Classic Game Room HD reviews the 3rd party aftermarket controller called the HIGH FREQUENCY for the Sega Genesis video game system. This is a six button controller for use with the Mega Drive (aka Megadrive) and fighting games like Street Fighter 2. It has turbo, rapid fire, auto and slow motion features just like the awesome NES Advantage does. Replace your existing controllers at your own risk though, although not a bad MD controller this one lacks the build quality of official Sega merchandise like the 6-button controller that we reviewed previously. The d-pad works ok, the X Y and Z buttons are there and fit and finish is now awful. If you happen to break all of your existing Sega controllers, joysticks or gamepads then check this one out. Play games like Sonic the Hedgehog, Revenge of Shinobi and Vectorman with ease and super HIGH FREQUENCIES.
