"Wtf, I thought I closed this yesterday ~_~ I guess PC borked. But yeah, those are ROM hacks, not official games. Actually, I'm pretty sure there's a thread about it in the ROM Hacking forum."
PKMN Acanthite is not a ROM hack, just to let you know...
It's a fan-made game. Calling those games as 'ROM-hacks' or 'hacks' insults the game makers.
Good day~
