Street Fighter Zero 4

Street Fighter Zero 4, also known as Street Fighter Heavenly Kings 4 and Jieba Tianwang 4 is a bootleg port of Street Fighter Zero 3 released in 2000 for the Game Boy Color.

As a port, Street Fighter Zero 4 cuts out the majority of mechanics from Street Fighter Zero 3 such as the Super Combo gauges, the -ism styles and the Guard Power gauge, making it much more similar to Street Fighter II in its gameplay. A is used for punches while B is used for kicks. You can also throw the opponent while holding forwards or backwards and pressing A. Each character has about either two or three special moves, most of them being the same commands. Basic attacks appear to do chip damage to the opponent which is unusual for a Street Fighter game. There also seems to be a brief invincibility period after you finish getting up from a knockdown where you can't be hit. If you get hit in the air, you never recover mid-air and instead, lie down once you land.

Only thirteen characters out of the original twenty-eight are in this port and four of them are clones, making the roster only consist of nine unique characters.
