  Fever Soccer (c) 2004 Seibu Kaihatsu
  
  A down-grade of the Seibu SPI Hardware with SH-2 as main cpu.
  
  driver by Angelo Salese & Nicola Salmoria
  
  TODO:
  - Add eeprom emulation;
  - Real Time Clock emulation (uses a JRC 6355E / NJU6355E)

  Fever Soccer (JAMMA based Gambling Game)
  
  Seibu Kaihatsu Inc.
  
  PCB (c) 2004 SYS_SH2B + SYS_SH2B Rom Board
  
  Very simple PCB contains:
  
       CPU: Hatachi SH-2 (HD6417604F28)
     Audio: OKI 6295 (rebaged as AD-65)
  GFX CHIP: RISE11 (custom graphics chip with programmable decryption)
    EEPROM: ST93C56A
       OSC: 28.63636MHz
       DSW: Single 4 switch
  
  Other: Battery (CR2032)
         Sigma XLINX 9572
         JRC 6355E Serial Real Time Clock (connected to a 32.768KHz OSC)
  
  RAM: BSI BS62LV1024SC-70 (x2)
       EtronTech EM51256C-15J (x4)
  
  
  PRG0.U0139 ST M27C1001 (PCB can handle up to 27C080)
  PRG1.U0140 ST M27C1001
  
  PCM.U0743 ST M27C4001
  
  On the SYS_SH2B ROM BOARD:
  OBJ1.U011 ST M27C160
  OBJ2.U012 ST M27C160
  OBJ3.U013 ST M27C160
  
  Not used / unpopulated:
  
  U0145 LH28F800SU (Alt program ROM near SH-2)
  
  U0744 LH28F800SU (Alt PCM ROM near AD-65)
  
  U0561 LH28F800SU OBJ1-1 (near ROM BOARD connector & RISE11 chip)
  U0562 LH28F800SU OBJ2-1
