>How to play?
Run anchor.exe, japanese locale is advised so you don't run into untranslated text.
If you wish to manually update, delete old files aside the sav folder to avoid any bugs.

You could try your hand at translating dialogue, there's guides currently in TW folder(in #Translation) on what to do, since I mostly played TW, not sure if it that folder exists in other games.
Another guide from threads is:
1) Download an IDE. VS Code, for example.
1a) If using VS Code, install the EraBasic addon
2) Select UTF8 encoding
3) Open the ERB files and edit them
That way you can now edit files without much trouble.
The path for files to edit is usually the ERB folder:
K: ERB/口上
TW: ERB\口上・メッセージ関連\個人口上
You can also report bugs or typos when you see them.
If you'd like to either edit or add your own portraits for 2hus, the files are located within the resource folder as webp also known as the worst filetype known to man.
