Can you share a program for unpacking and packing files?
I want to translate into another language...
If you can read Japanese, you can use the
localization extender plugin by Henry1887, and
here is the decryption / encryption plugin also by Henry1887.
I did write my own programs, but they have no instructions whatsoever, so they are really hard to use, and I didn't handle exceptions, so they would crash if not used correctly... Besides, the Unity Editor (more than 10 GB installation, and you need an account for it) is required to generate all 189 assetbundle files... I really can't recommend you working the way I do it, just use the plugin instead.
If you can't read Japanese, give me some time to finish the English translation. The original English translation really isn't that good... It feels like it was machine-translated, maybe with some manual fixes here and there. I'll try to finish my English translation as soon as possible, then I could export it with the plugin for it to be used as a base for translating into other languages.
In fact, if you replace the files from my preview patch, you can do that already. Be aware the translation is incomplete, and I keep changing some of the texts to fit into various UI locations or for better clarity. I should be able to complete the translation for everything except the gallery by next weekend.
