Fever Soccer (c) 2000 Seibu

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) 2000 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
U0563 LH28F800SU OBJ3-1
