Alright so because I've seen quite a lot of people now not knowing how to properly set the triforce header or want to know if they have a valid file in their hands I decided to make a little
patcher tool which automatically sets a header readable by a human and also checks the iso SHA1 to make sure whatever they have there is actually a valid dump. Just drag and drop the file you have into the .exe and let it do its work.
As a small bonus I also let it remove some useless data in GP1 which exists because of a overdumped file and also let it fix a known bad texture in virtua striker 4 version 2006 (japan) if the dump happens to have that known dumping error. Let me know if it works like it should.
