These engines are now commonly dubbed "fantasy consoles", based on a definition of the term on PICO-8's website, and roughly simulate the strict limitations of old game consoles and computers. Among these are TIC-80, which styles itself as a "fantasy computer," and Pixel Vision 8, which allows the user to specify the simulated hardware limitations they wish to develop under. The development of fantasy consoles, as well as development of games for them, has evolved into its own, almost exclusively hobbyist, sub-community of game development and programming.
