I didn't even know an Animal Forest injection was out. I so got to look for it.
And there is an English translation patch out there. So putting all those in a wad seems easy.
But I heard the English translation patch was really crappy. The person who was kind enough to try translating, really didn't get the whole game done. Like when you try talking to the police officer, the captions are Chinese.
But that was a while ago,maybe they updated it some more.
EDIT: I am currently working on putting the patched version of it into a wad. Will experiment and get back to you.
