Top Gun is responsive and seems playable, you can 'move around' and shoot, and hear the sound effects. G&W Mickey & Donald is using SM510 opcodes I don't fully understand and are documented differently across different SM510 series datasheets. It can mean either a mistake in the datasheet, or they differ between SM510 and SM511. (opcodes are: LB x and SBM)
Top Gun and M&D use the same cpu, and I suspect it's called a SM54C.
