Cyraan writes "PSP owners rejoice! Hot on the heels of the recent exploit discovery & bricking that resulted from early test versions comes a confirmed working downgrader. The method uses a GTA eLoader that will turn any version 2.50/2.60 PSP, with the exception of those with a TA-082 motherboard (how to check without opening/voiding warranty), into a version 1.50 capable of playing all forms of homebrew. One thing that may not be mentioned specifically in the article: it is recommended you NOT use the 32mb Memory Stick that came with the PSP, as the process creates alot of log files that can fill it up, possibly causing a brick."

[+] Homebrew Community Blends Gamers and Hackers 87 comments
MSNBC is running an article on the gaming homebrew community. They examine the 'do it yourself' attitude of the folks that make mods, knockoffs, and emulations possible. From the article: "So lively is the homebrew scene that some PSP fans -- it's impossible to say how many -- say they don't buy or play new games because they don't want to upgrade their gadgets and lose their homebrew software. There's even a circulating joke slogan: 'Friends don't let friends upgrade their PSPs.' Unable to break through recent versions of the Sony software, PSP homebrewers have moved on to another trick: downgrading their PSPs to earlier versions."

      What do you mean 'not exactly DRM'? What you have is a machine that is allegely yours but won't run binaries that you wish to run, merely those that someone else wishes you to run.

      That IS exactly DRM.

      Otherwise, yes.
      • No, that is not DRM. DRM is short for "Digital Rights Management", the "rights" mentioned is "copy right". The point of DRM is to ensure that you can't use material you have bought in ways the copy right owner doesn't want you to.

        Now you could extend DRM to mean "run unauthorized programs" but that's not really the norm. That's what "trusted computing" and all that crap is about.
        • "...in ways the copy right owner doesn't want you to."

          The right that you're talking about doesn't exist. The copyright (one word) holder has control over publishing copies and public performance, and that's it. Any owner of a legal copy may USE his copy in any other way, with those two exceptions.

          DRM is often attached to material which is also copyrighted, but the 'rights' being managed are rights that don't exist in copyright law.
          • If the "rights" claimed by DRM is correct or not is besides the point. The point of DRM is to give the copyright owner more control than they usually have.
          • No [wikipedia.org].

            Some (Stallman) call it "Restriction Management" but those people are the minority.
            • The difference is that if you own the Linux box, you can do anything. User accounts are something you use to limit the ability of others to hose your computer.

              Sony's DRM limits the ability for you to use your own property. (Unless you're just renting the PSP, in which case Sony can do whatever they want. Of course, you could sue them for breach of contract if they said you could do something that you can't. If you don't like the PSP's DRM, though, why not just not buy one!? Let Sony go out of business.)
    • What most people want to do with the system is to make it run illegally downloaded games, most of them meant for other systems and many still being made and sold by their rightsholders. This hacking is also contraproductive since it makes sure there is no real market for a handheld without these restrictions since people just buy a PSP and crack it.
      • I wouldn't qualify that with "most". MOST of us(ok, I'm not one, I refuse to buy anything by Sony at this stage of the game) actually like playing with hardware and making it do things it wasn't originally designed to do. MAKE magazine is a shining example of this attitude.

        Kind of like emulators for PCs. So should Windows try and keep me from running Snes9x?
          • Selling at a loss is Sony's fault. People want to do home brew stuff. They should be able to do home brew stuff -- they bought the hardware.

            Now that it's been made clear Sony is going to make it a bastard to have homebrew games/etc, I imagine people who want to do said thing won't buy a PSP. They'll buy a GP2X (or whatever it's called).

            Just because you run NES games on your PSP doesn't mean you're not buying PSP games. Watch Sony make it so that new games won't run on 1.5 anymore, if they haven't already. T
              • I'm not saying Sony's never made a profit, never meant to imply that, I just meant over the last two or so years; I get that some of that is the PS3 R&D (and soon, I imagine, hype and ad campaigns).

                I think the main reason homebrewers are buying the PSP is because of the popularity; I hadn't even heard about the GP2X outside of a mention in Wired until recently, and then only on Slashdot or from the guy I know who bought a PSP primarily to run old system emulators on.

                You're looking in the GP32 (the previous model) section. The GP2X has superior (and built-in) mp3 and video support, is much faster - it has two processors, each of which is twice as fast as the old model's CPU. My GP32 can play Phantasy Star 4 (Sega Genesis) and a bunch of Turbographix games flawlessly, among other things. Apparently the GP2X has excellent emulators for Genesis/TG16/SNES, though can't say for sure since I haven't received my GP2X yet. :) But since it has considerably better hardware, it seems reasonable. The only emulation that is supposed to be buggy and slow on the GP2X seems to be PSX (because of the 3D) and DOS emulation.
                • SquidgeSNES doesn't quite hit fullspeed yet, but it's close enough that many games are playable. I've clocked 20+ hours in Dragon Quest V alone on it, and Actraiser plays nicely as well.

                  Depending on the game, YMMV. Don't miss gpfce (NES emu) either.

    Backdater. Downgrade seems like you're making something worse which is actually the case with some "updates" that are provided by some makers. Examples of this includes TiVo updates that remove features like commercial skipping. It would most certainly not be an upgrade. And to go back to something with better features once removed or modified would not be a downgrade. But to go back to a previous version that is more useful in some way, I would call "backdating." (please, no gay jokes)
    • The PSP OS is undergoing a transformation to a previous version, even if it wasn't originally installed, the PSP community should stick with established computing jargon. The PSP has a motherboard, video display, cpu, input devices, memory for temporary and long-term storage and an OS that is updated periodically. Smells like a computer to me.

    • 1.5 Didn't have the web browser that the later versions have. There are some other things too, like I think Sony added an RSS readers.

      In this case, it is a downgrade.

      • Not really. DEVHOOK makes it almost trivial to use the 2.0/2.5 firmware features from 1.5, and only adds maybe 10 seconds to the time it takes to get things up and going.

        Going back to 1.5 doesn't mean you lose all those features anymore.
        • Will DEVHOOK let you play games you purchased without upgrading your firmware, or is there any program that will? I'm at 1.5 still and would rather not upgrade to play the last game I purchased.
    • That'd be true if 1.5 had more features than later versions. It doesn't. The only 'feature' is has over the others is the glitch/bug/exploit that allows unsigned code to be easily executed. It has no browser, to streaming video, etc etc. This is a downgrader in every sense of the word.

      Note that the program was on beta 5-- the previous four test versions bricked PSPs, period. They were outputting a whole lot of debug data about each stage of the flash, it seems, since there are some complex steps to get things to the right point. It's not just writing bytes-- this downgrader apparently actually borrows chunks from the official PSP updater and does some interesting tricks to bypass various protection mechanisms.

      The logs were there purely to figure out where things went wrong; nobody expected this version to work.

    I went out and bought specificially a 1.5 to enjoy the homebrew. I ended up playing the homebrew stuff more than the pricey games.

    But looking at the downgrader instructions and such, AND knowing the risks of "bricking" your $250 game system, I'm glad I traded it in for a DS.

    While the PSP may have a bunch of fun features, getting to the homebrew stuff with Sony's anti-blessing is just a hassle. A lot of the homebrew stuff is about as fun as recompiling a linux kernel..on a video game system. I won't try to make any Linux technobabble / PSP technobabble comparisons since I've heard nothing but good things about the GamePark.

    So if you like fighting against Sony, the complications of Linux(upgrading/downgrading/copying files), the risk of malware(bricking your PSP, ie worse than any Windows malware), pricey games, and a failing media format(UMD), the PSP is for you!
