Gaechti's UO Patches

Working on EA/OSI and Freeshards!

How To

Here you will find information on how to apply the patches to your Ultima Online Client UOP Files (post 7.0.24)

Important notes

You cannot modify .uop files directly, theres is no tool known to me

What you need to do is convert the .uop files to .mul files, edit them and convert back

Getting Started & Backups!

1: Download LegacyMULConverter from cbnolok to convert UOP<->MUL:
DirectLink


2: Make a Backup of the following files

X:\Ultima Online Classic\artLegacyMUL.uop
X:\Ultima Online Classic\gumpartLegacyMUL.uop

I suggest you make a new folder called "Backup"
and make a copy of the files there


Preparation

3: Create a new folder somewhere, e.g.: X:\UOPMULConversion


4: Extract LegacyMULConverter into this folder directly (X:\UOPMULConversion)


5: Copy the following files

X:\Ultima Online Classic\artLegacyMUL.uop
X:\Ultima Online Classic\gumpartLegacyMUL.uop
to the newly created folder (X:\UOPMULConversion)


LegacyMULConverter - Convert .uop to .mul

5: Open up a CMD and navigate to that folder; Type e.g.: cd X:\UOPMULConversion


6: Type this to convert .uop to .mul:
LegacyMULCL-N.exe -x "X:\UOPMULConversion"


Apply the mods

7: Apply the mods on the .mul files in X:\UOPMULConversion as explained here:
http://www.burningsheep.ch/howto.html
Just ignore the backup part and use X:\UOPMULConversion as directory


LegacyMULConverter - Convert .mul back to .uop

8: Open up a CMD and navigate to that folder; Type e.g.: cd X:\UOPMULConversion


NOTE: delete any .uop files in X:\UOPMULConversion or repack fails because file exists!


9: Type this to convert the modded .mul to .uop:
LegacyMULCL-N.exe "X:\UOPMULConversion"

Now should have repacked UOP files from the patched MUL Files

Replace the UOP files in your UO Classic Client folder!


ARCHIVE

Below is the old how to as well as other possible tools. However I recommend you use LegacyMULConverter

ARCHIVE - Mulpatcher - Extract MUL file from UOP Files

Download UOFiddler from here:
http://uofiddler.polserver.com/
Open UOFiddler, make sure to load the plugin, go to the UOP Packer Tab
In the "One File" subtab:
(you need to convert both files, after another)

Output MUL: art.mul / gumpart.mul
Output IDX: artidx.mul / gumpidx.mul
Input type: ArtLegacyMUL / GumpartLegacyMUL
Input UOP: artLegacyMUL.uop / gumpartLegacyMUL.uop

ARCHIVE - Mulpatcher - Repack UOP Files from patched MUL Files

Open UOFiddler, make sure to load the plugin, go to the UOP Packer Tab
In the "One File" subtab:
(you need to convert both files, after another)

Input MUL: art.mul / gumpart.mul
Input IDX: artidx.mul / gumpidx.mul
Input type: ArtLegacyMUL / GumpartLegacyMUL
Output UOP: artLegacyMUL.uop / gumpartLegacyMUL.uop

NOTES / KNOWN ISSUES

Note: You need to unpack your .uop files into .mul files, apply the mods with mulpatcher, and then repack the modded .mul files into .uop files, copy and replace them in your UO folder

Note: If there is no UOP tab in UOFiddler, make sure its checked under Plugins AND restart UOFiddler
