Thanks for downloading this mod! This is a first for me, so hopefully I start getting more into this soon!

The black Dr. Mario skin .pac and .pcs files are in FitMario11, so rename the .pac and .pcs files provided 
to the same thing if you want to directly replace that skin.

Instructions on how to change the CSP and BP:

The black Dr. Mario skin has the key number of 007, so that's the number you have to look for to replace the CSP
and BP. The stock icon is included for if you put this skin in over any other Mario skin.

Hope you enjoy!
