Hello! Not sure if this is the right place but has anyone attempted to link up the original gameboy (or gameboy color) to an Arduino? I found a github where this person attempted it ( https://github.com/tomvdb/gameboy-arduino ), with it showing the pinouts, but I'm not certain there's anything else that needs to go in between it or it's just a straight up link cable wire to Arduino pins? (No resistors, etc). I don't want to attempt it if there's a chance of frying my only working gameboy Thank you!
It will be fine if both devices work on the same voltage. The Gameboy might be a 3.3V device, mixed voltage, or all 5V. You should start by checking out what voltage levels the link bus uses. An Arduino is commonly a 5V device but they can be made to run on 3.3V with modifications or special setup. What do you want to do with the Arduino attached?
Ahh good point, the plan is to use one of the gameboy communication samples to send and receive from the Arduino. There was some crafty guy who faked a gameboy for Pokemon Trading: https://www.geek.com/games/coder-us...with-himself-using-only-one-game-boy-1616170/ It would be nice to find a way to backup Pokemon saves, but there would need to be some sort of middleman between the Pokemon Cart and Gameboy (e.g gameshark / game genie )
