No Salvation is original, not a remake. I just couldn't find a 100% solution myself, so I'd be pretty interested to see a replay. The intended solution doesn't require a blocker (although using one does help - but the grid alignment doesn't matter in this case, as it's only to help position a bomber).
I use Lemmix (original or ohno, whichever is applicable) with LookForLVLFiles to test, rather than the editor or CustLemm, so Not Gonna Work is definately possible with the original fall distance.
Clam: The bump in RotT was nessecary in the cheapo original, it simply stayed in the DOS port.
