Hi gbatempers! I'm playing with NDS Touch Screen Controller. Acording to Gbatek : Setting breakpoint to 0x040001C2, I succesfully retrieve the Control Byte and have a good understanding on how it works. However, I have no clue how to find the channels gbatek is talking about. The main purpose is just to set a breakpoint in no$gba dev whenever screen is touched (aka Ch5 and Ch1 values changed). Thanks for your help!
