Hi, I have a DS with R4 New super mario bros rom and my girlfriend has a DS with the original new super mario bros card when we try the download play it works fine.. but when we choose the option "play with a player who has the game" and then I create a group, it doesn't show on her DS when she clicks on join group.. any ideas what's wrong. My new super mario bros rom is 32mbs.. did i miss something?
possibly the rom is from a different region to your gf's. i.e. if your gf has US copy then make sure you have US rom etc. Just a guess but u never know.
yap my bad. I had the Euro ROM. thanks. i had no idea. also spent hours searching google and on these forums.. hope it helps somebody who's experiencing the same
