There arn't many places that sell SD cards in my area. I guess i can get a 2GB card off of eBay or somthing, anyway in Nintendorks report on VC game storage it showed you can fit a hell of alot of VC games into that 521Mb space. I'll maybe just wait untill that space is full untill i invest in an SD card for my Wii. Its like what i did for my GC and other systems that use a memory card, just wait untill its full and then replace it
