I had been studying your Robot City source. That's where I saw you use
the $0C opcode. I was confused and went to look up the illegal 6502
opcodes. I saw that it went to skip the next word.

I would recommend to anyone trying to tighten up ROM usage or cycles to
visit or any
site similar.

Take care,
