new clones
Gang Wars (Japan) [jets from emufrance and Layer from neo-arcadia]

(i've asked for the other roms in the set to be checked)

also reinstated the bootleg, these 68705 instead of alpha mcu bootlegs might be interesting later down the line even if the main code is the same..

also one of our mask roms was bad, and the gangwarsu set should definitely have been using different roms for the gfx
