                    driver by   Luca Elia (l.elia@tin.it)

Main CPU    :   Z80 (LH0080B @ 6MHz) + i8751 (Intel C8751H-88, protection)

Sound CPU   :   65C02 (R65C02P2 @ 2MHz)

Sound Chips :   YM2203C

Video Chips :   L7B0073 DATA EAST MXC 06 8746
                L7A0072 DATA EAST BAC 06 VAE8713

Board       :   DE-0298-1

Notes:

- The MCU handles coins and the bank switching of the roms for the main cpu.
  It additionally provides some z80 code that is copied to ram.

- One ROM (FI-1) is not used.
