DS Games - unlockable content when a certain GBA game is inserted

[Funktion]

I think it would be useful if we could make a list of all DS games that have extra content unlocked when a certain game is inserted in the GBA slot.
If anyone has editions from different countries that still work in unlocking stuff it would be great if you could post, since most don't seem to work and this would help people that usually import games.

Wario Ware Touched + Wario Ware Twisted unlocks a special video of Mona doing something or other.

Feel The Magic/Project Rub - certain SEGA gba games unlock new costumes....i.e. Sonic Advance unlocks the sonic hat.

Pokemon Dash - pokemon gba games unlock sillouettes of your part pokemon to race around.

I posted about this back on the old CE forum, with regard to Advance Wars: Dual Strike:

OK, I've just stuck AW2 (US version) into my DS along with AW:DS, it doesn't reduce the cost of items to buy, but it does allow you to buy extra items. I don't know if simply having the cartridge installed does the trick, or how much progress you've made affects it (I didn't play AW2 much, wasn't in the mood for it at the time); anyway, here's the extra items you can buy:

Sturm's Land (Map) Cost: 1
Lash's Land (Map) Cost: 1
Advance Warpaper 2 (Wallpaper) Cost: 1

Trying it with AW1 (US version) in my DS, different items are now available:

Hachi's Land (Map) Cost: 1
Nell's Land (Map) Cost: 1
Advance Warpaper (Wallpaper) Cost: 1

It seems completion does not affect what's available, I was asked if I'd finished the game when buying an item with AW2 installed.
