Below are the .gb and .pocket files for Cuphead!
Cycle through screens with [right/a] to go forward, or [left/b] to go back.
The .gb file should work with any Gameboy emulator.
The .pocket file is for the Analogue pocket, and is untested due to not owning one but thought it would be nice to throw in for anyone who has one!
Enjoy the Funfair Fever rendition by Spagdev!
