Got one of the newer GUN4IR units from RPEG Electronics and it appears to work natively as a mouse in most cores, but the aim seems way off. When I try to calibrate it through F10, it only seems to register movement on the upper side of the screen and I can’t complete to process. In addition, if I try to add it as an input device (either general or core-specific), only the d-pad, select, and start are recognized: buttons A, B, and the bottom handle button seemingly don’t register. I’ve tried to see if there’s some guide specifically for using the GUN4IR on Mister, but I haven’t found anything. Is there some driver or config file I need to download? I know it isn’t the gun itself or the IR emitters, as they work with my PC just fine. Any help would be appreciated. TIA.
