When a console containing the FinalGROM 99, is turned on... The FinalGROM 99, starts-up from a GROM, header... "Press 2 for FinalGROM 99".
From what I understand, the FinalGROM 99, populates its own menu, using a routine similar to the one used in pre-v2.2, consoles.
I suppose that results in an empty TI, main menu, after QUITing.
