Be sure to check out @calc84maniac's (the creator of the TIBoy CE emulator)'s channel as well! Without his work this obviously wouldn't be possible!
This video describes the process of installing and playing both Gameboy and Gameboy Color games on the TI84+ CE/TI83PCE (Python) calculators! It also will explain how to setup the required jailbreak on your calculator if it needs it.
