Seen on Odroid's forum (there also), there is finally an Amstrad CPC emulator for Odroid Go by Millim : CapriceESP32 !
You must put the directory /cpc at the base of the SD card (especially /cpc/dsk), the .FW will be in /odroid/firmware as usual.
I recommand to read the documentation of CapriceESP32. You must use the Menu key + B to access the .DSK directory then Menu + right arrow to go to the file list, select file with A, press Menu + B once again to launch the selected file. To use the virtual keyboard, press Menu + A and once again to remove it. There is no sound mute at the moment. If you want to reset the emulator, just choose another disk and file to execute.
