SNES Performance Tweaks

The best solution I know is to use rfkill.

The basic idea is to install it with
sudo apt-get install rfkill

And use these commands to "kill" or unkill WiFi.  You can also kill Bluetooth, I think, and you could add a menu item to do these if you wanted.
sudo rfkill block wifi
sudo rfkill unblock wifi

There's a bit more info at http://www.sudomod.com/forum/viewtopic.php?t=3239

I haven't heard from anyone that has set these up as a menu item yet, but I'd be very interested to know how that works out.

I have...  I did this on my GB build.  You need to copy 2 .sh files to the retropiemenu folder in your homedir (you have to scp it there as it doesn't show up on the SMB shares).  Mark them as executable (sudo chmod +x *.sh)  I then added it to my gamelist.xml file in that folder so it showed up nicely...  Here are my files (renamed all to .txt so I could upload, enable and disable are .sh and gamelist is .xml).  (Oh and this also requires rfkill be installed)

Thanks so much, both of you!

I also edited the files (thanks for providing them), added a logo and now they show nicely in the retropie menu
