1) Open the Image Patcher utility and click the Select Image File
button located at the top of it. BROWSE your PC until you find the
PS2 game back-up image file you made, then select it and click on
the Open button... it should look similar to THIS screen shot now.
2) Press the Scan File button, and observe the results obtained in
the window below. Next, click on the Verify Version button and
if the DNAS Version is recognized by the utility you will see THISUN-PATCHED data below (varies based on the files found)... and
the Disk ID boxes will turn WHITE allowing for character input.
NOTE: If your image files contains a DNAS Version not recognized by
the Image Patcher utility you can try the Disc ID Insertor
instead, or wait for the next Image Patcher update to come.
3) In the WHITE boxes enter the valid Disc ID you have obtained from
your original PS2 game disc and click the Patch button. You will
now see a prompt similar to THIS showing that the .IMG files found
have been successfully patched with the Disc ID you entered in the
WHITE boxes. It's not necessary to Un-Patch unless the Disc ID has been incorrectly entered prior to pressing the Patch button.
4) Finally... burn your patched PS2 game back-up .iSO image file using
Alcohol 120% if it is a CD-based image as detailed HERE, or use
DVD Decrypter if it is a PS2 DVDR image. This is done by selecting
MODE->iSO->WRiTE, browsing and selecting your now patched
.iSO image & clicking the Decrypt Button below. Enjoy!
