MiyooCFW

MiyooCFW (Code) is a custom firmware for BittBoy, PocketGo, PowKiddy V90-Q90-Q20 and third party handheld consoles. It is based on the buildroot build environment and loosely based on OpenDingux. While it is intended for the named less powerful handhelds, it packs a good and wide selection of emulators. Some tinkering with the BIOS files is required though, but no worries, most of that is covered below or in their Wiki

BIOS Files

MiyooCFW doesn't seem to have a centralized folder for putting BIOS files so it's a chore to prepare the card for running the provided emulators. Here's a try to help with finding the right ones and putting them in the right place.
