how about just playing the game in scummvm and recording the sound? can't be to hard... try Audacity or some other freeware audiosequencer.. could do it for you, but i don't think i have a copy of zac at the moment
Thanks for the suggestion - I'll do that. After posting that message I remembered that some of the sounds were generated in code, so there may not be any wav files to rip anyway. I'll fire up the game and get Audacity running.
