New core option at the top of settings. Choose between xemu or hakuX. Much faster performance with hakuX. Might have worse compatibility or other problems. Please report problems to my GitHub, so I can fix them. Thanks to rfandango for making hakuX!
I added a save game manager. Press the save icon at the top of the main library screen to open it. In game saves are shared between the 2 cores, but snapshots are not shared. They are separate due to how they are made.
