Something strange I found out and I have no idea why this works but it does.
Recently I decided I wanted a wireless solution for my dreamcast so bought a generic ps2/saturn to dreamcast adapter off ebay and also managed to find a sleak Sega Surf Wave wireless controller.
However the Sega Surf wave would not work for me straight off the bat. Infact originally I thought I had wasted my money. Because when connecting up the receiver to the adapter it will not light up or anything, just dead.
However I managed to find a work around by first using a Playstation one wired pad and loading up a game and then taking the playstation one pad out of the adapter and inserting the sega surf wave reciever.
The Receiver came to life straight away, lighting up and allowed me to use my Sega Surf Wave controller perfectly.
Not sure why it does this the surf wave is in perfect working order work flawlessly when installed on ps1/ps2 so thinking it must be something to do with the voltage in the adapter. Or maybe something to do with the metal plate thats on some control pad plugs.. Anyway its works and im happy, thought id share this because chances are it might work on other pads aswell. Just a shame I have to keep pluggin and unplugging the gamepads before use.
Ps the Sega Surf Wave is a dream to use so if you can find one dont hesitate, pick it up, defo recommended
