the save game works only with the same game that you has played(sorry for my bead english bud i'm dutch)

if you got all first 4 gym leaders, and you've already went to the poekmon contest hall, go back to hearthome city, and challange the gym there, now you can.
you'll need to answer questions and go to the selected door, if you answer wrong, (I think, it didn't happen to me :P) you'll face a trainer.
Good luck.

lol.. I find it much easier to look at a walkthrough rather than ask on a forum. That's just me though. *shrug*

For the 100% saves go on gbatemp.net
It should have them on there... hope this helps
Oh... just copy and paste same name but change nds to sav
P.S you may have to convert sav to the right type depending on card (e.g m3 to r4, or something like that i think...)
