Thank you, it works now.
It's weird, the BPic folder was with the download, but for some reason it didn't show up in the installation path of the game (I extracted everything... I know because I even did it and even redownloaded it several times) I tried the game and now it finally works, now the game works both patched and unpatched.
Sorry for the trouble, it seems the problem was completely unrelated to the patch or the need to have the patch. (I was tired of trying chinese, japanese and english locales (Spanish computer))
The patch seems compatible with spanish language systems (Since I think I did read it may not be compatible with all), though I barely had time to start playing, so I may get crashes later, thank you again for the help
EDIT: Patched crashed somewhere mid-way stage 1 (with Marisa), I guess it couldn't last... non-patched with chinese locale lags less with inputs, but still crashes at the same point. I guess I'll give up or try to get help later at this game's thread.
