The Nintendo DSi is now available in the USA and it seems like the flash cards didn't take much time to follow. There are now 4 flash cards that work with the Nintendo DSi: R4DSi, DSTTi, Ez Flash Vi and Acekard 2i. If you're a lucky owner of a DSi and need a flash card that will work with it, you now have your choice of 4 really good cards. The R4 seems to be the most popular card for the DS and it'll probably be a big hit with the DSi. We found a company that is carrying all of them, you can check them out here:
