both legal and media-wise.
