Not for DS users
The DS save backup doesn't work for many games, certainly not worth it if that is why you want this product. The GBA code side works fine.

Very Dissatisfied
Although the name suggest it's an action replay for both ds games and gba games. It is only an ar for gba games and a back up file saver for ds games.

alsome!!!
this thing is the best thing in the world i have ever seen.

Looks good
I think its a good product. 1 good thing is u can download ac:ww map editor and use this to edit animal crossing wild world saves!

Pretty good
Oh and umm aaron all u need to do is hook it up to ur computer and use the reset feature (all codes will be gone)
