In 2010 "Virtual Play Games" published Intellivision Lives! for the Nintendo DS handheld system, also developed by Realtime Associates. It features wireless, multiplayer support using a single game card. The "Nintendo DS"'s touch screen emulates the Intellivision's 12-button keypad including an overlay image for each game. The Nintendo DS lacks a 16 direction pad used by some Intellivision games. This limitation was overcome, in "Vectron" for example, by mapping directional inputs to the touch screen. Only 10,000 copies of the Nintendo DS edition were ever released.
