∵Hi Asmodean. Firstly I want to say thank you for your hard work. Your tools is very use full.
But I had some problem extracting PSB file from まいてつ using expimg.exe.
expimg.exe always crash and stopped working. I've tried in Win 10, Win XP, Win 7 ... the result is same. I wonder what's wrong with that? Thank you.
Here is the error screenshots : http://s32.postimg.org/ntuvqgwet/errorpsb.png
(Ps. I've renamed the non unicode filename into test2.pimg)
