Out of curiosity, I tried to "mod" the chinese mod to make it work on the english version but, after a week of pure torture, no luck, I gave up.
For anyone, more experienced, feeling motivated to do the same, here's my experience:
- First, in the english version, they went out of their way to "censor" file names and some variable/strings (For example, school -> uni or creampie -> pumpkinpie) and it causes a lot of problem. To keep things consistent, I stuck with the english naming convention and renamed the mod picture files and some of the javascript files (ExtasyCul.js -> extaCul.js for example). I also applied it to what I ported from the mod code.
- I then painfully compared the javascript and json files, one by one, to carefully port the changes over. I homebrew python scripts to find the differences for me, to speed everything up. The Common Events was the hardest part.
I can get the game to boot but it's not in a playable state, it quickly crashes and the list of issues is only going up.
The fact that the mod is based on a different version from the one I have is probably not helping.
Another thing to note is the chinese mod renames a lot of events, maps, etc... and I'm pretty sure it's one of source of crashes I have, despite the fact I did my best to stick to the english version names.
On the bright side, however, there isn't much new text content, maybe 40 new strings top, so nothing much to translate.
It might be faster to try to extract the english strings from the english version and patch them in a chinese modded version.
Anyway, I'm done for now.
