i dl 1456 - Zelda Phantom Hourglass (U)(iND).nds and i tried to play it but my r4 cant read it. help please!

have you already tried going to the options and changing the NDS cartridge backup media to FLASH 512 KBytes?

He's using an R4, not an emulator. Did you extract the ROM from the RAR or 7z archive?
