Super Street Fighter II - The New Challengers (Rainbow Edition)

One of a couple of blackmarket upgrades which appeared during Street Fighter II - The World Warrior's peak. The upgrade allowed players to throw multiple projectiles on the ground as well as into the air, and switch characters in mid-round by pressing your start button (the change follows the order Ryu-E. Honda-Blanka-Guile-Ken-Chun Li-Zangief-Dhalsim-Balrog-Vega-Sagat-M. Bison-T. Hawk-Fei Long-Dee Jay-Cammy), and teleport to another side of the screen. Results may vary as this was a blackmarket upgrade.

This was actually a blackmarket upgrade to Super Street Fighter II - The New Challengers. The upgrade was simply a set of ROMs, usually referred to as "Rainbow" or "Rainbow Edition" chips. This game is easily identified by the "Rainbow" pattern through the "SUPER STREET FIGHTER II" logo on the title screen.

I can only remember one other blackmarket upgrade by the name of "Blackbelt Edition". Capcom eventually took legal action against the manufacturers of the product. One version of this story is that Capcom brought Super Street Fighter II - The New Challengers out after the lawsuit to satisfy the general public. Another version is that Capcom brought Super Street Fighter II - The New Challengers into the market so that they would have a better reason for taking legal action as they would then be considered a threat to their market. Either way, part of the reason Super Street Fighter II - The New Challengers exists is because of the appearance of these blackmarket upgrades.
