All of the normal fixes, 2209patch, DDU, HEAP, HAD to use the WAC even though some don't with the dgVoodoo wrapper.
Gamepad was interesting since there was no yaw input on the pad so air to air was impossible without the invulnerable cheat.
When I was flying with the pad and with the stick with no profile I was constantly switching views and even rapidly running my finger back and forth across all the F keys like a piano, no fails, no CTDs.
