Rapidfire

From publisher description:

Rapidfire is fast, easy to learn, cinematic, and adaptable to many different games. It works off a "single roll resolution". You roll 1d6, and then add your stat (rated -2 to +2) a skill (rated 1 to 6) and any other modifiers, and then compare it against a difficulty. In combat, that roll will tell you whether or not you hit, and how much damage you do (based on the damage rating of your weapon and how much you beat the difficulty by). Rapidfire was designed for [Edge].
