Psp takes a pro duo memory stick. They do have adapters now to put one or two micro sd cards in though. I found those on ebay. The adapters are pretty cheap if you don't mind waiting a couple wks for delivery. Cheap as in less than $5 total. Also, on my psp spec it says it can use SDHC memory cards just for the record. bsus1412- go to google or whatever search engine you use and type in the handheld that you have and specs it should tell you everything you want to know about it. OR specifically look up "What memory card can I use with my..........?"
The regular sd memory cards work in some digital cameras, some laptops have a slot for them, things like kids tablets and some other things, but most newer things take micro sd now, like cell phones and other tablets. I hope this helps.
so the wii did recognize this then? I nodded mine as well and will be using an external hd for all my games but I'd like this for all my snes/sega Roms if the wii recognizes it as 16gb
