There is no need to manually import a new one. So, first, there is actually a 'keycodes' file provided with the RetroPie release of BasilikII. Would you share with me a better solution?

Keycodefile /home/pi/RetroPie/roms/macintosh/keycodes And I should mention my keyboard works perfectly with the expected layout under other RetroPie emulated systems (Amstrad CPC, C64, Amiga.)Д¬opy the file keycodes from the BasiliskII installation on my Mac to the /home/pi/RetroPie/roms/macintosh RetroPie directory and changed the config file /opt/retropie/configs/macintosh/basiliskii.cfg with these lines: keycodes true On other platforms (I use BasiliskII on my real Mac, too), you only have to use a file, named 'keycodes' to get the layout of the host machine under the emulated environment. This behavior is supposed to be normal with BasiliskII. And, if I turn the keyboard into a British/American layout under System 7.6.1, it becomes AZERTY (the French layout.) but, still, the numbers and other symbols are wrong. Worse, my keyboard is configured as French in Retropie and configured as French under the emulated Mac System 7.6.1, but its layout appears as a QWERTY one when I type under the emulated environment (in a text editor, for instance).

Typing numbers for instance (the upper ones, on top of letters, not the ones from the numpad) produce symbols not related to my layout.

How can I configure BasiliskII (Mac emulator) to use the right layout of my keyboard ?
