"Justi-Derp" is a modification of "Justified Classes", it made various edits to the pre-existing classes to make them chaotic and funny, and it was pretty neat.

But it's been stuck in the past for a very long time, not only requiring a older version of MM8BDM but even a older version of Zandronum D:

That's where I present to you JustiDerp XDX. This is a port of JustiDerp that allows you to play this awesome mod in the newest version of MM8BDM! You too can experience the goofiness of this mod for yourself and for all future versions of MM8BDM to come.



But this isn't going to be just some port; JustiDerp XDX will include even more classes than the original and even some content from JustiDerp Neo! a JustiDerp edit that changed some attacks for some classes

All new content as of v1:
Rock Class!

v1 Presources (load this first!)

this is truely my favorite class based modification.
Also, the v5 => v6b porting only in a few days expert
