Thanks to @duncanyoyo1 for helping sort out the muxupd to get this connected. It has been working for me now!
I have been able to launch coco games via xroar when a bios is added to the applications/xroar/bios folder or:
/mnt/mmc/MUOS/bios/xroar
bas13.rom is an example of usable bios file for coco2 emulation
Game files should go in a folder named coco, but xroar should be able to be assigned manually if in a different location.
FYI if you see these images, the emulator loaded, but you need to add a bios file
The launch file is:
/opt/muos/script/launch/ext-xroar.sh
I have edited this launcher to allow custom gptk files that match the name of the game file if placed in: MUOS/application/xroar/gptk/
Rename this file to .muxupd to have it install and run the chmod script (I can’t upload a muxupd directly)
