😁..... Here is my issue and why I asked it the way that I did, as sometimes technical questions aren't understood appropriately on the board. I have RS3 Reaper Guns setup in Mouse+Keyboard config and by default the Trigger is translated as left mouse click, thumb button is right mouse click, and bottom(clip) button is middle mouse click. (No App to change any functions, just dip switches). I have the gun games setup on Lightgun mode and I prefer to use the thumb button for reloading. By default, the thumb button (right click)(reload) works great for reloading except that it vibrates the rumble motor every time it is pushed, which to me is annoying so the only option the gun has is a dipswitch to turn off the motor vibration permanently. This fixes the problem for the motor rumbling when pushing the thumb button, however, when using hooking apps, like Hook of the Reaper, the motor does not work when getting hit because it has been disabled by the dipswitch. The gun has a function of swapping the thumb button so that it becomes the middle button and the bottom(clip) button now becomes the right button. If I turn the dipswitch back on, the rumble has moved to the bottom(clip) when pushed as it is now the default "Reload"(Right Mouse Click) and in emu's like Teknoparrot and MAME, I can set the reload button to the thumb button,(Now middle button) and there is no vibration when triggered and the hits from the hooking work great.
The problem of not being able to assign a button also happens in Sega Model 2 Emulator using Demulshooter and there is no workaround, so that's why I was asking in the case that there is some option that I am not aware of in Hypseus. 😉
