      Seibu SPI Hardware
      Seibu SYS386

      Driver by Ville Linde


      Games on this hardware:

          Raiden Fighters
          Raiden Fighters 2
          Raiden Fighters Jet
          Senkyu / Battle Balls
          E-Jan High School
          Viper Phase 1

      Hardware:

          Intel 386 DX 25MHz
          Z80 8MHz (sound)
          YMF271F Sound chip
          Seibu Custom GFX chip

      SYS386 seems like a lower-cost version of single-board SPI.
      It has a 40MHz AMD 386 and a considerably weaker sound system (dual MSM6295).

TODO:
- Alpha blending. Screen shot on www.system16.com show that during attract mode
  in Viper Phase 1 the "Viper" part of the logo (the red part) should be partially
  transparent. Same thing with the blu "Viper" logo when on the "push 1 or 2
  players button" screen. Note that the red logo is tiles, the blue logo is sprites.
  Same thing with the lights on the ground at the beginning of the game. They are
  opaque now, you should see the background tiles through.

Seibu Kaihatsu SPI Hardware Overview
1995-1998 Seibu Kaihatsu Inc.

This system (known as 'SPI') consists of a main board and a plug-in
cartridge containing the game software. The games on SPI hardware can
be swapped by changing the top cartridge and then moving a jumper
to the alternative position. This re-flashes some ROMs for a few minutes
(accompanied by a techno music track). Afterwards, a message tells you to
put the jumper back to the original position and reboot the PCB. The new
game then plays.

There were a few revisions of this hardware, though most are the same with only
minor changes such as different IC revisions etc.

Games on this system include.....
Raiden Fighters
Raiden Fighters 2
Raiden Fighters Jet
Senkyu / Battle Balls
E-Jan High School
Viper Phase 1
