I wonder why >it works on the emulators though. Maybe their "Branch >out of reach" is one byte more tolerant than a real >6507?!? Heh, you know what bugs me about DASM? That DASM doesn't mind assembling this: ZeroPageVariable EQU $80 lda ZeroPageVariable,y This should be an illegal address mode error! Instead it assumes: lda $0080,y This was one my biggest "gotchas" switching over from a CPU like 6809 where x and y are much more interchangeable. At least when I'd drop in a memonic like CMPX or ADDA I'd get an error but DASM is more than happy to assemble illegal zeropage,y as absolute,y commands. Grumble, grumble. Otherwise I'm having a great day though!
