Street Fighter II Engine (sometimes referred in to as Kart Fighter Engine) is an engine possibly made by Someri Team. They, along with Hummer Team and Shin-Shin use this engine a lot for their fighting games. Games using this engine had it somewhat modified every time.
Overview
Street Fighter II, where the engine possibly originated from.
Controls are the same throughout the games. B is to kick and A is to punch. It's similar to Street Fighter II, you become dizzy after a certain beating, there's 3 rounds and a timer starting at 99 seconds. (With the exception of Kart Fighter where the timer starts at 80.)
The punches and kicks hit on the 2nd frame of the animation while the close punches (when you're near the opponent), are only 1 frame and is slightly stronger. All specials seem to do the same damage unless they hit more then once (although this is an exception with some of the newer ones). Throws are usually forward throws but when the opponent is up against the wall, it varies what happens in the game. Most games where the 2P option is available, you have to press any button on 2P's control to get a 2nd player.
Games with this engine are usually seen as decent or somewhat good but are criticized for the opponent not bothering to block most of the attacks (usually jumping at the opponent and kicking them can result in an easy win), hitboxes being off and sometimes infinites that can be pulled off. (Some cases, the character is down and you can repeatedly throw them or projectile them)
Most of the games made on this engine are known to have an option menu with five difficulty levels.
SFII Engine V2
Many of the newer NES fighting games use this engine. The special commands are all the same. The commands are as follow:
- D, DF, F, a
- D, DF, F, b
- D, D, a
- a+b
The sprites are smaller compared to the other ones, reducing the amount of sprite flicker. Everything else seems to be the same.

Trivia
- In Starman vs. Kin Corn Karn's mediocre review of Kart Fighter, the trivia mentions that many of the bootleg fighting games for NES were based on the TMNT: Tournament Fighters engine also found on the NES, although this statement was given for absolutely no valid reason since TMNT:TF engine has more smooth physics than Street Fighter II Engine does.
