This forum is for posting M.A.M.E. Work In Progress "Arcade"cheats that are not quite ready for the prime time. If the cheats are buggy or the cheat descriptions are non-standard then please post them here. Help maybe given but there are no guarantees and they will only be added to the cheat file when the cheat file maintainer is happy with them.
