its-a-feature

So I've been trying to figure out how to draw sprite in 6502... my main problem is that either it doesn't show the sprite at all, or if I'm trying to follow a tutorial it doesn't work since it's NTSC and I'm using PAL. I'm really confused as to how it works so if anyone could shed some light on it, that would be much appreciated.

That makes sense, and it works now... thank you!

Okay I tried to take that and implement it, but it's still not working... Is there something I'm missing? Here's my code... Kernel ldx #242 lda #$55 sta COLUPF LOOP cpx #49 bcs SKIP lda #%00100000 sta PF0 SKIP sta WSYNC dex bne LOOP rts

Hi, so I'm just getting into 6502 assembly programming, and I'm having a hard time figuring out how to edit PF1 mid scanline so that I can make an asymmetrical playfield. I was wondering if anybody could explain it to me, with code examples if possible. Also I'm on PAL, so I have 242 screenlines instead of 192.
