do keep in mind that while the 65816 is pretty compatible with the 65C02 (even in native mode), making actual proper use of it's extended features like 16-bit registers and the 16MB memory range does require a lot of redesigning. it's the one reason why cc65 or llvm-6503 don't have a 65816 port yet.

Thanks for the info mate
cheers,
Paul

I recently updated my pas6502 Pascal -> 6502 compiler again. It now supports c64, c128, vic20, BBC micro, Atari 8-bit, and soon NES (hopefully).
