Classic NES series

Has anyone an GBA-Emulator which is still running the Classic NES Series?At the moment i use the Visual Boy Advance Collectors Edition. And it always shows me the message: Game Pak error, turn the power off!Please help me, i would play this games!!!

why dont you try downloading a NES emulator instead

I tryed a NES-Emulator, but im sitting in front of my secont PC, wich is very low!(My good one is in repair)
All NES-Emulators have maximal a fps from only 5, so i try it on the GBA!But thanks for the fast answer!
