User guide

Key mappings

You can switch between different mappings in the emulator window (Standard, L-Trigger and R-Trigger):

• Standard mapping.
• Danzeff On-Screen Keyboard (by Danzel and Jeff Chen). ​
• Customizable IR Keyboard (from the file pspirkeyb.ini).

Load ZX81 Program files (P, 81)

Put your file (with .p or .81 file extension) on your PSP Memory Stick in the prg directory. Use the file selector in the emulator main menu to choose one program file to load in your emulator.

Load Key Mapping files (KBD)

For given games, the default keyboard mapping between PSP Keys and ZX81 keys, is not suitable, you can write your own mapping file to overcome the issue.

Edit a file with the .kbd extension and put it in the kbd directory. Sample and syntax can be found in the file default.kbd. Keyboard mapping file can be loaded them using the main menu inside the emulator. If the keyboard filename is the same as the program filename, the corresponding keyboard file is automatically loaded (when you run the program).

Use the Keyboard menu to configure, load and save your keyboard mapping files inside the emulator. The Save option save the KBD file in the kbd directory using the Game Name as filename. The game name is displayed on the right corner in the emulator menu.
