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 Key Mapping files (KBD)

For given games, the default keyboard mapping between PSP Keys and TI99 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 in the main menu. If the keyboard filename is the same as the CTG cartridge file, the corresponding keyboard file is automatically loaded (when you load the cartridge file).

Use the Keyboard menu to configurate, 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.
