About Save Files

In game SRAM save data (*.srm) is saved when you return to the PSP menu via the home key, select a different rom, and put the PSP into sleep mode.

So if a game hangs before you have a chance to do this the in game SRAM save data will not be saved. You can manually save SRAM save data by selecting SRAM SAVE from the menu screen.

  • State save data (*.00?) includes content of SRAM. Compatible with the original Snes9x.
  • Menu settings will be saved everytime a game is played (*_psp.cfg).
  • The default settings is stored in the same folder as EBOOT.PBP (uo_Snes9x.cfg).
  • All save files, cheats data (*.cht) will be automatically stored in the SAVE folder. Compatible with Snes9x.
  • Turning on the thumbnail save option will result in a compressed version of the screen being saved (*.tn?).
