GradualGames Posted January 1, 2018 Share Posted January 1, 2018 When I do a sta WSYNC, does this cause the TIA to actually pause CPU execution until the beginning of a scanline...? Quote Link to comment Share on other sites More sharing options...
GradualGames Posted January 1, 2018 Author Share Posted January 1, 2018 (edited) When I do a sta WSYNC, does this cause the TIA to actually pause CPU execution until the beginning of a scanline...? NM, I see SPG says: "WSYNC (wait for sync) This address halts microporcessor by clearing RDY latch to zero. RDY is set true again by the leading edge of horizontal blank." That's actually kinda neat.

gauauu Posted January 3, 2018 Share Posted January 3, 2018 That's actually kinda neat. Yup. I really missed having this when I went from Atari to NES dev (the opposite of what you're doing!) Quote Link to comment Share on other sites More sharing options...
