okay, some questions.
1.) is STA TIM64T some sort of timer?
2.) What does the STA mean?
3.) LDY #$08 ;how many scanlines is each block?
LDX #$17 ;number of blocks of data. LDY * LDX = 192!
Are these height and width values? I tried messing
around with them and ended up with some pretty strange stuff.
4.) Is JMP essentially just a goto?
5.) LDX PF0
What does this code do?
6.) In the values function, are all the .BYTE $00 code lines used to
store your graphics? How does this work?
7.) Crackers, didn't you say you had a small program that would
let you create graphics for the 2600 instead of having to use graph paper?
Well, if anyone can shed some light on these questions, I would be most
grateful. Thanks.
