Hi
I'm new to NES dev'n but far from a newbie when it comes to 65** ASM.
I got a question, when I set BIT3 of $2001 and enables the leftmost 8pixels of the screen to be shown there appears a 8x8 sprite (always tile 0 from the patterntable) in the left/topmost (0,0) corner on almost every emulator I run FCEultra, Nesticle, RockNES etc.. I've gone through my code, and there shouldn't be any bugs as far as I know.. Is this a common occurrance?
