Build the Ultimate Intellivision console! The Ultimate Intellivision Console is a small portable unit that easily hooks up to your TV and allows you to play all your Intellivision games. What makes this the Ultimate console? All other systems, such as the Intellivision Handhelds and Flashback units, had limitations such as poor emulation, poor sound reproduction, and/or poor video output. The Ultimate console allows you to connect to your TV using an HDMI connection, install all your game images, and use the original controllers including the ECS keyboard, Synthesizer, or any other USB controller.
