RPG software featuring fantastical landscapes. - Title: Super Black Onyx - Platform: Family Computer - Genre: RPG - Illustration: Fantastical landscapes I have many other retro games for sale, so please take a look! I am listing items at the lowest price at the time, so I cannot offer discounts. However, I can offer a discount on shipping for combined purchases. I have tested all cartridge software on a Retro Freak to confirm that it boots. While it generally runs more easily on the original hardware, some software may be difficult to boot. I do not guarantee the lifespan of the backup battery.
