Reminder, this ONLY works on Windows XP. Believe me, I tried it on vista and it didn't work.
You are going to need the help of Daemon Tools to use this.

Instructions:

-A setup should start up and follow instructions (just paste password when password is asked)
-Hope it works, credits go to TEAM ZERO
I think it has something to do with spoiler being put first. My post also didn't show up for me when I did that but after adding some text before the spoil, it works. Don't know what this is though. If you want to look at the stuff that are not showing up, just click quote on the post and then copy the link directly.
