This is not only one of the oldest plug-and-play systems, but also the first plug-n-play to be licensed.

The Atari Joystick Controller TV Video Game System was made in 2003 in Jakks Pacific's Plug It In & Play TV Games plug-n-play game system lineup. The device itself is designed to look like the joystick used on the Atari 2600.
Pac-Man 256 is an official hack of the original Pac-Man starting right before Level 256; not to be confused with the 2015 game.
It was only released in Pac-Man Connect and Play.
Features Pac-Man, Pac-Mania, New Rally-X, Galaga, Galaga '88, Dig Dug, Super Xevious, Rolling Thunder, Dragon Spirit, and Mappy. Additional ROMs for various formats (NES, Game Boy Advance, Atari 2600/7800, etc.) can be added via a Micro SD card.
Features NES/Famicom versions of Pac-Man, Dig Dug, Galaga, Galaxian, Mappy, Sky Kid, and Xevious. Pac-Mania is included in Wal-Mart while The Tower of Druaga is included in other stores.
Slightly modified NES/Famicom versions of Pac-Mania, Dig Dug II, and The Tower of Druaga. Seemingly only released in Canada. A second volume was never released (or announced).
Features Pac-Man, Super Pac-Man, Pac & Pal, Pac-Man Plus, Galaga, Galaxian, Dig Dug, Mappy, Bosconian, Xevious, New Rally-X, and Pac-Man 256. Shaped like an 8-bit graphic of Pac-Man (or as a Blinky in the PAL version).
Features Ms. Pac-Man, Galaga, Xevious, Mappy, and Pole Position. A later revision adds the ability to save high scores, which all future Jakks Pacific systems also featured. It was re-released in 2005 with a GameKey slot, which were compatible with "NM" GameKeys.
