ROM Hack Finding the Build ID for the cheats code

[Eiffel2018]

Beside of checking it in SX OS menu Cheat Section,
are there any methods to find the Build ID (of difference game update versions) from the nca or nsp file?
or how to make it by calculation?

If you have edizon overlay, open it and it will appear the game ID

As stated above - you can use Edizon, Edizon SE, Edizon overlay and maybe other homebrews.

Info is included in header of "main" file in exefs. At offset 0x40, 32 bytes. For cheats you are taking only first 8 bytes.

Excellent! That's exactly what I want.
Now, I can create a cheat code file without sending xci/nsp to the switch.

Hello, friend, how did you do it?
Are you use hactool to Extract xci or nsp files to nca, and Extract nac to exefs and read the biild ID?
I use NSCB to read xci's build ID but it looks like not always correct.
Are you willing to share your tools or implementation ideas.
