Game Genie Good Guy is based on Game Genie Guy (https://www.romhacking.net/utilities/1054/) but it is for Linux.

Can generate a patched ROM with inserted the Game Genie codes or the IPS patch to share, maybe else on this portal.

It is a CLI tool and include also a GUI version, to get more information check the readme that is more updated https://github.com/Mte90/Game-Genie-Good-Guy
