Hacking [Question] How to spoof CIA format NAND update components?

[MelonGx]

For example, I want to make a 9.4.0-21J Homemenu (0004003000008202) to be recognized as a 10.2.0-28J one after installed.
Is there any method or tutorial already written about it?

You mean "Change the version number(s) to" checkbox?
If yes, it doesn't work on everything not the latest then.
