NOTE: This is a work in progress commit. It includes debug and test functions and some features that existed before might not even work. It is not finished and not very well tested. So it's warning to NOT use this for everyday playing! This is target for developers to look some stuff up that I was working on. See also my post on gbatemp for more information.
