The Black Onyx — About this game
Create a party of up to five adventurers and explore the underground maze in search of the Black Onyx. The SG-1000 game tracks equipment and money separately for each character, so preparation includes checking the whole party. Return to the starting level for shops, healing and the bank. Fallen companions cannot be revived. The quit command provides character passwords, so keep the password for every adventurer you intend to use again.
