I just recently started playing with ePSXe, and I'll have to say it's damn nice. Only problem I have (which I don't with other emulators) is that my joystick is VERY sensitive in ePSXe. I tried OmniJoy, but it didn't seem to work well, padJoy works but a tiny tap of the d-pad on my Gravis Xterminator, or a sporadic movement from it (sometimes it'll send off a move of like 2-5 points, it doesn't stay 0 all the time) will make a move in the game, which is very annoying. I have tried running jscal and saving the settings it gives me, but it still is way too sensitive. I can confirm that this doesn't happen in ZSNES nor Mupen64.
Any help would be greatly appreciated
