It's been quite some time since the last secret. But then again... it's been quite some time since I've been in a new game. Regardless, this secret has one purpose alone... and that is in regards to Project Metroid. You know... that page that you found this secret through?
Regardless, on with the show. Thankfully, VBub has created an image that indicates what is clicked on inside the Project Metroid Controller. Just follow the blue line and click on what it tells you to. Hell, it's so simple a Rinka could figure it out.
Although, it may be in your best interest to know that the passwords can be obtained over here. It's now just a matter of putting them in, following the instructions given here.
