sound cpu: sharp LH0080A Z80A @ 4MHz 8705
this set shows "GF" (revision?) on title screen
this seems to be a bootleg of a prototype, not sure if it's the other proto set hacked or another rev proto
+ some of the tile roms are half size but the original has a lot of unused data so nothing is missing in game.
+ the various Mitsubishi custom chips present on original board are implemented with standard ttl chips:
+ MN50005XTA on the main board is 11 ttl chips
+ M60002-0118P on the video board is 27 ttl chips
+ MA7053 sil module on the main board is 4 ttl chips
+ these are all properly integrated into the design of the boards, not plug-in sub/daughter boards.
