Hey Tobias, I think I may have found something ... tell me if I'm on the right track here or not...
All of the memory between 50000000 - 50f001f0 is set to 8A8A 8A8A 8A8A 8A8A 8A8A 8A8A 8A8A 8A8A Then the mem between 50f00200 -50F003F0 is set to A0A0 A0A0 A0A0 A0A0 ... Then 50f00400 - 50f005e0 is 8080 ... 50f00600 - 50f007e0 2828 ... Then things start to get really interesting, and there seems to be some data stored in registers 50f00800 - 50f009f0 (and it changes everytime i check it with dp) 50f00a00 - seem to be uniform per line of output, but changte each time i check dp. Am I looking at the right registers here? How can you tell?
