what I have now is a program running in the background waiting for a NFC tag. When it detects one it reads it and runs a program I wrote that closes an instances of Mame, AM, any win Games I have installed, etc. It then launches AM with a specific config, which loads certain displays. This works fine except I have to have different directories setup and stuff. I thought it would be easier if I could tell AM to load a specific display, but I guess this works. I will upload a video of this very soon as this is awesome stuff.
