backuping up roms

EDIT: I'm trying to backup my games to my comp via NDS_backup_wifi toolWhen I put in my DS game it says the card of slot-1 cannot be recognized, tried a few dif games.Using: DSi, acekard2i if that matters

To backup just put your micro=sd in via SD or USB and just copy all your roms and sav data onto your computer.

EDIT: fixed original problem but have another

You need a DS/DS Lite to do a backup as the NDS Backup tool doesn't support DSi Hardware... :\
