; Test file for base 6502 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.
