I tried your solution, and it worked! Thank you, tokumaru! I'll see if there is a better solution than having the same four lines twice. I could make it only update the TIA every four scanlines, but I don't really feel like doing that. I want to make a static effect for this, that was the original idea, but I got hung up on the playfield 'cause I'm a noob and haven't done this in a while.

That seems like a good solution. I'll try it out. One of them is before the frame starts, one is during the actual picture drawing before the next scanline, to prepare for drawing the next scanline. Having it during the hblank on that scanline itself I think takes up too many cycles.

Sorry for confusion, but that is actually the amount of scanlines in the TV frame, I have it decrementing down as I loop through the scanlines. Also, I am very very sorry for this late response. :\

This is probably a stupid mistake, but I can't figure out what I'm doing wrong. I'm just trying to draw the Atari logo on the playfield. The bitmap is 31 lines long, but I'm using LSR twice before loading it so it is the same for four scanlines. Here is my code for looping through the scanlines: ldy #191 tya lsr lsr tax ScanLoop lda PFData2,X sta PF2 lda PFData1,X sta PF1 sta WSYNC tya lsr lsr tax dey bne ScanLoop And I get something that looks like this: Thanks in advance, I don't know where I messed up here. Edit: Woops, that whole four lines of "tya lsr lsr tax" was meant to go after the DEY. I don't think that was causing it lol.
