I haven't been able to get my hands on one, though I haven't really tried that hard. I have played most games on it to death either through emulators, VC, original SNES, or all of the above.
I haven't actually played through Secret of Mana but I have played through it's sequel that never got a localization, Seiken Densetsu 3, which is a pretty darn good game. I was actually tempted to download the Secret of Mana collection off of the Japanese eshop for the Switch so I could play the game legit on a console for once.
