I was thinkin about it, I'm not gonna bother with a zDoom patch, for a couple of reasons...
1: The whole reason I thought about it was to use addons in the shareware version of doom (and get out of buying it). However, a good friend lent me a copy of Doom II, so no reason for zDoom.
2: Most of the features of zDoom (looking up/down, ect) can't be mapped with the few buttons of most mp3s.
