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.<ref>[http://en.wikipedia.org/wiki/Seibu_SPI_System Seibu SPI System - Wikipedia, the free encyclopedia]</ref>

== Hardware Revisions ==
There are 3 known revisions of the Seibu SPI system. Revision 1 is the original release board and can be identified by "(C)1995 SXX2C-MAIN V2.0" printed on the main board. Revision 2 has a cleaner layout but no notable changes. It can be identified by "(C)1998 SXX2C-MAIN V2.1" printed on the main board.

Finally a Single-board revision, Seibu SYS386, was produced for the re-release of Raiden Fighters 2 - 2000 & Raiden Fighters Jet 2000. Both have a 40MHz AMD 386 and a considerably weaker sound system (dual MSM6295), resulting in audio issues. A RFJ2000 Single PCB variant exists that uses the proper Yamaha sound system instead.

== Changing Cartridges ==
Switch the system off, swap the cartridge, move the position of jumper JP1, switch on, wait for timer and game boot, and then switch JP1 back.
