When the machine is turned on, it will be in NORMAL mode.  Then all of a sudden it will go into MENU mode.  I cannot clear unless I pull the battery to de-energize the boards.  Then, on that start up, it will show error code 91, error name SAVED GAMES CRC ERROR, error site, POWER ON.  I will go to the initialize and game will operate for a while in NORMAL :99- mode but then go back to MENU mode.  Can anybody help me???
