Hi. I am what I believe you would call a "noob"— actually I have no time to learn any of this, I have six kids under eight including two sets of twins. I am trying to get the R4i V1.4 Revolution for DS (DSi/DSL/NDS) www.R4I-GOLD.COM flash carts to work in my kids' DSI XLs. I have hunted high and low but there is so much stuff out there I am not sure what to use. The cards look like this: I hope that worked, I tried to insert an image. Anywho, the DSi XLs will not run anything from the R4 cards. I NEED help. I am getting conflicting information as to whether this flash cart will work in the DSi at all. HELP! HELP! HELP! Thanks!
