And now, for completeness, the Acorn Lemmings MODs.
The regular cycle has 18 instead of 17 tunes (#14 is the one unique to Acorn). And of course you have the 4 tunes for the special graphics levels. [Beast 1 and Beast 2 are
quite radically rearranged but still roughly recognizable practically new tunes (but using similar instruments and evoking similar mood), Menace is shortened, and Awesome is...well, something else entirely
]
One interesting thing about the Acorn Lemmings MODs is, since they are still just arrangements of the same tunes in all the other ports, we already know what the tunes should sound like in their full length. So it would be possible to extend the Acorn Lemmings MODs accordingly, remedying the complain about length for many of them. Maybe something I'd look into over the holidays.
