  It's a standard 486 PC motherboard, gfx card etc. with expansion ROM board

  probably impossible to emulate right now due to the bad / missing (blank when read) rom
  although it would be a good idea if somebody checked for sure

TODO:
- Doesn't detect proper CPU type;
- "Memory test fail" at POST, needs um8498f "memory controller" emulation
  (non-PCI with shadow RAM?), also cfr. correlated at.cpp romsets;
- Sometimes POST will trip an invalid groupFF_16 modrm FF at 000F00B2, causing an hang;
- bp 932d1, ROM banking that reads at 0xffffe? Is um8498f ROM boot capable?

Notes:----------

Main PCB (it's a standard 486 motherboard):
1x Keyboard DIN connector (not used)

Video PCB (it's a standard VGA ISA board):
1x VGA connetctor (to ROMs PCB)
1x red/black cable (to ROMs PCB)

Sound PCB (missing, it's a standard ISA 16bit sound card):
1x stereo audio out (to ROMs PCB)

ROMs PCB (it's a custom PCB, with ISA connector to motherboard on one side and JAMMA connetcor on the other side):
1x ISA connector (into motherboard)
1x JAMMA edge connector
1x VGA in connector (from Video PCB)
1x stereo audio jack (from sound card)
1x 13x2 legs connector(only 2 legs used for red/black cable from Video PCB)
1x trimmer (volume)
2x 8 switches dip

Info:----------

------------------------------------------
I have:
3 Main PCBs (all of them without 80486)
11 Video PCBs
4 ROMs PCBs (only one has EPROMs)

Game was programmed by Giovanni Tummarello and Roberto Molinelli in 1990 for Amiga;
it was an action/strategy videogame published by Proxxima Software (Rome, Italy) and
later ported to PC machines and published in 1994 by AIM Games software (US) and in
Arcade Version (Coin-Op) by InfoCube (Pisa, Italy)
