I just got a "Super Game Stick" on eBay...that came sans the red fire button caps.
It came from Venezuela so I'd just as soon not screw around trying to haggle with the seller (mi espanol no es bueno), and figure I can just replace them myself.
The button caps look like the same type used on the TG Products joysticks (of which the entire controller seems to be a clone). Anybody know of a suitable replacement?
As a side note, I have been able to find exactly zero information on the "Super Game Stick." No markings to be found anywhere (aside from the label on the face, which isn't especially helpful), and opening it up wasn't any more revealing. Who made it, where/when it was made and sold...no idea. All I can tell is that it's essentially a [very nice] copy of the TG joystick--the joystick is crisp and the buttons have a surprisingly beefy clicky action, which a lot of people would probably find obnoxious, but I dig it.
