Wide range of controller support
Wiimotes, bluetooth HID controllers and MOGA controllers all work with this emulator, which is a great feature to have when so many games really require the precise input that a controller offers.
Game Genie, Game Shark and PAR cheat codes work with this emulator and it's library of supported games. Which can be good for users that want things like unlimited lives or infinite in game money.
The fast forward and slow down function allows users to easily speed up cutscenes and slow going portions of the game as well as slow down sections that users would like to view longer.
Viewing memory usage can be helpful in Pokemon games as the Pokemon with higher IVs use more memory. It is basically an easy way to get good Pokemon. Sadly this emulator does not support such a feature.
