Emulators for Nds

Please,do you know any gba emulator or psp emulator for Nds?
Thanks
(sorry for my English but I am french) ;D

the DS is not capable of running psp games...and there is no GBA emulator, you'll need a GBA flash cart to play GBA roms-=EDIT=-if you have a DSi then I beleive there is no way for you to play GBA roms

Thank you

With a DSi you can play GBA games using the iPlayer (or something similar, I honestly don't remember the name entirely) flash cart.

Correct. Though buying another flash cart if you have another one already (only?) to play gba games on the Dsi does not seem worth it in my opinion. If you have a lot to spend, sure why not :-P
