I don't quite understand what you mean. Why would you want to run a non-glide DOS game under Glidos?

Simple. Better renderer. Most DOS games are software, whereas Glidos would render them on OpenGL or Direct3D.

Oh right. Ok. It would require a much more complete VESA implementation, and VGA for other games. It's more the sort of thing I should do with VDos32.

Make sure everyone can run this, when you manage to do it. I mean, I remember you said vdos32 will be mainly for Vista and Glidos is for 2000 / XP.
So far vdos32 seems to run fine on XP, but don't forget this 😀
