Ah yeah, this has been around a while. The previous three incarnations (Gold, Ruby, and Sapphire) were dumped recently at Kamming's Blog (I think?) Sapphire has Brandon's back sprites at the start of a fight and some other small consistencies, but it's otherwise the same.
Oh, and despite the really simplistic engine, it's much more fun than most unlicensed RPGs, including the Waixing Pokemon Red. Really, that's sad.
