This is Kris's Assembler for the K64.

There is a companion 6502 emulator in the works called k6502.

Goals

• Implement the WDC 6502 instruction set -- using the WDC6502 datasheet
• Provide basic assembler directives

I'll know when this is done because I'll be able to assemble Microchess and it'll be byte for byte identical to ca65 or vasm.

Non-goals

• Implement macros

Warning

I do not know Rust, and I don't know how to build an assembler. This is probably not the code you're looking for.

Assembler completeness

Directives

Directive	Implemented	Notes
.ascii	partial	The scanner probably handles ;'s poorly
.bytes	complete
.equ	partial	Only hands $1234 words, and will panic on bad input
.org	partial	Requires zp: to be prefixed to zeropage labels

Instructions

• All instructions are believed to work, but some tests remain.

Command line options

Option	Description
-o <output_filename>	Override the default filename a.out
-s <size>	Size in bytes of the desired binary file
-p <padding>	Size in bytes of initial padding in binary file
