  Thanks to Olivier Galibert for the handy bitswapper tool :-)
 
+- The first time you boot a game (without proper NVRAM) it tells you to RESET - Hit F3 - When
+  the game reboots, it flashes between "0" and "1" Hit the TAB key and flip Key1-0 to "ON" and
+  the game starts. Quit the game and use the created ".nv" file for the default NVRAM file.
