Okay, my dad got me an R4i 3DS for christmas, and I immediately started looking for a Super Mario 3D land rom. I found one, and put it on my 3DS. However, it won't even show up on the list of available games. It IS a .3ds file, so I would think that a 3DS flashcart would be able to read that. If the game just didn't load that would be one thing... I tried changing the file extension to .nds, and it showed up on the list, but wouldn't load. I have downloaded what I think is the latest firmware.
