PSPYAPE is a port of Yape, an emulator of Commodore microcomputer family running on Windows and Unix.

The emulator imitates the C-264 (know also as Commodore Plus/4) model. Originally written by Attila Grósz and this is a port on PSP based upon the version v0.32.4 of Yape SDL.


Unzip the ZIP file, and copy the folder pspyape to ms0:/PSP/GAME/.

Put your program files on the prg sub-directory.

User guide

In the YAPE emulator window, there are three different mapping (Standard, L-Trigger and R-Trigger). You can toggle between in game using the two PSP trigger keys.

Load Program files (PRG)

Put your program file (with .zip or .prg file extension) on your PSP Memory Stick in the prg directory. Choose Load PRG inside YAPE emulator and select the program you would like to run.

Load Key Mapping files (KBD)

The default keyboard mapping between PSP Keys and C-264 keys, is not suitable for some games, and you can write your own mapping file to overcome the issue.

Using notepad for example you can edit a file with the .kbd extension and put it in the kbd directory. Please see default.kbd for the exact syntax of mapping files.

After writting your own keyboard mapping file, you can load them using the main menu inside the emulator.

If the keyboard filename is the same as the program file (.prg) then when you load this program file, the corresponding keyboard file is automatically loaded.

Furthermore you can use the Keyboard menu and edit, load and save your keyboard mapping files inside the emulator.

In that case the KBD file will be saved using the Game Name as filename. The game name is displayed on the right corner in the emulator menu.
