The MBX Expansion System was released for the TI-99 computer in 1983, expanding its capabilities and opening up new possibilities for game developers. This expansion system allowed users to create their own games using a graphical editor, with support for graphics, sound, and even programming in BASIC.
Gameplay on the MBX Expansion System focused primarily on creating and editing game data, rather than playing games itself. Users could design levels, characters, and enemies using the built-in editor, which included tools for drawing sprites and creating tile maps. This made it an essential tool for developers looking to create their own titles for the TI-99.
