Oho, the upcoming tetris compilation has more versions now
So I wrote a bit ago about Tetris Forever, mostly a critique of the games list. Anyway, it's EXPANDED! Apparently they're including the Spectrum Holobyte DOS version as well as the original AcademySoft DOS version. I guess the holdup was that Digital Eclipse didn't have a DOS emulator before. I'll be interested to see what the museum mode covers in the end.
