Copy + Paste from BC.
It is for WiiChess (PAL):
"I made it for SMG using the tutorial from DaveMode and after finding the correspondent location I modified the main.dol for WiiChess too. I copy+paste the tutorial from DaveMode and changed only the location off that byte. Thanks to all that made this possible.
Here's what I did (in case it helps others)
1) Follow the first 9 steps in this tutorial:

*note: you won't need to download the Keysearch or DesWaD programs for this
2) Double click PARTITION (RTYP01)
3) Double-click SYSFILES
4) Right click main.dol and choose to "extract to file". Save it anywhere.
5) Locate your saved main.dol file and open in UltraEdit
6) Press Ctrl+G
7) Type in 0xC9613 and press enter. It will take you to the correct line
8) Change the 0C on that line to 04
9) Save your file and exit UltraEdit
10) Go back to Trucha Signer and right click again on main.dol. This time choose replace.
11) Find your new main.dol file and double-click it. A pop up window should appear saying file successfully saved. If you get an error, just close Trucha Signer and reopen it and reopen your iso file and try again.
12) Right click on PARTITION (RTYP01) and choose Trucha Sign It! (as a matter of fact I Trucha Sign It on both partitions)
13) That's it! You should now have an updated iso file that will not give you the Error 001!"
