GBA roms on NDS lite?!

sup people,I just got into downloading roms to play on my NDS lite after i received a n5 card.
so please bear with me, have no knowledge beyond downloading files on my n5 and playing.
i have been trying to download some gba roms but it seems they won't play...
can anyone explain how i can get these to work or if it is even possible?tried 0899 - Street Fighter Alpha 3 Upper (U).gbahelp please?

You need a Slot 2 flashcart.

hahahah thanks allot....
that was rather simple i'm slightly embarrassed.any software i need to download/install etc etc...i appreciate the help

Most slot 2 carts should support it natively, you cannot run them on a slot 1 cart no matter what.

Thanks allot for solving my rather diminute problem ;D
