Chocobo Dungeon 2's PSF shell code (written by CaitSith 2, not the actual Squaresoft player) has an illegal MIPS code sequence[1] and relies on a bug in Highly Experimental's CPU core. smf has tested both the specific code sequence and the actual PSF converted to EXE on real hardware and both fail, so SexyPSF and PSFPlay are technically more accurate by refusing to play it. As Richard noted, AO plays it by detecting and patching the offending code [1] For the technically inclined, they put a J[ump] in the delay slot of a BNE. That's legal on some later MIPS CPUs which have more advanced interlocks, but on the PSX's CPU chaos ensues.

I haven't studied the problem in detail, but is the PSG ahead of the sample channels or vice-versa?

R. Belmont: The PSG is faster than the samples. Yes, faster; the tune starts off sounding OK, but the PSG and samples grow more and more out of synch as the tune plays on. I've been told this is a problem in the underlying Boycott Advance core, and indeed, game music in Boycott Advance seems to have the very same issue. Perhaps this could be remedied by changing to Visual Boy Advance 's sound emulation...

And another .sndh problem... MSG's soundtrack for the homebrew Atari version of Chu Chu Rocket plays perfectly fine in XSC , but seems to be missing, well, most of the instrumentation when played via Audio Overload. It's in snd10_lf.zip on the SndPlayer site , for the record.

don't use Sndh files from sndplayer.atari.org since many of them are directly converted from logged YM-files. To have an updated archive of SNDH music go to http://phf.atari.org its in the downlaod section... starting with Grazey's zak hacks #21 are the sndh files. Also there is an V2 of SNDH-format now

Now i checked with the newest AO and the reason why ChuChu Rocket sound bad is that AO dont play the Sid-voice effect.
btw: its the windows version i use... and it's still playing the sndh music in stereo, i find no mono option?

Sid-voice? Does the ST also have a PC speaker or something?

it's called "sid-voice" since the effect is similar to one of the waveforms from the commodore sid ;-)
