Anyway to play GBA games on a NDS?

Like the title says. And I don't mean with a Slot 2 cartrige.

Currently you can emulate Sega Genesis, SNES, Game Boy, Game Boy Colour games on the DS via a slot 1 cartrige. Is there a GBA emulator that you can pop on your R4 and play GBA games?

No sarcasm please, if this is too n00b for you just ignore it. I'm only looking for real answers. Thanks.

Not possible, sorry. See http://dcemu.co.uk/vbulletin/showthread.php?t=74880 for a detailed explanation.

Best solution is to get a slot-2 device and use that to run GBA games on the hardware directly. I know you said you don't want to do this, but it's your only real option.
