I found a fork of MBF called MBF_SMN (by Sakitoshi) on github: https://github.com/Sakitoshi/mbf_sigil . The explicit goal seems to be to add support for Sigil (and some other wads) on top of MBF 2.04. I wanted to use MBF on DOS to play Sigil II so I hacked on some patches on top of it to support it …

If I'm not mistaken, stereo output of DB50XG is reversed; as well as WaveBlaster connector channels of the reference YMF71x sound cards. Thus taken together, they should sound properly.

That sure is a dramatic and valid excuse for losing things. Sorry to hear about that, also considering all the bigger real-life troubles that surely came with it. I can hear it. It sounds like an issue with slow feeding of midi data from the game with midi driver. These are just things and I'm way …

I just tried and it seems like the issue is still the same. Are you able to replicate the issue using MIDI/MPU-401 music? I'm not sure if it's a missing note or it's hitching but it happens a few times in those first couple of seconds. It's less obvious when listening to a Sound Canvas but all my …

Yeah, latest fdoomt50.exe(and 52 too) flickers like crazy in DosBox, in every build and fork I tested. But since it's working fine on almost every real video card, not a big deal I guess? Interestingly, there's no such issue in DosBox-X. Speaking about 'real' video cards, fdoom50 / 52 are also not …

Oh, yes, I checked for IRQ conflicts, both by making sure that the RAID controller and Audigy are in slots that don't share IRQs when automatically assigned, and then also by manually assigning their IRQs in BIOS. Unfortunately it didn't seem to help. I were struggling with similiar RAID/sound …
