I have a weird IPAC2 issue I cannot track down and looking for some help, on Big Box or Devilblade reboot games, i get constant scrolling or mouse input moving the mouse up left. Below is what I have checked so far and also talked to Andy, but we didn't figure anything out.
I have the IPAC2 in keyboard mode and if I open Notepad or anything just in windows I get no indication that any of the arrow keys are being pressed and can freely use the joystick to scroll normally. If I remove all inputs from my arcade cabinet to the IPAC2, it still continues. Keyboard Test showed no input, Eventghost showed no inputs. No errors showing on teh IPAC, on the lastest multimode firmware.
If I unplug the ipac2, the scrolling stops during the apps affected. If I change to DirectInput mode it stops as well.
No scrolling seems to occur on other list based things that scroll using arrow keys, such as steam library, webpages, etc. Only when I open certain full screen apps. BigBox and DevilBlade reboot, but not KOFXIII in FS mode.
I checked usb game controllers to see if I may also be getting a game controller input even though I am in KB mode, but see nothing listed there. BUT, I disabled controller support in Big Box and it no longer scrolls, so I feel it is something to do with a stick\pad command being sent since that is what controller support uses in bigbox.
I disabled xbox gamebar, steam input, bluetooth.
I hooked the ipac2 up to my laptop and launched devil blade and had no scrolling, so it must be something on my arcade pc that is interacting with the IPAC2.
Looking for something else to test or try to capture the input that is causing issue. The Arcade PC is running Windows 10 in test mode for Groovymame and CRT EMU drivers and basically a fully fresh install outside of some game programs, no joy to key software or similar installed.
