Hi! Exam just passed so I got my free time to online~
I just want to talk about Togainu no Chi game. If you got problem while installing the game, you should follow what this blog had said. It's what I called a complete guide.
Why Daemon Tools? I don't know either. Sometimes I tried mounting it with PowerISO, it didn't work even though I already changed the computer language to Japanese. So I recommend you to download Daemon Tools if you want to play Nitro+CHiRAL games like Lamento and Sweet Pool.
Oh, PowerISO works on SPRAY games with no problem occured ;)
By the way, I just REINSTALLED Togainu no Chi. Don't understand? That means I HAVE TO PLAY IT BAAAAAAACCCCKKKKKKK SJDKSAHFIEWFHIDJMCUWIJDMWDXBSAS!!!
