I ran some versions of Space Invaders through Mame, which was requested a few pages back. Caveat being that all these shown are official conversions up to 1992. Space Invaders DX was released in the Arcades 1994, and the conversions from then on (e.g. SNES) tend to mimic features of it or include the original as sort of bonus to otherwise beefed up versions, which is why a draw line there.

PC-98: Alt mode. Interestingly, there's also a Parody mode like in Space Invaders DX, but it doesn't resemble the Arcade.
