After trying others this was the only adapter that allowed me to use my ps2 pop'n music controller without the yellow button issue. Cant recommend enough if you wanna use non standard controllers.

I use this for my PS2 guitar hero controller and now I can actually use the whammy bar!

I bought this to use my NeGcon with an emulator, and it worked fine.
Since cheap adapters often don’t work with specialized controllers like the NeGcon, this product is the best choice.

If you want to connect your older psx controller to a pc without issues, look no further

I needed to pull some CAWs from a Wrestlemania 2000 cart I had and this came through for me! The native support in Mupen64Plus-FZ is what saved me, however, since the files I pulled from the utility didn't translate over as well. Great times!

Works as expected, perfect for dreamcast emulators but it also works on mister.

Bought this guitar not knowing what to expect. I am very new to these kinds of controllers but after some annoyances setting it up I realized that by default the various buttons use keyboard inputs so once I set my games to use them it worked like a charm. Very sturdy and responsive, and what surprised me is even moving the controller up to use Star Power worked. Have not tested it with a PS3, but as far as I can tell this is an excellent item and worth considering.

Responds well with no noticeable lag time using a real Nintendo Super Nintendo Controller on the Gamecube Gameboy Player. Gives a better feel playing the games than using the Gamecube controller.

Nothing to know--just connect everything and go!

Didn’t have to do any setup just plugged in and was able to play right away!
