I have two USA Turbo Duo controllers, one original PCE controller (no Turbos),
Ahhh, another example of the good ol' TG16 kickin PCE ass.
Seriously though, for all of the name-knocking and bad-cover-art rants the Turbo gets it is cool that it kind of "lived up to it's name"
...or at least the word "Turbo."
I remember when the TG was released Turbo buttons/switches were still a novelty or a feature that only high-end controllers like the NES Advantage and Max pads offered.
When I was ten years old a friend and I were looking at an issue of EGM and I was pointing to the TurboGrafx and excitedly telling him how "all of the controllers have turbo buttons!"
BTW, the NES Max controller is my all-time favorite pad. I beat Life Force, Metal Gear, TMNT 1, Ultima Avatar and most of my other NES games with that thing.
