Dosbox emulates glide, (voodoo 1)it doesn't need a voodoo card for that, at least that's what i make of it.
I don't think dosbox supports Voodoo 2.
Maybe it is better to set up a dedicated retro pc for that.
I am setting up a pentium 3 pc for that, with a Ati 9600 and a voodoo 2 (that is if i ever find the time).
