Works well and is solidly built like all 8bitdo products. 8bitdo uses half the color scheme so you won't get a good match for your TurboGrafx machine. In practice, turbo buttons are not a good substitute for slide switches. The controller is also small, more like an NES pad than a TG-16. It will be good for some hands and bad for others. All in all not what it could be. Disappointing.
