Saw a question regarding this, threw this up here to let people know how to do it. The person who made the thread was Zoruathelittlefox, or funkylaurens. That's the guy who made that thread.

I also want to further warn that using the PMU Source can potentially make you vulnerable to people trying to hack your game, as it's not very secure. Use at your own risk.

If you need help with the source, I am not your guy, but you'd probably wanna look further into the thread above.
