Reliable technical documentation for how these instructions are decoded is a little thin on the ground online, so some of this implementation is still speculative.

; Test file for 65C02 extended opcode compliance
|
|
; This odd little source file uses every addressing mode
|
|
; of every opcode, and uses the opcode itself as the argument
|
|
; to each instruction that takes one. The resulting binary's
|
|
; bytes are thus in strictly increasing numerical order.
|
|
|
|
; Some opcodes have multiple mnemonics; we provide both.
|
|
|
|
; This file also doesn't include the 65C02's opcodes that
|
|
; are also available in stock 6502s - see testbase.oph for
|
|
; those.
