Any gba emus with decent framerates?

I tried megaman zero 2 on VBAPSP which was a bad move. it took almost a half hour to get past the intro. Are there any other emus that i can put onto my psp?

there are absolutely no GBA emus besides VBA, that are compatible for the psp as of right now. sorry. Only VBA works right now, and it works very very slowly.

hmmm... damnit, now i cant try the new rebelstar game...

... yes u can if u download a game off the internet then u are agreeing that u own the original copy...so if there is no way u can try it then ur illegaly downloading games
