FWIW here's the levels that are converts:
Taxing 13 = Crazy 1
Taxing 14 = Crazy 3
Taxing 17 = Crazy 14
Taxing 24 = Crazy 6
Taxing 25 = Crazy 10
Mayhem 10 = Crazy 2
Mayhem 28 = Crazy 15
Present 11 = Crazy 5
Sunsoft 15 = Crazy 7
So it looks like 9 were converted to ONML, all are in the Crazy set, and even the Sega designers grossly underestimated how hard Crazy 10 is
