The ppf patch isn't the problem,
the problem is the base of the iso, (is the most important thing)
all here.
I need to know if you have
the same disc data size: 3778070528 - 3.603MB
when you open your scrubbed zangeki no reginleiv iso with wiiscrubber,
match or not?
the size must match, then you can patch with ppf patcher.
[to make a scrub of the iso]
-Backup a untouched ZNreginleiv iso from the dvd.
-Open wiiscrubber and load the iso
-Then click the "scrub button on the left side"
-Now open the new iso
-You need to delete the partition 1, then see if the Disc Data Size match.
You can also use WBFS Manager 3.0 to scrub the untouched image.
If you still have problems
i will send you a package with the modified files to replace one by one with wiiscrubber
soon or later, the patch will works don't worry.
