I get the impression from reading other threads that none of the gp2x gameboy emulators work with LittleSoundDJ. Most seem to run it but the audio doesn't work propperly.

Just for confirmation, do none of the emulators run this propperly?

Roll on LittleGPTracker!

I think most of the emulators are ported from the same source, I know improvements have been made but they're probably bery similar.
