syltefar.com: Marble Madness
Original developed by Atari
 Got the score 20540.
Reached the Arial Race. This is a pretty good port of a very classic game. I miss the shadows from the original, but I guess they couldn't fit it into the 128KB ROM.
 So many company names on this game! Copyright Tengen, that's just Atari under a different name, licensed by Nintendo of America, of course, presented by Milton Bradley (the board game company), a subsidiary of Hasbro. And the ROM itself has '(C) COPYRIGHT 1988 RARE LTD. ENGLAND', who I guess actually made this port.
