Mega 7800 - Controller Adapter for Atari 7800

The RetroHQ Mega 7800 is a controller adapter which allows you to use your Master System and Genesis/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! Truely the best of both worlds.

Hazel I. ★★★★★

Finally, I can use my old Genesis pad on the 7800 without any lag or weird button mapping issues. Plugged it in, fired up some Joust, and it just worked perfectly with both my 7800 and 2600 games. The solid build and tight fit make it feel like it was made for the system.

Robert ★★★★★

I was dreading fiddly adapters, but this one just works—plugged in my old Genesis pad and it recognized it instantly on both my 7800 and 2600. Being able to use those controllers on both consoles is a huge plus.

Eli ★★★★★

Digging out my old Genesis pads was worth it just for this. Plugging it into the 7800 and having the D-pad actually work on 2600 games is a game changer, and setup took me less than a minute. The adapter feels solid, and now I'm finally playing through my backlog without wrecking my thumb on those s
