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.
——-Castlevania Adventure (Gameboy)——-
134-6FD-CA0 -Stuff falls through the ground, includes enemies and items.

Put in different values for XX for different results

00-1B Normal Pieces, you will probably find these codes in other places

These Glitchy pieces are really strange. It’s hard to tell how large they are and they look like text from the game.
