Stone Raider II is a clone of the cross-platform (Atari, Apple, Commodore) smash, Boulder-Dash... which itself borrows elements from the arcade game Mr. Do. You have to gather the diamonds underground, while making sure that you don't cause diamonds or boulders to fall and crush you. Unlike Mr. Do, the actual playfield is larger than a single screen, and it scrolls in all 4 directions. There are also creatures wandering around as well, and nice little musical interludes when starting and ending a game.
This title was originally released in Europe for both the Dragon-32/Dragon-64 computers (clones of the Coco 1 with some improved hardware, like the keyboard) and the Coco. There, because of the PAL TV system used, the game was black and white, in full 256x192 graphics. The slightly modified for North America Coco version features artifacted color, but is otherwise identical. There are 25 levels in all, and it features a little bit of history of the game, and instructions, scrolling at the bottom of the title screen. The two player characters' graphics are based on Mario, of Donkey Kong fame.
Unlike the Diecom Prodcuts clone, Bouncing Boulders, this version only required 32K to run.
