Hugo is having some Endian issues AFAIK, and nobody checked it out about fixing it.
As to tgemu AFAIK the author was working on a new version which should add CD-Support, but never
released it (I was in email contact with him as
I did a WarpOS-port and later a - no sound yet -
OS 4 port of tgemu). Hmmm, maybe I should request
the Source-code for the sound-stuff from the
MOS-version, it is GPL after all
