On page 23 of the attached pdf, it shows the addresses of the registers. How exactly do I find one of these specific registers with ponyprog? How exactly do I change the value? By the way, what I'm trying to do is get rid of "red push" and edge enhancement (among other things) on my crt rptv. I will be using an I2C cable connected to my TV from my computer. I know what values to change them to, but I just don't know how to get to the exact place (within ponyprog) where I change them. Any help would be greatly appreciated.

I believe that registers are not accessible through ponyprog. Morover, they bear meaningful values only during the run-time and can be changed by the program anytime, so there is no point in trying to change them. Instead, you might want to change the program to use the registers the way you need. Are you sure that "registers" is what you want to change anyway??
