Re: A86: djnz, jr and jp




I have a parallel link. I have assembly studio 86. I have made two
different styles of full tile-based maping systems and 2 rpg battle-style
systems. I have messed with graphics effects and string files. I'm just
trying to learn more about the way the z80 works. I don't plan on making
anything amazing or even half-decent. It's a learning thing. Besides, I'm
not the only person who would benefit from an on-calc assembler, which
seems quite simple to me at this point.
