I have added many directives, such as .org, ines header, .dw, .bytes, and made it produce proper Roms launch into the entry point at 0xC000 from the reset vector. I basically rewrote the Assembler class, this could still use some cleaning up though, more unit tests, and to compile some code with CHR segments 2015-02-18 11:05:18 +00:00
