full save someone? in 1 moment it crashes
Do you have a previous save to that scene where it crashes?, because I can try to extract the text strings, and see if I can find any translated string in that scene that generates the error. And a save that allows to load the scene with that error or a screenshot showing some previous text, would help to try to find if there is any translated string that causes it, if it doesn't happen with the japanese version. And the files with translated texts that overwrite the English patch are Arc01.dat and Arc04.dat.
Although you can also try to pass that scene with the original texts in Japanese, replacing the files Arc01.dat and Arc04.dat by the original files that brings the image arukazoku.iso, and after doing so exit the game and replace them again by the translated ones. Because a full save is not very useful, when this game stores a save (save00.dat, save01.dat... save0x.dat) for each scene where you have saved it in the root folder of the game.
