Huh, what exactly is the "GBA Linkage" function used for?
I had the feeling that this is for games that transfer data from/to GBA/DS, such as the new Pokemon games and Harvest Moon.
Since normally you don't use up the GBA slot, they added stuff in those games that allow you to transfer data to and from the DS game to the GBA game.
I'm supposing that this will allow you to do it, considering most flashcards use the GBA slot.
Yes, this is exactly what it does. On top of that, it actually works too
. I got it to work with Advance Wars : DS and both Advance Wars 1 and 2. This is what I did:-
The Advance Wars 1 and 2 GBA roms were already on the cart. I used the new manager to load Advance Wars DS with the following settings : 4xDMA, Trim Rom, Soft Reset and the "NDS/GBA Linkage" box checked. A box appeared on the Linkage tab saying "Is a known DS linkage game".
After writing to the card, I put the miniSD card back into the M3 and powered on. Went into "Games" in DS mode. Highlight the GBA rom that you want linkage functionality for, and press X and then A. If done correctly, the screen should flicker. After that, select the DS rom and hit A twice to load the game. It should give you the message that it is loading the save data for the GBA rom, and then the DS rom. Saving worked perfectly like this as well.
This is a pretty cool function, even if it isn't super useful. I havn't tried it with Band Brothers yet, but I assume that it should work. It doesn't seem to be working for Kirby. For a full list of games that use this feature, just in case anybody wants to try it, see

Also, before anybody says it, this will not make Opera work. The required GBA cart for Opera has extra RAM built into it, so its a hardware problem. There is a slight chance that the M3 team might correct this in the future by rerouting Opera's request at the M3's built in RAM, but I don't think is is high on their priority list so don't expect it.
