mspactwin - Ms Pac Man Twin (Argentina)
 
概 要P1はP2のみのゲームで元気になる。
詳 細P1 springs to life in a P2-only game.
再現手順Reproduce:
1: start a p2 game
2: eat power pellet
3: as the pellet sound plays, move p1's controlls around (U,D,L,R)
Result:
P1 will spring to life, most of the time trapped up top or bottom of the screen, but sometimes she breaks out onto the maze.

This could be a game-bug (aka BTANB), but I have my doubts as too often someone would come up and start fiddling with the inactive player's controlls, at least, from what I remember back in the day... I'm sure they tested for that.
I think it's probable that there is some sort of mask(multiplexor?) that selectively enables the inputs. I didn't investigate that though.
追加情報Curiously, the green "18" at the bottom left of the titlescreen is a "0" on the pcb video from Roberto Fresca, maybe a clue?
video can be found @ https://robbie.mameworld.info/ "MS PACMAN TWIN" link, bottom of page.
