I got the same error. I just did a simple repair on that .rar file using WinRar and it extracted fine. Game is working perfectly fine on a 4.21 Rebug CFW PS3. Tested the game with PS Move, played a couple of levels.
Works on my 3.55 like a charm!!! I have DUPLEX Repack version of the game and this new eboot patch. Just replaced param.sfo, eboot bin and model_shader_pack.sdat in usrdir folder shader. I start with story mode, the game is awesome! Thanks DUPLEX!!!
Guys, I must inform you that first Repack version of game don't work on story mode, just freeze on 3rd battle. I try several battle in versus mode against cpu and all works well, I think that's most important for fighting game! Who cares for story mode!
