Is something like this even possible? Essentially, I have a US Smash cart and want to play it on my JPN N3ds running emunand 9.5. I can't access the save data on the cart because it has been used with the update before. Being on a JPN N3DS, I'm also unable to download the update from the eshop (Though I tried getting the Japanese Smash update, but it didn't work), and since I'm in Classic mode, an installed .cia wouldn't work with my retail cart.
Any ideas?
