What's this doing in Classic>Computer? *shuffles it over to Classic*

Also, I wouldn't say that clones like SupaBoy are any better with emulation than something like a Dingoo or GP2X despite the fact that they work with real SNES cartridges. You'll still find shortcomings that will put them squarely outside of the "perfect" category.

You could always contract a custom modder to build you a portable SNES Ben Heck style. Expensive yes, but 100% "perfect" based on the fact that it's the real deal.
