Hi all I just received today a Japanese Baku Baku Animal cartridge and I have a US STV pcb. When I turn it on with the cart it says that operation of this cartridges is disallowed in this country. Error on cartridge. Press "Service" to continue. When I press the "service" button it shows a ST-V screen that repeates itself and it says "Check cartridge for improper installation" Is there a problem with the cart or do I have to do something to the mother board in order to play imports? Please LMK

THANX
