Ok, since these can seemingly be useful on the Atari 2600 platform at the very least, does anyone know what they all are? Perhaps a website dedicated to the 6502 has a complete list. I'm assuming that the other 100 or so illegal opcodes aren't all 'LAX'. This sounds like a great way to save cycles, and sounds like another one of those neat "programming tricks". Perhaps some ROMs already use illegal opcodes, and that prevents their full working on certain emulators. Has anyone ever encountered illegal opcodes in a disassembly project? -John K.
