I modified the pins for the RetroPie GPIO Adapter to match them with the gamecon driver (https://www.petrockblock.com/2012/08/26/gamecon-driver-module-for-nes-snes-and-n64-controllers-added-to-retropie-setup-script/). After that I also adapted SNESDev (https://github.com/petrockblog/SNESDev-RPi), which is a user-space driver for the RetroPie GPIO Adapter. So, if you want to be on the safe side, I would recommend to use the pin out of the RetroPie GPIO Adapter, which is described at https://www.petrockblock.com/2012/10/21/the-retropie-gpio-adapter/ and https://www.petrockblock.com/2013/07/09/getting-started-with-the-retropie-gpio-adapter/.
