Hex Edit 101

Is anybody interested in some time spent learning some of the ins and outs
of Hex Editing SH3?
I've learned a great deal thanks to so many here and time spent digging around.
But all the info is scattered, makeing it hard to learn for most.
I do not have all the answers, but I think I can teach most anyone how it
all works, how to spot what you want, and what connects what.
What do you think?
