DS lite can play GBA games it has a slot for them. The 3ds can't play GBA games from the cartridges. Nintendo did release 10 GBA games for ambassadors (people who bought early and paid full price for the hand held) through the Eshop but these games haven't been release to the public at large and there are no plans to add a GBA section to the 3ds Eshop.
