The world's first 4-player adapter for the Atari 2600

The QuadTari is currently in-production, and will hopefully be on sale by the end of 2020. It allows for 4-player support for new games, or can be used (with supported games) to allow 2 joysticks to connect to the first port, freeing the 2nd port for an AtariVox or SaveKey.

The QuadTari is currently supported in ChampGames' Wizard of Wor.
