Street Fighter II': Rainbow Edition - HADOKEN

At its height, Street Fighter II was so popular that demand was outstripping Capcom's ability to manufacture cabinets. Unscrupulous types looking to score a cheap board quickly turned to the grey market for one of many Taiwanese hacks.

Street Fighter II: Rainbow Edition was the most common, a super sped up of version of Street Fighter II': Champion Edition full of gameplay tweaks that put balance in the ground. I remember getting a go of it in our local video shop, the appropriately titled Pirate Video. Ryu's deadly unfair criss-crossing fireballs was one thing, but being able to switch characters on the fly by smashing the player start buttons was absolutely mind-blowing.
