you can't simply rip this altered Klaewer_Oliver/Zero_Gravity.sid due to the antirip check described below =) you have to remove it THEN sidknown can play all the tune and identify it, anyway you can always try to check the crunched prg with option -b
This is another missing crack (Cybernoid2+/RSi), plus this intro crashes for some reason after a while.
If no good version of this will show up I can always replace with the same intro from another, existing, RSI release.
