I can't seem to figure out what this is. I know at one point I bought it at one point because I needed it for something but I can't really remember but I know it was important. It looks like a cartridge extender or something. I haven't seen it in about four years so I honestly can't remember. I tried searching on Google but I didn't have any luck. It sort of looks like an adapter but this is for the DS Lite so I don't know what it'd be adapting.
Edit: I did a search for ROM/flash cards and I can't seem to find anything thats what I have. Just R4 cards.
Edit: here's an image I found which appears to have what I have. It's apparently a ROM/homebrew thing. I do remember getting it at Gamestop so I don't know why I got it:
And here's what I have

Looks to be an Action Replay. You insert it into your system, and then a game into the Action Replay. Typically allows for cheating in games and copying save files.
Gamestop often sells them, whereas I've not seen them sell flash carts.
It looks very much like the Action Replay unit for DS and DS Lite: There's a Wikipedia article about the action replay series.
Looks like an adapter for microSD used for playing pirated or ROM dumped games.
