Admittedly, any copy of the game you might get your hands on these days won't need the code wheel, but if, by some chance, you have an old 8-bit computer, a legit copy of the game...but have lost the code wheel, this could've been a great help. But no, this is a scan of the wheels (you get it, uploader?) in one position. If a person, having one of these wheels, wanted to provide something of actual value to someone as I described, they'd either disassemble the stack of three wheels, scan each one, and upload THAT. The other way, if you really don't want to disassemble the wheel-set, you could, instead, scan the stack as many times as it takes, with one setting for each scan.

I'd do this myself, if I had some idea of where my copy is. I have too much stuff, in too many boxes, to do this anytime soon, but, if I do find it, I'll do it, just so it's in the Archive.

Of course, if you've bought the game(s) from Good Old Games, like I've done (not to mention the 2005 set, with the new version of the game + all three of the old ones [the old ones included don't exactly run...]), you won't need the wheel, and you won't have to fiddle around with an emulator.
