Of course, morphgear isn't free. The ones that have been mentioned thus-far are. Personally, I haven't been impressed with morphgear for gba. I haven't really played with it for much else.
I will say that pocketgba has seen me through the entire game of final fantasy tactics advance. There were a few hiccups that required me to convert the save-game to visualboy advance (I think), play a scene in vba, save, convert to pocketgba, and continue on. It is simply an instance of the game having something that the emulator didn't support.
