SNES9x - command to enable mouse

Hi

I am using Launchbox as my front end, and have SNES9x 1.60 as my SNES emulator.

I had to reinstall Windows recently, and forgot to backup my Launchbox settings.

I have forgotten the command on how to enable SNES Mouse emulation in Launchbox for SNES9x.

I have tried the following commands but they do not work.

-port1 mouse1
-port1 mouse2
-port2 mouse1
-port2 mouse2

Any help is greatly appreciated.

Mouse emulation works when I manually click INPUT > SNES MOUSE. But I want to avoid having to do that, and have the emulator automatically launch with input already set to the SNES Mouse.

I have no problems with SuperScope games using the -port2 superscope command.

Thank you.
