Last view: 951 days 		If you have a VROM page in your expanded CHR-ROM that has passed #$FF, how do you use it, if you can?

I have reached the limit in my hack, so I want to know if it can be done. In other words, how do I store a value if it is passed FF?

The page I want is probably something like FF + 0A in my CHR space. So I have to add those two. I tried using ADC and AND, but those don't do anything. They just start counting from 0 after FF.
