Requirements

• PS2 Tools (cdvdgen, iml2iso) Download
• PAK Tool Download

Step by Step

1. Extracting ISO

If you use Windows 10 or newer, you should be able to open ISO contents by just double clicking at the .ISO file. This will mount the ISO as a virtual drive.

Open up the newly mounted drive and simply move everything from the virtual drive to any folder (preferably create one just for UMKD stuff).

2. Replacing Files

Copy MKDA.PAK near PAKTool.exe, drag it onto the executable and wait until it is extracted.

Replace any files in the ps2dvd\art folder!

Once replaced, drag the ps2dvd folder back onto the executable, wait till it finishes then rename ps2dvd.PAK to MKDA.PAK.

3. Building a new ISO

Open “cdvdgen”, it’s a tool designed to create PS2 DVD and CD images from scratch, it CANNOT edit existing ones!

CDVDGEN Steps

1. Once launched, select Create new project
2. Select DVD-ROM Master Disc
3. Go to Volume tab
4. Once in volume tab, fill the respective places with following data, change SLUS (SLES) serial to match the game
   • Master Disc/Disc name: SLUS XXXXX
   • Master Disc/Producer Name and copyright holder: MIDWAY
   • Master Disc/License Area: America or Europe
   • Volume Identifier/Volume: SLUS-XXXXX
5. Go to Directory tab
6. Start dragging files from your previously extracted folder onto this window. Make sure they end up in following order/hierarchy:
   • SYSTEM.CNF
   • NETR.OVL
   • NTGUI.ELF
   • SLUS_XXX.XX
   • AREA51 (MKD, folder, can also be removed)
   • CNF (folder)
   • LICENSE (folder)
   • MODULES (folder)
   • MOVIEPS2 (folder)
   • NETGUI (folder)
   • SNDSPS2 (folder)
   • GAMER.OVL
   • LOADINGE.RAW
   • MKDA.PAK
   • MOVIER.OVL
7. In CDVDGEN Directory window, highlight MKDA.PAK and press delete or remove it using mouse
8. Drag newly built MKDA.PAK onto the Directory window
9. Save the project with File->Save, keep it around in case you’d like to install more mods and save some time
10. Choose Export iml file from File menu and save it somewhere you can find
11. Close CDVDGEN

Now open “iml2iso”, it’s a tool designed to convert the IML file listing into a working PS2 iso.

IML2ISO Steps

1. Once launched, click the … button near IML file path
2. Locate your previously exported IML file from CDVDGEN and open it
3. Press Start
4. Wait till the ISO generation process is finished, the resulting .ISO file will be stored in the same path as selected .IML
5. Done

Installing (old)

This section is for old mods that have .bat files!

Preparing game data

Create a new folder somewhere, copy MKDA.PAK and game executable (SLXX_YYY.YY file) to this folder from extracted game directory.

Place all files from mod archive here.

Run PatchSLXX.bat to patch the executable (make sure region is correct!).

Run ExtractPAK.bat to extract MKDA.pak file. This will extract the archive to the root of your current drive, so contents end up in X:\ps2dvd (X being drive letter).

Go to the extracted folder and replace files in art folder with the ones from the mod.

After you have done that, run BuildPAK.bat. An archive will appear in the root directory (ps2dvd.pak), rename it to MKDA.PAK and copy it to the modified files folder.

Move MKDA.PAK and executable file back to original game folder.

Build a new ISO from the folder (guide linked in introduction).

Once that is done, you can either play the modified iso on a real console or using an emulator.
