    I guess i'll test this but to be honest the only PSP game I really want on my phone is P3P.

    Tried it and it was very disappointing as I can't play my favourite game :cry:

    Try decrypting it. c;
    Compatibility list is short but there's only room for improvement!

    It involves running the decryptor homebrew on the ISO in a PSP (since the PSP has the decryption keys).

    you just extract the eboot.bin from the iso using UMDgen.
    run prxdecrypter on the psp, with that extracted eboot.bin in "enc" folder (make it in the root of the memory stick), now its decrypted.
    take the newly decrypted eboot.bin and put it back into the iso using UMDgen.

    however even after doing this i still get that error. hmm...

    Thanks I found it after a quick google search and its pretty simple to use surprisingly.

    Same I still get the error. I guess this emulator only works with 2 games but its unfortunate that those 2 games are utter crap.

    The site says that they have tried other games, but soon get "out of memory" errors and the like. It's going to be a while until P3P is working. :P

    I'd be interested to see how this runs on the Xperia Play. If it ran well there it could become pretty cool once it works a bit better.

    On the topic of encrypted games: The PSP's Kirk engine handles decrypting games, and it has yet to be fully reverse engineered. This means there can't be true emulation of the Kirk engine. Currently I believe there are 11 commands of the Kirk engine that have been reverse engineered. I'm not sure exactly how many commands there are, but there are more than that. I don't even know if those 11 have been done fully. Therefore, it's not possible to decrypt PSP games other than on a PSP (where with homebrew execution you can feed whatever you like into Kirk and it'll return the decrypted version).

    If Kirk were to be fully reverse engineered, games could be decrypted without a PSP and that sort of functionality could be implemented in an emulator such as this, making any ISO work (in theory), provided the game is compatible.

    On the fly decryption... But once the eboot is decrypted and inserted into the ISO, there's no need for actual PSP hardware for that reason (native decryption), yes?

    too bad the xperia play turned out to be crap, would've been perfect for this.

    And this thing runs on Android? Impressive. It'd lag like shit on my Android device.

    Correct. It's the decryption that requires the (Kirk) hardware, the rest can be emulated.
    You may be surprised. I haven't got an ISO to run yet, but I was able to run the demo cube ELF thing from the PPSSPP site on my rather low end device (600Mhz processor) quite smoothly. I'm sure performance will be much worse with an ISO, but I was shocked that the demo thing ran as well as it did. Bear in mind the PSP was a 333MHz device, and many games only had access to 222MHz of that. I know having a proper OS (i.e. Android) running takes up resources, but still, results seem surprisingly good on relatively old hardware such as shown in the video in the first post (I think that's a Nexus S, which is a reasonably old phone now).

    Anyone got a commercial ISO to run yet? I've been trying but I don't want to waste my time if it's not going to work...(I haven't gotten round to decrypting the EBOOT yet).

    Wow amazing. Super excited as I have a top spec phone. :) Don't expect anything good quality though.

    DS emulation isn't at perfection hmm

    Well, I have 3 PSP games already (MH, P3P, Cave Story) and I'll test them, although I'm guessing they won't work. Also, I read the FAQ and it says there is a possibility of this emulator being ported to other consoles.

    http://www.ppsspp.org/development.html#tasks (Scroll all the way down)

    The Wii, Blackberries, and the original Xbox are included. Wow, that's amazing.

    Tried quite a few and they don't work. I guess its a bit to early to be doing this, hopefully progress and be made with this emulator soon.

    From their compatibility page:

    Android Device Compatibility

    PPSSPP should work on all modern Android devices. It's been confirmed to run on the following:
    • Nexus One (the slow GPU will probably be a problem later)
    • Nexus S
    • Nexus 7
    • Galaxy Nexus
    • Galaxy S2
    • Galaxy S3
    • Xperia Play
    • Asus Transformer
    • Ainol Novo7 Advanced II
    ...of course, being compatible won't mean it'll be playable in the long run, but it's certainly something to keep an eye on. :)
