Doesn't need the help of AI for repacking. This format is quite easy to repack them. Only get all the files, put toggeter aligned with 0x10 and update the data size. That's it
The problem with this format are the extraction

Oh, got it. So in this problem we can only rely on our own hands XD

Found the offset values of each file. Now the problem is how to to get this values, as they don't seem to follow a general pattern. It's after 0x07, but this byte could also be another value, so...

chr041_00.e

ev_tl_00_000_00_v2.e

It's great that you are making progress!
I wish I could help you... But I don't know anything about this hex decoding stuff

I'm more skilled in linguistics or adapting the UI to other languages.
I wanna get major degree related to Localization someday, but for now I decided to take a gap year and just looking for a job.

Finally found the pointers to get that values, and then the offsets to the files.

Now i can fully extract all the files without problem. The only think i have to calculate are the file size.
These are the logs of the 2 cpk, with all the files magic header.
Also, i add an Imhex pattern file, so if anyone want can parse it. Ther's also a basic code to get the size of almost all the types of files for extraction.

Now i will create a basic file extraction and repacker to see if it works. My goal is to create a single python script that implements the *e files extraction, and also the other formats in madohack tools (*btx, *csb, *gim, *pac) because inside the *e files are more .csb file to unpack

Yoooo, this is awesome!! Can't wait to try out your script
