I recently came across this Sega promotional video. It was bundled with the April 1993 issue of the Spanish gaming magazine "Hobby Consolas". There's tons of game footage in there, but the interesting part is the Sonic Spinball footage, at about 5 minutes, 32 seconds in. There are some major differences between the version shown in the video and the version we got. [youtube]http://www.youtube.com/watch?v=EL7hI24WZks#t=05m32s[/youtube] Obvious differences include: - Cutscene of Robotnik looking at his monitor as Sonic advances through the game, a la SegaSonic Arcade - Mobius loop in the Toxic Caves minecart - Different sprites on the wall of the steam room in Lava Powerhouse - Robo-boiler boss layout slightly different, background very different. It looks almost like it was originally going to be in The Machine Zone. - Different scoreboard graphics in the bonus stages And there are probably other differences that I didn't notice. Start video dissection immediately!
