Research direction

No file or test is named. Reproduce the issue using Core Options > Touch Mode > Auto or Pointer on the listed platforms, then trace how mouse movement and left-button input are passed to the nooDS and melonDS DS cores. Done means the pointer moves and left-click registers as stylus input in both modes.
