The Systema TV Boy II — NES Clone with Built-in Games
The Systema TV Boy II was an unlicensed NES-compatible clone console with built-in games — combining NES hardware compatibility with a library of pre-installed games, allowing play without cartridges while also accepting standard NES cartridges. These NES clone consoles with built-in game libraries were popular budget gaming devices throughout Europe in the early 1990s, often including dozens of simple games stored in ROM. Systema was a UK-distributed budget gaming brand, and the TV Boy II’s combination of built-in games and cartridge compatibility gave it flexibility that made it a popular choice for budget-conscious British families.
