Base Attack (VCS83113)   and Ski Hunt (VCS83106) are just two of the 25 or so games by home vision. Most of these games aren'toriginal, but copies (Base Attack is the same as Bomb's Z-Tack). These clonedgames are mostly the same games that are offered by many of the more "underground" publishers like ITT, Bomb Onbase, Sancho (and , and the BIT Corporation(and Puzzy). Whether this "game-swappping" was part of a big deal or plainillegal, remains vague. The carts and artwork however, are very original, and it may bepossible that home vision had some game programmers as well.
