Have anyone here gotten SVGA mode to work in Tunnel B1? I've tested on several computers with different setups, and the option just won't show up in display settings. According to the readme the high-res option (640x480) will show up if you have a VESA compliant video card.
Maybe it was never implemented?
I did play the game in SVGA mode, but you require a fast Pentium 1 PC for that (there is also no 3D acceleration).
If the game detects a VESA compliant graphics card, then it should display the "High" resolution option in the "Display Options" menu.
You can perhaps try to load a VESA tsr (like UNIVBE) and then check if the game detects it.
EDIT: I just tested it now on my Celeron 900 with an ATI Radeon 8500 and it works fine in SVGA mode.
Yesterday i installed this game under DOSMode on WindowsME and it did detected my Voodoo4500 and allowed me to switch it to 640x480 (or High Quality as it appear on the option screen). The game ran pretty choppy though, with a significant FPS loss. I switched it to MEDIUM and ran beautifully
IIRC it intentionally wants a 640x480x16bpp mode which not a lot of cards could do then (especially for 1996).
Did you try it in DOSBox?
