Just like the home menu.
But check if it has multiple cxi (content files) before building it into a cia again.
But I don't think it has more than one. So you are good to go just using the Home Menu things.

ErrorDisp is the same for all regions. So the last version is

Extract it. Use the tools in this thread, and for know his ID cxi, use this code in a bat file :

ctrtool -i -y --content=c --tmd=tmd NAMEOFYOURCIA.cia

Make you sure you have CTRTOOL in the same folder of your CIA and the bat file.

After that, just edit the file Part1.bat and soon the Part2.bat with your ID

Don't understand

Put the tools in the same folder with your CIA and make an other bat file (so you make first a txt and after you rename to bat). You put in this file this code :

ctrtool -i -y --content=c --tmd=tmd NAMEOFYOURCIA.cia

After that, execute this BAT and now you have a file like this "C.0000.00000082" but with an other number, it's your ID...
Replace just with your ID in the part1 and part2

I got it : c.0000.0000000a

 

[Ewin]

I got it : c.0000.0000000a

So replace in the part1 and run, just replace 82 by 0A
