ROM Hack Small Question

[Inunah]

Is there a hack to add the expansion pack songs to the game Daigasso! Band Brothers? I don't need anything extra like translation, just the expansion added...

If not, then how would I add the .gba file for the expansion pack into the Daigasso! game?

(Yeah, if you've noticed I've posted more than one daigasso related topic today, but oh well, it's because i'm obsessed with it today.)

Is the expansion an actual GBA cart?
Or is it unlocked by putting in the GBA game?


If it's the first, then you should be able to load it into a Slot 2 device, like EZFlash 3-in-1.
If it's the latter, probably an AR code could do it.

Well it's its own separate GBA cart, I know that. Wikipedia says it too. *Highlights important info in the following Wikipedia quote*

As quoted from Wikipedia:
On September 26, 2005, Nintendo of Japan released an expansion pack called Daigasso! Band Brothers Tsuika Kyoku Cartridge (or Great Concert! Band Brothers Request Selection Cartridge in English). The expansion comes in the form of a GBA cartridge, which is inserted into the DS at the same time as the original Band Brothers card, making Band Brothers the first DS game that uses the GBA port for more than some minor unlockables. It features 31 new songs, which were chosen based on a survey posted on Nintendo's website in July 2005. The scores of the songs do not save after being played.


Also, I do not have a slot-2 device to use (I'm broke), so it needs to be something that stays in the slot-1 range.

I know there was one thread on GBATemp with a link to a place that had the expansion patched into the slot-1 game's ROM... But that link was dead and noone seemed to have it.
