- 0.33b2: Keith Wilkins added Slap Fight (Taito 1986) and clones (Japanese Bootleg) and (English Bootleg). Due to protection, the original version doesn't work. Scrolling is jerky. Music tempo is too slow. Use one of the bootlegs instead. The three games are identical, only the 1st CPU EPROM is different which shows up in the boot message, one if Japanese domestic and the other is English. The proms which MAY be the original slapfight ones currently give a hardware error and fail to boot.
