fixed. You can then make separate changes to each individual emulator by editing the configuration files for that emulator.

For NES the file is located here
/home/pi/RetroPie/configs/nes/retroarch.cfg
For MasterSystem
/home/pi/RetroPie/configs/mastersystem/retroarch.cfg
For MegaDrive
/home/pi/RetroPie/configs/megadrive/retroarch.cfg
In each file you will need to type out only the buttons you want to change and voila!!
