Description

Hey there, I tried this assembler before, and it has improved from the days of old where it had no INCBIN, now it has INCBIN... So proud, But that is not why I am here...

Ever since new processor options came built-in to this assembler, hoping for someone to add 65(c)816 support to the latest version. with complete opcode support. used in the SNES, Apple ][GS, and the Commodore 64, as well as some homebrew experiments.

Can it really be supported?

Research direction

Start by reviewing DASM's existing processor support and how opcode sets are represented. Determine the full scope of 65816 support, including the processor's 16-bit behavior and opcode coverage. Done means DASM can assemble the complete 65816 instruction set reliably.
