You might want to check out the Digital Leisure commercial version. I know the Space Ace CD makes you repeat the scenes. Not sure about DL though, but like Brian said thats how it was in the arcades. Actually I know here in the UK, there was a version in the arcades, where i think the scenes were sequential, not sure if you could repeat them though. I think it was by Imaginara. The other version was Atari which was more popular. Interestingly the Imaginara version had an led to display the score, while the atari showed on the monitor. Also the timing of the moves were slightly different making the game harder.
