When I put rhythm paradise on my R4i, even though i only put one file on the MicroSD, (the nds file), the menu reads it as 2! I get the normal one and a second one with the same logo as Moonshell, and its only 4KB in size! Its not really important, buts its pissing me off, like a fly buzzing around my head... any help?
It's probably the save file. Check your settings to see if there is an option to hide save files, or hide unsupported file types, etc.
I toguht that aswell, I dont think its the save file because none of the others show... Mebbe unsupported, but then again, if you check it on a PC, it is just the game file and save file...
Try deleting it. Go to your R4, turn it on and press 'x' on the file and choose yes. After that, backup your stuff and format with Panasonic Formatter.
You should try emptying out your Micro SD card (backing up or simply deleting without making backups, it's your choice) as much as you can, formatting the card, and then putting everything back on there if it bugs you that much. By the way, can you see this duplicate file on your PC with 'show hidden files' activated, or is it only visible when you turn on your DS with your card inserted into slot-1? It sometimes means your card might be a little corrupted, or the NDS file you downloaded is a bit messed up.
