List of Nintendo DS games with Game Boy Advance connectivity

Between the years 2004 and 2006, Sega published Nintendo DS games with features that can only be unlocked if a compartible Game Boy Advance game is inserted into the GBA slot of the system (making impossible to do that in the DSi, DSi XL, DSi LL or any 3DS system due of fact that they lack this slot).
