Thats awesome, I have played some of the touhou games (I specially like the bullet hell ones), but I didn't know there were enough characters so that they could replace all the pokemon in the red version.
im playing it on my samsung galaxy 5 using myboy! gba emulator with bluetooth link enabled. i highly recommend u to play it. u need a clean copy of pokemon red (U)! and the ips patch from here: animackid.wordpress.com/touhou… check sanae's website for moar info. i still cant beat touhou 14 DDC. my rival on that hack game is my sister. she's more advanced in the game than me and that makes me jealous.
