SNAC not working properly when using extension cord with PCE Controller

Unread post by vraskin »

I recently got PCE and Genesis SNAC adapters for my new MiSTer so I can use original controllers for Sega CD and TurboGrafx CD games. I have a USB3 extension cord that I was planning to use to go from the SNAC port on the IO board of the MiSTer to the SNAC adapter and controller since the original controller cords are so short.

The Genesis controller works great both with and without the extension cord. The PCE controller works perfectly when plugged in directly, but when I use the extension cord the left button only works when I hold down another button at the same time and the turbo switches don't work. I have 4 different PCE controllers and they all behave the exact same way. I even tried using a 3rd party aftermarket extension cord that I use with my actual PCE and got the same result. This is very unfortunate since the PCE cords are only like 2 feet long (why the hell were they designed this way???).

Is this a quirk of the TurboGrafx Core or am I missing something obvious?

Appreciate any help!
