I may be wrong here but doesn't the XMB use these files? So surely overwriting them while theyre in use in the XMB it is normal for them to become corrupted?
Also, I have a bug, the Hide Corrupt Files option doesn't hide corrupt files, they still there, and second Hard Reset on Homebrew doesn't work, my PSP still hard resets even with it disabled. Could this be something the Homebrew developer implemented in his EBOOT?
Thanks, and keep up the good work guys, just hope there is something that can be done about the people erroniously bricked by your retaliation device.
