I thought i would share this old gem I used to use when i was first learning how to edit mugen.
It's an old Mugen tutorial blog from 2009 with many useful tutorials simple to read and understand.
It covers a wide range of topics. Everything from how to rip sprites for mugen to how to add groove bars and super jump into characters.
This is some old useful information that and beginner of mid range user should use and learn before it is lost forever
