    psp NJ`s New CPS1 Emulator WIP News

    NJ has posted some excellent WIP news over at his site of his latest project for the PSP, A CPS1 Emulator, CPS stands for Capcom Play System which supports some of the best Arcade games ever.



    Our excellent translator b8a has posted what NJ posted on his site:

    Sound emulation: 10%
    Input emulation: 80%
    CPU emulation: 80%

    As I've achieved my initial goal, I decided to go ahead and post the news.
    Everything other than scroll 2's row scroll, screen flip, and rotation (which probably won't be implemented), the video emulation is complete, and everything else is far from ready. SFZ CPS Changer version is also currently working.
    It feels like Final Fight and Street Fighter 2 are a little on the slow side.
    This is just at the stage where I've just got it working and I haven't made any optimizations yet, but it's guaranteed to get even slower when Row Scroll is implemented.
    As for CPS2, the M68000 memory access causes a drastic drop, so I think it'd be pretty challenging to accomplish.
    Not to mention that there's not enough memory for most of the games.

    Excellent news for the PSP Scene.

    Its only a WIP but sound good.

    google translation:

    Development circumstance
     Video emulation: 50% - row scroll not impremented.
     Sound emulation: 10%
     Input emulation: 80%
     CPU emulation: 80%

    Once because aim was attached, information is increased.
    As for video emulation whether row scroll of scroll 2 and the picture flip and revolution (it does not mount,)
    Other than generally as for end and other things when still you said. Also SFZ CPS Changer edition once correspondence.
    Final Fight and Street Fighter 2 are the feeling whose operation is a little slow.
    Temporarily, still optimization has not gone at the stage that, it is moved, when, but it mounts Row Scroll
    Furthermore it is secure to become heavy.
    Because as for CPS2, the memory access of M68000 decreases substantially, it is rather harsh, is.
    Most games are not enough memory, is, die.

    Thats fookin amazing news though if NJ is working on CPS1 emulation!!!!!

    Mame4all is cool but there hasnt been any updates for quite a while and theres quite a few games that dont work properly... but if NJ is on the case for cps1 emulation then hopefuly there will be regular updates. If his neo geo emulators are anything to go by (hes possibly the hardest working coder around) then he'll soon sort it out for the PSP.

    This is great news!

    I've updated the sound so that it plays YM2151. When not at 11025Hz, it's too slow to be playable.
    OKI6295 is nothing but noise and isn't playing back well. Hmm...

    He’ll soon sort CPS1 out!

    ...and i wouldn’t put it past him to get some stuff running on CPS2 in the not to distant future. He said “As for CPS2, the M68000 memory access causes a drastic drop, so I think it’d be pretty challenging to accomplish”, but that hasn’t stopped him performing miracles already on PSP!

    I'd love to see Dungeons & Dragons tower of doom, Pocket fighter, AVP etc working on PSP (maybe im dreaming a bit now).

    IDEAL!!!!!

    Maybe some of his optimisations could be used to help MAME along?? This sounds like a great project though!
