Hi, I know you can change the battle music in Megaman Battle Networks 5:Battle Team DS by inserting a "MMBN" GBA game, for example if I want the Megaman Battle Networks 3 battle music I only insert the GBA game and play the 5 with the music from the 3. Now my question is, is there is a way of doing this without the GBA card?, more specific on a DSi. And if it's possible to have the bonuses every GBA game give, like the misions and the new NPCs. If can be of help, this is the thread where is all the info about the DS-GBA linkage: DS - GBA Linkage Guide, What games work with..what games? ] Thanks in advance.
