Controversial developer, Yoshihiro, has released PSX-P Alpha 2, the Sony Playstation (PS1) emulator. It remains unplayable; yet some tremendous progress has been made with advancements to graphic rendering. The downfall — it’s still very slow and lacks sound. Nevertheless, a great improvement thus far.

If you’re really looking forward to PS1 emulation on the PSP, and you’re not too concerned about homebrew, I suggest waiting to see what Sony has in store for us come the release of FW 3.0.

In the meantime…

Update: Maybe not so remarkable afterall… I’ve received numerous emails indicating Yoshihiro has actually ripped most, if not the majority, of code and released it as his own. In actual fact this is PacManFan’s PSPSone emulator released a few months ago. We’ll continue to keep it hosted for now; nice work PacManFan. ;)

Wow… Another remarkable accomplishment today… Yoshihiro has released the first beta of PSX-P.

PSX-P emulates the Sony Playstation (PSOne) which marked its spot on the scene back in 1994-95.

PSX-P has been confirmed to work on firmware 1.0 – 1.50, and 2.00 – 2.60 via eLoader. Of course this remains in the early stages of development so you shouldn’t expect complete stability just yet. In fact it’s mentioned that execution is slow due to lack of an optimized dynarec (dynamic compiler). Nevertheless — give it a try and provide your feedback below!

ROMs are distributed in ISO or BIN format — we will not provide links to these; however, we will gladly provide you with the URL to the required SCPH1001.BIN file, the PS1 BIOS.

Place the BIOS file in: ms0:/PSP/GAME/__SCE__psxp/bios
Place the ROMs in: ms0:/PSP/GAME/__SCE__psxp/rom

Enjoy!
