Missing 11eyes charset file #4

Hello, I think this is the right project for my use case.
I've noticed that the original KiriKiri2 / KAG PC release of the game has a very easily editable script since it's in plaintext, though you still have to leave everything in shiftjis encoding, otherwise it becomes stuck in a loop.

However, the 2009 CrossOver release (sort-of HD All Ages remaster too) of the game is only released for Xbox 360, is using an early build of MagesEngine, and the main executable is named adv1.exe while the SteinsGate Xbox 360 release has the name adv4.exe, and the Xbox version of 11eyes uses LNK4 dat archives and AFS archives.
Title ID of 11eyes is 465607D4, SteinsGate Xbox 360 is 465607D8.

So, my main observation is that the script files are in SCR extension and always begin with SC3.

I've also noticed that the older SciAdv.Net project did have a charset file under the "ElevenEyes" folder (in the sgvita-hack branch), but I can't get that thing to compile with the 2022 version of MSVS. and I've also noticed that while there's a 11eyes.yaml file in this project's mgs-spec-bank folder, there's no JSON charset file for it.

What can I do to get a workable script to TL? I already have the full resources needed from the krkr2 version, so I'm guessing it would be just porting those into this version.

Hopefully there's going to be an advancement here.
