I sell old Amiga games... the problem is getting hold of them in the first place. When I do sell them, though, I can usually put them on a CD if the buyer wants so they can play in WinUAE or whatever, but to be honest most people who buy the actual game just want to play it on their Amiga.
There's a different mindset for emulators, including UAE - a kind of "it's not the real thing so I shouldn't pay for it, and I don't need the box" kind of mindset. Generally if people want to play on emulators they're happy with a downloadable version, when they want to play on the real thing, they want the full boxed version.
In my experience, anyway. YMMV.
