have 2 default.cfg
one that will be let you in the MENU, and one that you can't.
For the one that you don't want no one in menu, change the settings to NONE, I mean type the N O N E quickly.So you need to hit 4 buttons N O N E to access it and of course one or more keys are missing in your JOYSTCIK/BUTTONS so no one can access it. Then use the original .cfg that is iset to the TAB key to access the menu. Or you can just use one CFG and type in N O N E quickly to access the menu with your keyboard.
