THanks a lot, that makes a lot of sense. I hadn't heard of relative branching before this but now I understand.

I've noticed when disassembling some roms that when they do the wait for vblank they'll say BPL $FB. But what does the $FB stand for? Cause I've seen it used like so:

LDX #$12
LDA #$00
STA $00,X
INX
BNE $FB

Which is obviously supposed to be a loop. Can anyone explain this to me?

Thanks
