can NDS play GBA files?

I am using NDS with a DSTT and a Kingston ultra sd. I have wrar. but certain games that I have as a GBA file will not play on the NDS. Is it possible to pay GBA files on NDS? Thanks

I don't think you can play GBA roms with the DSTT.A slot 2 cart is required to play GBA roms.

fair enough, thanks
