for SSBC 0.95 and CMC+ 7 add to fighters.txt:
Scorpion
and increase top number by one. Then in CSS.txt put the next highest number somewhere.
If you use CMC+ v7: put the stuff into the specific folder (data, fighter etc.). After this put the content of "for CMC7 & CMC8" into the game-folder replacing the stuff of portrait, mugs etc.

for SSBC 0.94:
Scorpion
Scorpion
Scorpion
Scorpion
MK

and delete the 4-5 lines of the dat-file including the names and seriesname.

For CMC+ 8:
Same procedure as for CMC7 BUT after all this you additionally add the content of "forCMC8" into the game-folder adding stuff and replacing dat-file - otherwise colour-palettes won't work.
Enjoy!
