This is to just begin the start of CX16/Commander X16 dev time, with a better, simpler, Assembler, DASM is here for this, Just needs a 65c02 mode, as the Commander X16 uses a 65C02 for the CPU, and uses the VERA chip (open style VIC/PPU like graphics processor)...

We are focusing on that CPU on this system, and many more projects using the 65c02... This is just an "generic, extended 6502" meant to be the middle brother of the baby brother, the "original 6502", and the big brother, the "65816"... That is what the 65c02 is there in a nutshell.

Can you help get the 65c02 support, please? I know it takes some time and I am patient, Patience is a virtue...

Thank you very much!

Looks like it's already implemented?
