Updated
Launcher v0.7a5 dev with various changes and things related to all sort of things (almost finished v0.7b, but few things are hidden).
This update is mainly for
THAT issue, and it includes the addition of merging between new languagedata format ("Merge Data v2"), conversion from and to new txt format.
Currently there is no conversion from old format to new format, but you can convert txt => xml/xlsm, then copypaste similar tables, or rename tables+columns (either in old or new format) and merge those, you might also add KR columns to scheme as keys and then merge based on that, etc. etc. basically there are many variants, but none of them is perfect. Unfortunately not all tables keys were copy-pasted by devs.
Check out languagedatav2 in
Scheme. I'm not sure yet if Region is key or value (I've asked volunteer to test it, but so far I had no reply regarding that test), so it might or might not crash the game if you edit it...who knows
xml to txt and txt to xml currently are tied to languagedata v2 scheme, so be careful when changing scheme, also understand that you're not going to convert v1 to xml and then proper txt version
on the other hand you can covert txt => xml => xlsm without any problems, but it won't be equal to current(old) xlsm version, if you get what I mean.
You can redownload it through the same link. It also shipped with the latest scheme and KAMI project.
P.S. Confirmed that Region is not a key, so everything is correct.
