Hi there, I've been curious about this too. I hadn't run across any in the games I've disassembled. > I think AirLock (by Data Age?) used one... I looked at this and I think it uses one by accident. It does a jmp to LF01F which would cause the sax (opcode $83) instruction to be called. They could have jmp'd to LF021 (which is the Veritcal Sync routine) which would have bypassed this and the game would have worked the same. Take care, Dennis Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://stella.biglist.com
