Here you can download .vkm files for Keymmodore or Pimmodore 64.

Remember:
- Your keyboard layout host system (PC, Raspberry, etc.) has to be set to «US» or «US International».
- You need to change the Keyboard configuration in the emulator to Positional (User) and use the .vkm files corresponding to each model of computer to emulate.
You can create /home/pi/Keymmodore-64 directory and put the files there. Go to Settings/Input devices/Keyboard, select «Positional (user)». Then browse and select the right .vkm file. Also remember to «Save Settings». (You can use WinSCP or any other SSH software to do it remotely).
Note 1: Due to some key mapping limitation in Combian emulator, using PET Graphics emulation, right graphics PETSCII of @,+,–,* and \ keys, won’t match C-64 keyboard, matching the original PET layout.
Note 2: These vkm files should work also with VICE version distributed in Retropie, you can find more info here.
