Notes
After some reserch I can say that it's a genuine bootleg of Ms pacman by Orca and not an original board hacked to run mspacman.
The pcb is marked on the upper board OVG53A and has the typical symbol of this manufacturer and on the bottom board is marked OVG52A.
After looking on this site http://users.erols.com/mowerman/pacfile.htm I saw the AICA puckman bootleg is identical in layout to the Orca bootleg
(orca uses less eproms because they are 2732). Orca piggyback is the "Sex change" piggyback , it has the same TTLs and Z80.
The bottom board is identical to the PAC2 board.
Pinout matches the pac1/2 bootleg which in turn is the same as various Orca original games.
Since Orca made a bootleg of Crazykong, I think this should be included in mame.
The pcb works perfectly except the amplifier is burnt, the music/sounds are ok (I tried amplified speakers and it's ok).
