Thanks sugaryling for your comments! I'm glad to know that my tutorial helped somebody. And thanks Darren for filling in where the tutorial didn't. I'm gonna update it so that it mentions the storage card flashing method.
I put the site up to use as a portfolio piece. The fact that it helped someone shows that the info is correct, at least
.
EDIT: I've updated the guide to include the storage card flashing method. Thanks again for trying it out!
