Gamepad Gameplay for the Atari 7800!

The Seagull 78 v2.0 is a controller adapter that allows the use of any Sega Genesis gamepad or other Genesis controller with your Atari 7800, providing authentic two-button gameplay control on all Atari 7800 games.

Simply plug your Sega Genesis or compatible controller into the Seagull 78, then plug the included 6' (1.8m) factory molded game cord into your Atari 7800 console. Buttons "B" and "C" on your Sega controller provide authentic two-button gameplay control on all Atari 7800 games. No other buttons are utilized on the controller while using the Seagull 78 adapter.

As a bonus, the 6' factory molded game cord may be used independently with any other retro game system that utilizes the DB9 connector, including many Flashback systems, Atari 2600, ColecoVision, Sega Master System, Sega Genesis, and many 8-bit computers.

Happy to report, this works on the 2600 Plus. Just played Choplifter with no issue other than my playing skills.

I own one of the first productions. Works very well.

These are fantastic, highly recommended. Longer review not required!

Works great, takes a bit of getting used to going from a joystick to genesis style controller for games but once you get used to it it works fine. Love that I can connect it to my Hyperkin controller which is super long

While a little messy-looking compared to plugging a controller directly into the 7800 (and basically redundant for me, once I bought a SuperTwin 78), it's well worth it if you want to use a reasonable gamepad on your 7800 here in the US, instead of wrenching your wrists trying to use the stock Proline controllers. (The nickname "Painline" is well deserved!)

I bought this well before they were available in the Atariage store. I'm happy for the collaboration.

Now, with that out of the way, this is an amazing product. Plans for such a device have been floating around since the days of CompuServe and GEnie, but if you want one that is not only professional looking, but of a professional quality, this is the device for you.

Edladdin does make some very nice premium controller solutions for the 7800, but if you're budget conscious, this and a working Genesis joystick works in a pinch for a low cost solution.

If you have the money, get one of Edladdin's premium joysticks. If not, this is a fine alternative.

This is a must buy for the 7800 unless you love hand cramps. In that case you should just keep using the Pro Line controllers. I will eventually get a second 78 adapter. My 7800 games have never played so well.

The adapter was shipped promptly. I paired it up with a hyperkin gn6 genesis controller I bought off of amazon. The result is amazing. I doubt that I will use the original controllers again

Being in the UK I had the pleasure of getting a 'europad' with my 7800, but you have to be kidding yourself to think it's a patch on the multitude of fantastic controllers the Seagull 78 opens up to you.
Probably my most played 7800 game is Xevious, I've become noticeably better and it's immeasurably more enjoyable now that I can use a Sega Mega Drive / Genesis controller with buttons that aren't made from a dish sponge.

I was curious as to whether the Sega infrared controllers would work and they do, but use an extension cable between the two as the Seagull 78 is just a fraction too long to allow the second controller plug on the adaptor to sit next to it.

'Must have' is something that gets thrown around a lot, but there is zero reason for anybody to handicap themselves with Atari's controllers when this is an option.


Do yourself a favour. plug in a Sega

An excellent adapter that works like a charm with every Genesis controller I have thrown at it.

IMO this is the best (besides being the cheapest) option for 7800 fans looking to avoid the awful stock Pro-Line controllers and retain two-button functionality.

These open up the 7800 to the wide variety of Sega Genesis controllers, which include arcade sticks, and pads with turbo functionality, many of which are fairly inexpensive nowadays.

I've used several controllers with this adapter, including the Sega Arcade Power Stick, Asciiware Power Clutch SG, stock Sega 3 and 6 button pads, Performance Gamepad 3 (my personal favorite due to it's discreet turbo buttons), Owl Pad, and the Beeshu Striker. All worked as they should.

It's a great addition to any 7800 fan's toolbox. Playing the games with well made controllers make a marked difference in how much you can actually enjoy them!

Rather than trying to locate one of the hard to find Atari 7800 pad controllers I purchased one of these and attached my favorite Sega Genesis controller. I recommend this for anyone looking to improve the Atari 7800/2600 experience!

Works great!

Own two of these, they are fantastic. Here's why.

Works perfectly with 3 or 6-button Genesis controllers. There is excellent response and no lag present. The Seagull 78 can even be used in conjunction with an AtariVox connected through it without issue. Ditto having an MCPDev cartridge attached.

It is well worth the money. The end results are Button B mapping to the Left Button/Button 1 of the 7800, and Button C mapping to Right Button/Button 2.
