My old 3DS broke a while back but that 3DS was the one I started out my Ultimate NES Remix cart on. Because this is a different 3DS it won't send any times I get to the regional list or friend list even if I place top 10. Is there a way around this?

Only if you delete all of your save data by holding ABXY as the game starts

That really stinks.

All I got is a photo (which I can't even submit for proof) for my 6.9 run. I really don't want to reset my stuff because I put a lot of work into where I'm at right now.

Aanndd now a photo for my 6.6 WR!
