I have tested the 7.1 version.

In generally It's have shown a great improvement. But the speed is still be main problem of this emulator.

In my opinion the next version should consider :
  - Speed
  - How about give full window screen feature.
  - Please give a shortcut to save and load slot because It's annoying if user must click the menu again and again.
  - Please consider about loading GBA save game because in some game. There are some feature to load an GBA        save game like in Harvest Moon DS.
