It works now with DSP and shows 3D graphics, but I don't have any music.

Do you have music in it?


I tested many programs and only regression I
noticed was in Sidetracked music demo, it doesn't
anymore start, *even with older Hatari version*,
neither with TOS4 or EmuTOS, with or without MMU,
with Hatari default config or my own.

(Dry Egg game, which also worked only with EmuTOS,
does still work.)

I don't understand what could have changed, to
break that demo also with older Hatari versions.

Maybe it's wall clock sensitive?

PS. I'll push update to compatibility list &
release notes after I've done some additional
testing.
