The detailed differences between this hack and the original Streets of Rage 2 (USA) are listed below:

* The 4 playable characters have been replaced with Hiei from Yu Yu Hakusho, Erza from Fairy Tail, Sailor Mars from Sailor Moon and Android 18 from DBZ.
* Completely new moves and physics for each character. They each play very differently.
* 4 new bosses.
* Air Combos have been added, find unique ways to style on your enemies and do massive damage.
* Holding the jump button while getting knocked down lets you land safely from all hits, similar to throws.
* 6 Button Support. Back attacks are used by simply pressing the Y button. They have been buffed significantly.
* KO Count can be viewed by pausing the game.
* 8 completely new songs have been added throughout the stages.
* NO CONTINUES. The stakes are higher. Choose your character wisely and make it to the end!
* Mania difficulty (S Rank) and Level Select are available at the start.
* Jump lag glitch has been fixed.
* Slightly raised HP for some enemies because of the powerful air combo system.
* Enemies are more aggressive overall.
* New color palette for some enemies, to clearly indicate they are much more aggressive.
* Remixed item placements. Hidden 1-UPs have also been replaced with Gold which is now worth 50,000 points.
* Player characters now have an animation while in the air as they are recovering from being thrown.
* Player characters can now move during the slow-motion after defeating a boss. Go for a photo finish!

***Known issue*** When playing 2 player mode there are a ton of graphical issues when big sprites are present.
