Here's a fully reversed version of your STEEM snapshot, but I don't think it'll help rip the tune. The scroll text and display text might be stored in reverse to make it a bit more tricky to rip, but I don't know how STEEM snapshots are stored so I don't think the memory dump itself is reversed.
Do you have the standalone version of the demo or is it from the Froggies Over The Fence demo?
They don't have the standalone version on Demozoo.
frog.out (reversed version of the file you supplied)
Also attached is the C++ source code to reverse a whole file byte for byte. It loads the whole file into memory so be sensible.
The samples can be heard by loading the file into Audacity. The samples are Unsigned 8-bit PCM.
