    psp NullDC PSP News Update and Clarification - Dreamcast Emulator for PSP

    drk||Raziel has posted some info on his blog regarding the Dreamcast Emulator for the PSP:

    nullDC/psp will only be for psp lite. The old(’fat’) psp just doesnt have the ram space needed, nothing i can do about that.

    The current speeds are very low, but that is expected. There is no dynarec, no optimisation, not even a single mips assembly line on the current source. Most of the current code (everything, apart from 3d rendering) is based on the pc version of nullDC, and most of this code will be replaced. So yeah, IT WILL TAKE QUITE SOME TIME BEFORE THE PROJECT IS ANYTHING NEAR USEABLE.

    The current speed (as stated by the on screen couters) is around 10%. THIS IS WRONG, IT IS ACTUALY LOWER. The interpreter runs underclocked (to make the speed bearable). This also happens on the pc build of nullDC when using interpreter (for the same reasons). The rps field (renders per second) is accurate.

    After the code is cleaned up/rewriten there are plans to port to pandora ( www.openpandora.org, realy cool stuff ) and possibly other consoles (wii seems like a nice target, ps3 if theres a way to get 3D access). ALL THIS MAY(OR MAY NOT) COME AFTER THE CODE IS REWRITEN, SO DONT ASK ABOUT IT NOW(you’l just waste your time, realy). The code will be open sourced as soon as it gets stable.

    While i think it is possible to get fullspeed on psp it is quite likely that i will be proven wrong. I CAN NOT MAKE ANY PROMISSES ABOUT THE SPEED, I ONLY PROMISE I WILL TRY TO GET IT FAST.

    If you somehow think this project is wasted time, then dont waste any more commenting/thinking about it. My time is .. mine, i can do whatever i want with it. Seriusly, if you want to say something bad just save your time, it wont realy change anything .

    There, i hope this clears up some things. If for some reason you’re still confused read over the bold parts, that will help

    Lets hope and pray that NUllDC can be ported at a playable speed, i do have faith that the coder will do his very best, exciting news for PSP owners.

    It depends really. They both have parts where they win, but emulating dc on psp would need a LOT of work. Still, it's running and I have faith in drk||raziel.

    And JKKDARK, you have a PSP?
