Developer: n.a.

This page collects games whose developer is unknown: “n.a.” stands for “not available”, and no programmer or studio is credited. For now it holds a single cartridge, Hole Hunter, a hammer-and-holes game made in Taiwan in the early 1980s. It is the same game as Topy, which Home Vision and Gem sold in Europe, and it also turned up as Mole Hunter. You whack rats as they climb out of their holes and keep clear of the snake, all against a 20-minute clock.
