No-Intro Name: Streets of Rage 2 (USA) (No-Intro version 20130710-102701) ROM/File SHA-1: 8B656EEC9692D88BBBB84787142AA732B44CE0BE
Hack description
One Piece:
-Characters replaced by Luffy, Nami, Zoro and Sanji.
-All characters are fast and agile.
-The game has pretty smooth animations.
-The voices also match their characters.
-Weapons removed from some enemies.
-All bosses except JET have increased HP.
-Neutral Air Attack is now Air to Air. Works great for juggling an opponent in a corner or while playing in Co-op, but can miss when attacking a ground target.
-In two-player mode, if P1 chooses Zoro, the picture will be blinking during his combo finisher. To avoid problems, the second player should choose Zoro.
-Also in a two-player mode, small graphical artifacts are possible for some enemies at the first and last levels.
Thanks Dha Lau Hoo and MetalOverlord64 for the advice.
