Since there is no way to raise feature requests for MAME I am posting this here. Hope that is OK.
Modern touchscreen devices do not emulate the mouse and operate as a tablet under windows. MAME currently does not recognise input from it either using DirecInput or RAW input. Under directinput movement is detected but not clicks/taps.
Just wanted to raise this and hopefully support can be considered to be added in the future.
Alternativly wondered what code changes would be required to work round it.
Thanks. Tom.
EDIT: PS: Talking about PCs not phones. ie Full Windows 7 x64 for PCs.
