Troubleshooting
Game not showing up?
PSP games should be in the ISO folder or subfolders (01PSP 1-25, etc.). PS1 games go in /PSP/GAME/ subfolders. Emulator ROMs go in their respective /PSP/GAME/07Emulators/ folders.
Game won't start?
Try copying the game again. The file may have been damaged during transfer.
Out of space?
Delete games you do not play anymore to free up space on your memory card.
Emulator not finding ROMs?
Make sure ROMs are in the correct emulator folder inside /PSP/GAME/07Emulators/. Use the emulator's file browser to navigate to the ROMs folder.
PS1 game not working?
PS1 games must be converted to EBOOT format to work on PSP. Make sure the game files are in the correct folder structure (05PS1 or 06PS1 folders).
