Currently, I'm working on eboot dissassembling with IDA and xorloser's plugins.
Also, I made a program which automaticaly translates (Microsoft Translator API) blocks of japanese text to english and corrects byte-size (if output english file is bigger, it truncates it, if smaller - adds spaces). Maximum chunk size - 70 KB at once. Speed is also decent. If it'll help Alexmagno, I'll release it.
