So I want to strip the menus and everything down for a single rom use.. however after putting in the line for boot a single rom - I have this problem that when I power the system on clean (unplugged and then plug back in) -- it does like a double boot.. so it starts up, the piplay.mov runs, my hdmi goes out, comes back on and then the rom is to the title screen (missed the boot up screens)

Normally not bad - but TMNT has this whole cool boot up sequence that gets missed when this happens. How do I - a.) remove piplay.mov allowing me to see the entire bootup of the game?
