PS1P-Alpha 1: PSOne emulator for the PSP

Presumably the one big disappointment with Sony's FW 3.0 PSOne emulator is that you need a PS3 to download the game files to begin with, and those aren't exactly a dime a dozen. So, that leaves the stand-alone homebrew PSOne emulators from the scene. Anonymous Coder has just released his PS1P-Alpha 1 PSOne emulator for the PSP. Not to be confused with the almost similarly-named PSX-P (PS1) emulator by Yoshihiro (now v2), but looking forwards to the same functionality. There were rumors that this emulator was to be made to support only a single game. That concept was discarded as the author decided to write a single emulator to support multiple games. You can read a few words from the Anonymous Coder below.
  • The wait is worth it. I'm releasing a version that will run anything. ISO, BIN, Z and ZNX. The rest you know. scph1001.bin and images in the __SCE__ps1p directory.
  • This version has some compatibility problems which I plan to fix soon, for example the FF7 intro movie doesn't run. You can play the game though, just get past the intro using a standard PC emulator (PCSX, ePSXe, ...) and copy over the memory card file ( mcd001.mcr or mcd002.mcr).
  • Use L+R+ up/down to tweak the CPU timing. I think L2 and R2 aren't working at the moment too. --A.C.
  • P.S.: to make things clear. This emulator has nothing to do with PCSX, psx4all or any other emulator already released. The only thing I did was use for the game selection screen, the same font code that psx4all uses--it's from some GP2X demo/app.
  • The CPU thing is adjusting the counters relative speed. Note it has a % at the side. It's like making the PS1 CPU run faster or slower. The right value is at 100% (obviously) but the default is 700% (good for FF7 :P). Lots of games runn better at something lower than 700. It does nothing to the PSP CPU so you can set it as high as you want. But after some point it actually starts to be slower.
  • There's save state, L+R+left to save, L+R+right to load (or the opposite).
  • Analog can be used for controlling (as if it was the d-pad).
  • The BIOS must be called scph1001.bin and be placed in the __SCE__ps1p directory along with the BIN, ISO, IMG, Z or ZNX images. Other BIOSes should work too but rename them to scph1001.bin because the emulator looks for this file specifically.
  • People can use PocketISO (google for it or the FPSEce page) to compress images to Z and ZNX.
  • The ePSXe memory cards must be renamed to mcd001.mcr and mcd002.mcr and placed in the __SCE__ps1p directory.
The app isn't perfect yet, but they're getting there. Something else to add to the list of homebrew PSOne emulators floating around teh interwebs.
