The only websites I can find about Pokemon Halomon are written by some guy who is IN NO WAY affiliated with Nintendo who thinks he is going to be able to sell a Pokemon game for $.50 legally. (Also, by the way he writes he sounds like a 14 year old who is making everything up). Oh and by the way, the game is completely homophobic from what I have been reading.
So to recap: No affiliation with Nintendo (stealing from their company) and homophobic (yeah, there is no WAY Apple or Nintendo will let that go out to the masses).
