Well, if it's anything like gPotato's servers were, translating the game into English should be as simple as decrypting the files to extract the script/db/ folders, and translating the strings in the appropriate files. At least, if overwriting the files in the /script/db/ folder in the game directory still works on this version. A direct copy/paste of gPotato's files doesn't look like it will work, though; I'm seeing a few items that I definitely don't recall seeing on the gPotato servers, so I doubt they'd have translations for them, assuming the IDs for the items are even the same in the script files.
I've got more hope for the files for hosting the private servers being released, though. A Chinese private server for a game which still has an official Chinese version in existence doesn't sound too hopeful. And even private server files in Chinese would be preferable to no private servers/files at all.
Still, for now, private server + no files > no server at all, even if it turns out to be short-lived.
