Yes it may be rational explanation. DSDMA probably do some V86 magic. So you mean that when VME is used by JEMM then the v86-monitor run a bit different way that conflicts with DSDMA tampering approach while if VME is not used it do it correctly? The DSDMA.EXE is dated 13.5.1999 maybe that VME was not exist yet. Do you think it could be pathed to be VME compatible? Unfortunatelly no sources available. I can only run it through IDA DASM if you are interested in what it does. I didn't tried it with a realmode game as I don't remember one that use SB and run realmode.

BTW the TSR of Aureal Vortex ASP4DOS.COM doesn't require v86 mode but it also interfere with some pmode demos that hangs/crashes so it's not 100% SB emulation but for dos4gw games it seems to work well.
