Hi can you please share your game shark code ?

The corruption is not the fault of the cheat code, in fact, the UI does a refresh when the life reaches 0, just to free the VRAM and avoid reprinting sprites, the cheat code prevents the game from doing that refresh just for not reaching 0. xD
If you are looking to be invincible, try this GameShark Code: 010199CB
It works for v.1.2.0E
