There is no PVR for the menu, at least none which would be directly accessible. There is one for its backdrop though.
And concerning the 15 minutes thing: are you sure about the possible workaround? I remember that I have tested the DL emulator with "Dr. Robotnik's Mean Bean Machine" - an external ROM that is - and it didn't work. Got a screen that told me something in Japanese and then sent me back to the menu after that amount of gameplay.
