For this project I took a faulty Gameboy and removed the original circuit boards and replaced them with a cheap 3.5" lcd display and a Hackvision monochrome TV video game circuit consisting of an ATMEGA328P and a few passive components.
Detials of the Hackvision can be found on the internet.
I used 2 rechargable 3.7v lithium batteries in series as the power source (7.4v) which was enough to power the LCD and used the Gamesboy's original 5v voltage regulator to convert the 7.4v down to 5v for running the ATMEGA circuit.
