So I downloaded a nightly and slapped SDL2.dll in my game folder. I'm assuming that's where it goes, anyway. The slapping was definitely a must. Fired up the launcher, was surprised to see actual names for my devices instead of "PC-joystick driver". I attempted to use vJoy because FSO won't be able to discern between the X and Y axes also present on the stick. My vJoy stick ID is #1, but FSO seems to completely ignore vJoy. It also refuses to accept button and axis inputs, and using the throttle (dual throttle, so a second axis) makes FSO think I'm pitching and rolling.
So uh... is this an actual issue or is it because Saitek is dumb? This is probably unreadable but I honestly don't know how to explain it better, at least initially.
