This Patch screws up the ISO

[Cyber Akuma]

I have two patches to install for the PSX game Bloody Bride

One patch translates the text into English

One patch adds English subtitles to the Movies

I have no problems with the text patch, but the movies patch dosent work, when I apply it the entire ISO just becomes a corrupt mess, sectors on it becoem unreadable, the TOC gets screwed up, etc

Anyone have any ideas why this is happenign and how I cna fix it?

I am using PPF Magic 3.0 and tried both isntalling the text then movies and installing movies first then text, both produce the same results
