Trebor Posted February 28, 2015 Share Posted February 28, 2015 I believe it was Trebor who solved this for me as I had the same issue....it has something to do with the difficulty switches on front of the 7800--but for the life of me right now I can't say how to set them to get individual button play. Xevious Left Difficulty Switch: B/Left Position = Independent Fire [Left-Button 1] and Bombs [Right-Button 2]. A/Right Position = Both buttons do both weapons. 1 Quote Link to comment Share on other sites More sharing options...

Do alot of 7800 games behave differently based on the position of the difficulty switches? Quote Link to comment Share on other sites More sharing options...

ave1 Posted May 1, 2015 Share Posted May 1, 2015 Got mine and it works great. I tried out all of my Genesis controllers on my 7800 and there are no problems. I decided to experiment a little and plugged a Master System controller in, but the buttons would not function. I then hooked up my Colecovision and tried three options: 1) started a game with regular Coleco controller, removed it, and then plugged Genesis/SG78 combo directly to port 1. No go. 2) did the same thing with the Master System controller. No go. 3) tried a Champ Keypad (it allows for a passthrough Atari 2600 or 7800 controller) with both Genesis and Master System controllers hooked up to the Seagull 78 but got nothing with either. Oh well- I'm still very excited about all the possibilities I have for playing my 7800 games 1 Quote Link to comment Share on other sites More sharing options...
TheGameCollector Posted May 8, 2015 Share Posted May 8, 2015 Hey I'm a lot later to the party than I would have liked to have been. I just remembered this project and I am glad to hear it was completed and people are happy with it. I hope a few months down the road I can still get one of these. I'll be moved by then I hope and not be paying as much for rent. I have favorited Edladdin.com so I don't forget to buy one or two of these once I move. 1 Quote Link to comment Share on other sites More sharing options...
Jai Alai Posted June 10, 2015 Share Posted June 10, 2015 I tested mine today. This adapter is one of the best investment you could do to your 7800. It has been a perfect purchase for me. Works Great. Thank you. 2 Quote Link to comment Share on other sites More sharing options...
