I wonder how many version are there? I found those:
- Touhoumon : the very first one, from Pkm Fire Red.
- Touhoumon Emerald : hacked from Pkm Emerald, not really special
- Touhoumon Gensokyo : looks like it's from FR also, but they made a new map.
- Touhoumon Lunatic : from FR, map is slightly changed but it's freaking insane.
- Touhoumon God Mode : no idea if it's real or not, but looks kinda... unfair. Whoever made this may just want to buff his favourite girls.
And there is no 100% good english one yet. I'm playing Yui+Aqua work atm but it has something wrong, like Lunatic move just kills you, or you can't catch Eirin, Kaguya, Mokou and the game itself is quite easy.
