Last night while we were all enjoying the glory that is Hackers, I hacked together this quick DTMF tone generator for GBA. I’ll post the source soon, you can have the ROM now. It doesn’t sound quite right to me, but I’ll put it to the test today and see if I can drive a payphone with it. I plan to use some telephone tones in one of my upcoming demo routines.
hi, i was wondering would this work on any other electronic devices. also how did you write this program as i am interested in that kind of thing?
