Playstation Emulator for PSP Released

Posted by ryuzaki0 on from the because-the-games-editor-misses-the-dreamcast dept.

Joan Cross writes "Today sees the release of the first Playstation Emulator for the PSP to play commercial games; the emulator plays games such as Ridge Racer at up to 10fps, and once dynarec is added full speed is easily in grasp. The emulator works on all PSPs except those with firmware 2.80 and higher." Update: 09/26 12:19 GMT by Z :Fixed dept.

    once dynarec is added full speed is easily in grasp.

    Yeah right. The authors of the PSP SNES emulator basically stated that even with dynamic recompilation and a full rewrite, they could see no more than a 10% speed increase over what they already have, which is playable, but not full-speed.

    Somehow I highly doubt that the PSX emulator (at least the homebrew one) will accomplish that feat.

      Running MIPS code at full speed on a MIPS CPU is clearly impossible, even with a 4-5x clockspeed increase.

      Running MIPS instructions on a faster MIPS core isn't the problem. It's emulating the support hardware of the Playstation -- the sound hardware, the Geometry Transformation Engine, the Data Decompression Engine et al -- that requires a lot of overhead, and has to be done mostly in software. Even where the PSP hardware offers a close analogue, you'll need at least twice the power of the original Playstation, to translate the opcode and then execute it.

  2. License Violations ahoy! by TheBlueCrab · · Score: 5, Informative

    This emulator is a deriative work of PCSX (see the linked forum post), as well as the P.E.Op.S Soft SDL driver, and SDL itself. It violates the license of all three of those by not releasing source or an offer to get the source. (Heck, it doesn't even acknowledge that its a deriative work of any of them.)
