Trying to use UniVBE to allow for VESA resolutions in Duke 3D like 320x400 but not having any luck. I’ve tried on a few cards like a Tseng 6000 and now a Matrox Mystique as shown below. Any ideas?

So you don't like VESA 640x480 or 800x600?
For Matrox Mystique, IIRC it requires a supplement VESA TSR to support low-res VESA modes. Typically, UniVBE is not required for Matrox Mystique but I don't remember if it will supplement low-res VESA modes for Matrox Mystique. UniVBE comes with VBETEST which you can use to check if the low-res VESA mode used by the game is available.

Sometimes I like to play on slower machines and find it to be a good compromise. It works on a Riva 128 without UniVBE but really curious how to get it working on some of these other cards I have. I thought UniVBE would be the answer but maybe I’m not setting it up correctly or as you mentioned need a TSR?
Just use VBETEST that comes with UniVBE to list the VESA modes. You can use it with or without UniVBE. If the low-res VESA modes showed up, then the game will work.
Some companies believed VBIOS resident memory footprint can be as large as 64KiB, some didn't just to be 100% IBM PC AT compatible. So they would have to trim the fonts & video modes table to fit the main VBIOS into 32KiB and the rest in VBIOS supplement TSR. I know Matrox Mystique has VBIOS supplement TSR, but I am not quite sure if it will offer low-res VESA modes. Some companies also decided that low-res VESA modes were not worthy of support. Most games would just use VGA mode 13h or mode-X, so the design would prioritize hi-res VESA modes starting at 640x400.
Any ideas?
Use older UniVBE version. 6.70 dropped some lowres modes (at least without additional configuring).
I must be some kind of standard: the anonymous gangbanger of the 21st century.
