I started doing GameShark codes back in 2005 for the PlayStation 2. Years later, I have added PlayStation 1, Nintendo, GameBoy, and now Sega Master System. I am trying to finish these up to do more systems. PlayStation 1 is not even done yet. I am doing work on more than one Console at a time, and there is a lot of work left to do.
PlayStation 1
PlayStation 2
Nintendo (NES)
GameBoy Codes
Sega Master System
Atari Linx
I am starting a Discord chat for fun and learning. It is only for game codes and not too much about hacking the game. Just code research and developement. It just got posted on 06/08/23. May take some time for others to join. Catch me on Discord
