Could you point me to the VGM data does it not work correctly on? That way I'll have something to validate against when I have a large block of time to look into the issue. Thank you.

All tracks sound a little off at times. I suspect other tracks from games from the same developer will do the same. Also some tracks from Duke Nukem 2 hang the system completely

I can use the Cosmo Police to figure improve things. Since there are twenty of them, do you mind telling me which Duke Nukem 2 tracks cause your system to hang? I'll try to look at these as soon as I can. Thank you.

Some OPL2 rips, including Duke II and Alone in the Dark are known to hang on certain VGM players as the rips use the "opl2 wait" command. I don't know technical details, but this was fixed in MAmidiMEmo by simply adding a function to ignore it.

I played through all the VGMs in Duke Nukem II and there was no crash. Sadly, I won't be able to analyze what the source of the problem is.

Oh darn it does in fact work but I need to bypass DOS=HIGH,UMB and after that track 05 from DN2 plays fine! 😮 But once I enter a filer (FILMTN) and play it from there then it plays a single note and crashes with EMM386 saying "EMM386 has detected error #12 in an application at memory address 7DE9:EB43.". Darn how I hate using MS-DOS sometimes...
