If you need to be able to use a mouse for a particular game, do the following:
Launch a game then go to the Amiberry Menu by pressing Select + X
On the left side of the screen, scroll down to Input.
Hit right and set Port 0 to Go-Super Gamepad and change Default to Mouse
Set Port 1 to Mouse and leave Default as default
Then hit left and scroll up to configuration.
Hit right and scroll down to the Save button and hit the A button. This will save this configuration as the default configuration for that particular game when it's loaded.
