Some folks claim that the NES version of Marble Madness is the best home port. I can't possibly comment on that, as my remit is purely the 8-bit micros.

And on those, I can safely say that the #C64 wins. It is the only port that actually attempts to convert the coin-op. It's not bad either. Not great, not terrible.

The #Spectrum and #Amstrad, on the other hand, got something else. Something slow, painful and annoying. With a construction kit...

Play #Spindizzy instead.
