How would I go about getting a Gameboy colour emulator on my gameshell and be all Lee to load my roms from my collection??
Also is there a way to run emulation station on the shell as I have all the config des for that 
Retroarch has a core that will run game boy colour (look for it in the core download, it’s gambatte)
Also, there’s a thread around these parts which describe transplanting emulation station, but personally, I’d recommend loading retroarch cores as needed and following the guide here: How to add new emulators (Gameboy, SNES, etc.)
