Hi!

The RetroPie GPIO Adapter offers four additional pin break outs: 0, 14, 21, and 22 (see also https://www.petrockblock.com/forums/topic/using-other-gpio-pins-with-the-retropie-adapter/#post-2996). You could connect the Mausberry switch to these pins. You probably would have to configure the Mausberry script according to your pin choice.
