PSP Firmware Downgrader Released

roka writes "SonyxTeam has just released a downgrader for the PSP using the toc2rta 2.0 overflow in libtiff. This has been tested and found working by PSP news sites. This is basically opening all sold models of the PSP to homebrew applications and will boost homebrew software development for Sony's handheld."

    Admit it.

    Now we're all just waiting for Sony to thow it's Intellectual Property Toys out of the pram and let the attack dogs (lawyers) loose.

    A sorry state of affairs.

      Need to correct you on something:

        The PSP games will never update the firmware automatically or their warranty offices will get a shitload of bricked units. Firmwares require AC power to be connected for a reason, you don't want your battery going out during flashing.

      However, many newer games require a certain version of firmware to run. Currently, you can trick these by using software that modifies the flash to show a different version number. However, eventually, games will start looking for unique encrypted firmware features. There are teams already working on making newer firmwares run over the current ones to allow access to features not available on your flash. There is already a firmware emulator that allows someone to load up 1.0, 1.51 or 1.52 firmwares on a 1.5 PSP

      However, I'm optimistic that an exploit will eventually be found that will use something the PSP requires to keep older games functional.

      Never piss off the hackers, they always win:)

    How many people are really using this stuff, vs. the total user base?

    The mainstream market isn't even aware hacks like this exist (much less where to find or how to use them), for the most part.

  3. How long till they patch by Brianech · · Score: 5, Insightful

    It didn't take long until they patched 1.50. This has been an ongoing process. They will patch the overflow, make the next gen of game require the patched update (Although there is a loader that fakes the psp's firmware). All this means is that everyone who buys a PSP up until the next firmware starts hitting the market will be able to run homebrew, and we will hear whining from all the 2.X people about being locked out of the homebrew scene. But its good news for a little while!

  4. Long awaited by Sv-Manowar · · Score: 5, Insightful

    At last, a second chance for those who upgraded their original 1.0 firmware and instantly regretted doing it once the homebrew hacks were discovered. This hack comes at a much better time for enthusiasts to benefit and make use of the hack, if they desire, before Sony patch the hole (not to mention leaving a large number of PSP's out there on the available market running a hackable firmware..). Of course all this would be moot if Sony would just embrace the developer community surrounding the PSP and support it appropriately, instead of them having to go to these lengths.

    Well, if by non-evil purposes you mean "Allow people to play bootleg ROMs of games they downloaded off the internet on their PSP."

    I don't think people are excited over the ability to play various asteroids clones on their PSP. Oh, maybe they're holding out for that killer homebrew Blackjack game, or they're really hoping they can downgrade their version to play Pong with their $250 device.

    No, I think pretty much everyone just wants to run emulators of NES, SNES, and Genesis games for free.

  6. Re:"homebrew software development " ? by Dachannien · · Score: 5, Insightful

    Is "homebrew software development" the new euphemism for "piracy"? You know, how 99.99% of everyone who got mod chips for their ps2 and xbox was just so they could "run linux" ?

    "Homebrew software development" is about making legal use of the technology we pay for. Piracy is just along for the ride.

    It's sort of like how you can kill someone with a hammer. Murder-by-hammer is already illegal, but that doesn't mean that hammers should be encumbered by use management technology that both prevents homicides and blocks you from using nails made by someone other than the hammer manufacturer.

    Not true. I've had a Dreamcast since it launched, I've been downloading and burning homebrews for it since I've discovered them, yet I still loved and played the "real" games (when they were making them). The homebrews just gave more funciton to my Dreamcast, but it didn't replace the games.

    Woah, that's not an accurate analogy. Because hammers are generally used for the purposes of construction rather than for illegal purposes. And that's an important point, at least practically speaking, and as the laws appear to often be applied. The right analogy would be about bongs/water pipes. Many states outlaw them outright because they are considered drug paraphernalia, because while they "can" be used for smoking tobacco, they rarely are. Other states allow their sale and the stores which sell them claim they are intended for tobacco use only, but of course, they know they will not be used that way. Anyway... not saying which is right. Just saying that is at least the right analogy, IMHO.

  9. Different market, different situration by MMaestro · · Score: 3, Insightful
    Texas Instruments sells their TI- calculators at a profit with little intention of making a profit on the accessories (the only thing you ever need to buy in its lifetime are batteries).

    Sony sells the PSP at a huge loss (the fancy screen and marketing blitz couldn't have been cheap) and is designed to make up losses with PSP movie sales and PSP game sales. Neither of which have amounted to anything (yet).

    Unless Texas Instruments launches their own 'Virtual Boy', they're pretty much the Nintendo of professional, high quality calculators. Don't expect double digit percentage growth, but constant and consistant growth. Sony on the other hand is already in the ditch. Yes they've made some headway into the market, but so did the Game Gear (arguably the Gameboy's strongest competitor) as did the Neo Geo Pocket/Color and they both lost, horribly for the latter.

    The PSP isn't going to go anywhere if it just pushes itself with homebrewed software. It needs games. Badly. Movies are nice, but the DVD versions blow PSP versions out of the water. Sony needs to stop bashing Nintendo and give Sony fanboys something substancial to bash Nintendo.
