Pinball 2000: Revenge From Mars (1.80 unofficial MOD)

From the PinMAME source:

1.70/1.80 is Tom Uban's (maybe with Lyman Sheats), i.e. the original
   Pinball 2000 programmers, for the EPC 2006 tournament server. The only readable strings it adds
   over 1.60 are a card-swipe tournament client ("Swipe card to play.", divisions, qualified
   players, "Server not responding...") - no gameplay change at all. 1.80 is also the one version wanting 8 MB of SDRAM, sitting on a white screen
   without it; nothing else needs it, and it cannot reach this driver anyway, which always just maps 256 MB.
