If 2 light pens/guns enabled and if gun 2 moves, enable only gun 2 crosshair. Interestingly, the Mac boot disk I have is too old to be 32-bit compatible, so while it “sees” the full 9 megs of RAM in the Amiga, it can only access 512k of it. On screen led floppy leds have brighter border if inserted disk is write protected.

This setup literally connects two Apple Macintosh ROM chips (from a Mac Plus, in this instance) to the Amiga’s floppy drive, and via some unholy alliance of A-Max controller software + Apple ROM code + the Motorola 68000 CPU in the Amiga (the same chip that powered all the early Macs), this is a “hardware” emulation system.

Worth noting that this is not “software emulation” like how you might run Mini vMac on a modern computer. It was all accomplished with an old retail app called Amx, “the Macintosh emulator for your Amiga.” The hacker explains: Instead, it’s a weird Frankenstein project, in which a vintage Mac’s ROM chips have been connected to an Amiga’s Motorola 68000 processor, which was the same CPU in the Macs back then. So what we’re looking at here isn’t really emulation. Nor could you see a vintage Mac emulate a vintage PC at full speed: it just doesn’t have the bandwidth to “pretend” to be another system. You could never, say, use an Xbox One to emulate a Wii U at full speed. At the same time, though, this means you can only emulate systems older than current hardware.
