I bought an 8 GB SDHC card for my 3DS, which seems to be working just fine for saving things like pictures, but for some reason I noticed that DSiWare titles I purchased, downloaded to the system memory without even giving me a choice of picking the SD card. I went to the system settings and tried to copy the titles over to the card, but it tells me "If you copy this software to the SD card, you will be unable to launch it. Is this ok?".
So my question is, how do I set this up so I can run my games off the card? I heard there was a way, despite what the 3DS's message says. And the system memory is so very limited, It'll be full in no time if I can't figure this out.
