Random Gameboy Game Genie Codes
I have decided not to include most of the Galoob codes because these are just a sampling of some random stuff I had.
Though you can change them a bit like theses ones for Castlevania Adventure
0X5-5CF-C42 -Start with X Energy Bars
0X9-B3F-A26 -Start with X:15 time in Stage 1
Replace X with whatever you want.
Those codes aside, I only decided to post a few that I had laying around.
