I think this IS the Jast version in the OP, actually.Does anyone have the JAST version of the game since the watermark removal patch is broken for the steam version?
Also, going by what someone else said here, the Steam "vanilla" + Jast uncen patch actually results in the same, watermarked experience. I'm guessing that some very enthusiastic Chinese guy did a watermark removal for the Chinese version, but it won't work for the English version. (the watermark remover cg.npk is like 1/4 of the size of the English version's cg.npk... dunno how they have managed that lol)
Also, going by the one scene I've made it to so far, it doesn't seem to be as bothersome as I had previously feared.
