Well nothing DS related uses a Memory Stick (i.e the sony designed memory card) you can use however, Compact Flash and all the varients of Secure Digital (normal, mini, micro) use card adpaters for the DS. There are various adapters, first that come to mind are the M3, the EZIV and the Supercard (in order in how good they are) I have an M3CF and a G6 Lite (the G6 uses inbuilt memory) It's a shame nothing utilises the Memory Stick format as i have tons of them, mainly for my 1.5 PSP, but also some for my Sony Ericsson phone and Sony Clie PDA - seems only sony devices use them, which isn't all that surprising.
