The Seibu SPI System is Seibu Kaihatsu's custom arcade system board. The Seibu SPI system board uses interchangeable game cartridges, however, each cartridge is region specific, and must be paired with a board of the same region. Seibu SPI boards "update" when a game cartridge is changed. This process takes about 10 minutes to complete, and only has to be performed once after a cart change.
