You are so hard coreInside UO needs the old files. Some people had a backup of it, but even then you can only browse files up to when the file type changed. I have used a program called 'uoreader'.

it's harder to find things in it because there are no thumbnails, but by using the 'get type id' action under 'others' in EC it's possible to find what you're looking for.
Someday I want to learn how to speak Brian.I've had better luck with UO Fiddler, though only up until ToL was released - muls after that broke Fiddler, and I don't think it's been fixed. As for the muls themselves, you can convert the current file type to mul; there's several tools to do that linked from runuo.
