I think this is a strange video mode (possibly X mode
0x13 or the like) that 3D Realms Wacky Wheels
Basically the game hangs after the first introduction
screen, then when I press Alt+Tab and then Alt+Tab
again (to switch from and then back to Wacky Wheels)
then I hear the Wacky Wheels music and sound effects
(on its main-menu screen), but no video; in-fact, my
monitor reports: "Unusable Signal".
I downloaded the FreeDOS for a change of pace and the
graphics work fine without a hitch, but the sound doesn't
work under FreeDOS (obviously), so therefore DosBOX
is the best candidate to run Wacky Wheels.
