Someone asked me to compare the Revenge adapter to the Seagull 78.

So here it goes:

  • Revenge adapter cost is $18 Seagull 78 costs $24.99.
  • Revenge adapter has straight through design, Seagull 78 has right angle. I prefer straight through, as the console is usually in front of you vs. 90 degrees away.
  • Revenge adapter can be from 6 to 70 inches, same price. Default length is 6.5 inches. Seagull 78 cord is 28 inches. Since Sega Genesis controller has a long cord I prefer the 6.5 inch Revenge adapter in order to reduce cable clutter. I know some folks sit very far away from the console, and hence the 70 inch length works well for them.
  • Seagull 78 has a sticker on it. Revenge adapter has no sticker on it.
  • Revenge adapter's pcb shell is less bulky, 1.25 inches wide x .6 inches tall and 1.76 inches deep.

Tested with:
Sega brand 3 button Model 1650
Sega brand 6 button MK-1653
Sega brand 6 button with rapid fire MK-1470 (rapid fire works great too)
Sega brand 6 button wireless MK-1629.
Sega brand arcade stick

The adapter cable should work with 3rd party controllers, however I prefer to sell adapter cable for use only with Sega brand controllers as this is what has been tested.

Nice. So, these are custom made? Also, will these should work with the arcade stick, right?

Yes, custom made.


I made a small PCB that fits inside the connector on the left hand side (see pic above).


I tested it with the 3 and 6 button Sega brand controllers, so should work fine with Sega arcade stick as well.
