bad rip of ISO one possibility
Bad patching another
bad copy to MS
Bad sector on MS
Just to name a few
Possible bad naming make the name shorter with out spaces
or FF_Type-0 could maybe fix it as well to long of name has caused that problem for me as well
I have backtracked enough to know everytime I rip and put it on my psp unmerged and unpatched the data is corrupted right off the base.
So what should I try?
