NXPatcher - Create your own pre-patcher & list of Maple FTPs

Check if your version is v412 (in the pic I see 00412). If it is correct, then maybe your patch file is corrupt. Go and download it again.

How do I check that? I can't open the game since it's korean and they only accept korean ip's or coding or whatever.


EDIT: NVM I didn't see op had a tutorial, sorry about that.
