7800 Mega Controller Adapter



7800 Mega Controller Adapter by RetroHQ

The RetroHQ Mega 7800 is a controller adapter which allows you to use your Master System and Mega Drive controllers with your 7800 or 2600. This includes Master System control pads, joysticks and also the light phaser as well as 3 and 6 button Mega Drive pads and sticks.

In normal operation the Mega 7800 lets you play 2 button 7800 and 2600 games with a more comfortable pad. In extended mode (where software has been written to take advantage of the Mega 7800) the 7800 is able to read all of the buttons available on the controller for additional gameplay control!*

The 7800 GameDrive in combination with the Mega 7800 uses the Mega Drive control pads to allow single button breaking into games (START), saving (Z) and loading (Y) of your games. This allows for the full retro gaming experience with the added comforts of an emulator! Truly the best of both worlds.

* Extended operation is currently only supported on the 7800, but should be possible to access from 2600 homebrew also.

Great! Using this along with a 'Hyperkin "GN6" Premium Controller for Genesis' I got via Amazon, it works good on my Atari 2600 console to play 7800 games (in which some games requires two buttons on a controller to play) and 2600 games.

I bought this to see if I could play the 2 button Atari 7800 games on my Atari 2600 Plus. I just qualified for my first race on Pole Position II. I am going to say it works. I also got through level A of Dark Chambers and then thought I better give this a review and let everyone know it works on the 2600 plus. Good Job Team.
