Re: Issues with STA at addresses greater than $8000
Yeah exactly, I was talking about that declaration - .segment "OAM" oam: .res 256 Not sure why I said 32 bytes, weird. My solution was this - LoadSprites: LDX #$00 LoadSpritesLoop: LDA sprites, x STA $0200, x INX CPX #$10 BNE LoadSpritesLoop I did change the above though in favor of the OA...

I am currently working on compression for my MetaTiles. I need lookup tables that start with a lowbyte $00. To a...
