At last count, there are something like six Street Fighter games available for download from the Wii’s Virtual Console section. And for that truly old-school experience, you need a truly old-school controller. The $15 dreamGEAR Arcade Fighter Classic Gamepad for Nintendo Wii looks like it may be able to scratch that itch.
It looks similar to the standard Super Nintendo controller except you’ve got a couple extra main buttons, which makes it similar to the six-button Sega Genesis controller that was released after the original three-button version. Whatever the case, you’ve got six main action buttons and two shoulder buttons to play with. Happy punching.
