MAME has a built in cheat function, think Game Genie for the arcade. With this you can make the game easier, and sometimes do things you are not supposed to do otehrwise. I haven't messed with the cheats in years, so this may be old news to most of you. I actually made some early cheats for MK2 back when the cheat engine was fairly new. It's been a while, but here are some fun cheats that are known now.
