Quote from: Midnightas on December 30, 2018, 10:24:55 amSlight additional question, if I may, but if I wanted to add the ability to draw transparent sprites, I'm assuming I'll have to lose the ldir instruction?One way I see going about this is to use ldi in a loop instead (which checks if it's equal to some "transparent" value).
