/* 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

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)
