I just finished my first Atari 2600 game (I just need to finalize some of the different game settings and come up with a name for it). I don't have any plans to try to sell it, I just want people to enjoy it. What's the best way to make this available?

I am experimenting with sprites, and I have a simple two-line kernel. Every even-numbered scanline should show a solid red line (#255), while every odd-numbered scanline should show a dotted (#170) yellow line. I want to use GRP0 for both odd and even lines. Nothing I have tried works, and for the life of me, I can't figure out why. Here is my kernel: NextFrame VERTICAL_SYNC TIMER_SETUP 37 lda #$70 sta COLUBK lda #0 sta VDELP0 lda #0 sta GRP0 sta GRP1 TIMER_WAIT ldx #192 LVScan txa and #$01 beq .oddscan .evenscan lda #$48 ;red sta COLUP0 lda #255 sta GRP0 sta RESP0 jmp .join .oddscan lda #$1e ;yellow sta COLUP0 lda #170 sta GRP0 sta RESP0 .join sta WSYNC dex bne LVScan ; 30 lines of overscan TIMER_SETUP 32 lda #170 sta GRP0 TIMER_WAIT jmp NextFrame Any idea what the problem is? Thanks!
