Just an index file to scan the directory it is in for various retro rom files and spit out a Tinfoil index json.
Change the HAUTH lines for yours, as well as the baseURL.
Drop all roms and this index.php file into a directory named Retro into your host's root directory.

Updated for recursive directory scanning.

Added all "supposed" Tinfoil supported extensions.
