Ok.
Out of that, I've found no other glitches besides the Super Shadow changing when being grabbed.

Last test result:
No freezing problems at all quite yet.
Tried about 5 Brawls facing 1 single opponent.
Now to test with 4 opponents.
Gotta tell something a little funny:
Whenever I'm Super Shadow, a new Smash Ball spawns.
Does this mean Shadow's Final Smash can work at the same time as others?
If so, it's time to experiment.

well if you played with the wario v2 shadow when shadow gets the smash ball he spams the crap out of chaos sphere the only why to fix that was to exit the final smash but super shadow is on a timer some what like robs final smash but if you get the smash ball with super shadow it should only reset the timer but i may make another final if super shadow gets the smash ball
