I am looking for an adapter that will allow me to use an original NES Advantage joystick with a Gamecube and/or Wii.

Most of the ones that connect to a Wii mote have significant lag and do not seem to support the NES Advantage.

Has anyone used the Raphnet NES to Gamecube adapter? I'm guessing that an adapter going directly into the Gamecube port would be less likely to have lag and would probably support the NES Advantage as it would have more volts available perhaps.

My end goal is to use this with Wii homebrew games. I bought one Wii mote NES/SNES adapter but the lag is terrible with Wii homebrew. It does work on a SNES Classic nice though with no lag, but not with a NES Advantage. I wonder if I could add volts somehow with an external power source...

Other: I think the NES Advantage is one of the best controls ever. They can be bought very cheap, and if you have a NES to USB adapter they are ideal for playing MAME. With the select and start buttons you have a four button controller. I think people highly overlook the NES Advantage as a quality, cheap and functional joystick for MAME purposes.

Thanks for the input.
