After trying several different PCI soundcards which claim
some level of ISA Sound Blaster compatibility, I can tell
you that your luck will also depend on how much ISA your
PCI mainboard still supports with special retro DMA etc.

So basically this only worked well for computers which were
only slightly too new to have ISA slots. After that, things
do indeed get ugly and success also varies from game to game.
But this most likely also happens with MS DOS.

None of the cards worked for more than non-DMA or OPL3 on
too new mainboards. Maybe SB PCI or SB Live would be the
exceptions. I have not tried those because those are known
to require protected mode drivers to simulate compatibility
in software instead of relying on mainboard hardware help.

The SB Live drivers may work better with MS EMM386, but the
drivers fail to work with specific games in the way they do
or do not cooperate in protected mode use in all DOS brands.

And the nicer protected mode SB16 simulation is DOSEMU2 or
DOSBOX, I think. Some "SB16 on HDA hardware" could be nice
to have in real DOS, but that has a bad balance between the
complexity and desire to have it if you have DOSBOX/DOSEMU.

In context of the above: Does the same happen if you do
NOT load the special PCI soundcard drivers? I would think
that the trio JEMM386 plus PCI sound plus protected mode
games is most evil, while real mode games and ISA or no
sound might be just fine with the same JEMM386. Of course
some daring command line options for JEMM386 are still a
source of stability risks. You are free to change those.

Please be more specific about how FreeDOS DOSFSCK fails
to repair FAT (FAT16? FAT32?) damage by crashing games
in situations where Linux (also with DOSFSCK?) fixes it.

Having crashes which cause FAT damage is really frustrating,
but I would have to know more details to think about which
repairs types FreeDOS repair tools (either CHKDSK or DOSFSCK)
fail to offer yet.

Regards, Eric
