Bank of China's "Great Adventure in Fitness Circle" game cassette can only be run on Bank of China's Nintendo Switch mainframe, but not on non-Bank's mainframe. This is the restriction that hosts in different regions have regional locking. Although the Japanese version of the switch machine is fully supported in hardware, it cannot play the fitness circle game of the National Bank version. Fitness circle is mainly composed of game cards and fitness circle hardware. The game card of China Bank can only be used on the switch of China Bank, and the switch of non-China Bank cannot run. Although the Japanese version of the switch machine has hardware support, the fitness ring of the Bank of China cannot be used in the Japanese version because it does not support game cards.
