tobiasvl Posted November 15, 2019 Share Posted November 15, 2019 Hey, I'm new here, hope starting a new thread for this is OK. I'm working on a little Channel F project and I have a couple of questions so far, will probably have more over the next days/weeks as I encounter them... First off: Is there really no way to OR two registers? There's XS and NS for XOR and AND respectively, but no OR (AS can be used to OR one high and one low nibble though). I guess I can do OM which does an OR of A and the value at DC0, but in order to be able to use that for a non-hardcoded value I need to use Schach RAM to put the byte I need to OR with A? That sounds so extremely convoluted I almost can't believe it! But I can work with it, of course, unless there's another way. Second: I have about 300 lines of code so far but I haven't dared draw anything to the screen yet, hehe. Just so I understand this correctly, you draw per-pixel by saying what color the pixel should be. You set it to either red, blue, green or transparent. The background color is defined by the palette columns; if it's black, all colors except transparent are displayed as white instead. Does that sum it up? Thanks!
