Problem with system.def editing

[-Ash-]

I started messing with MUGEN 1.0 screenpack and tried to customize it, the problem is, everytime i try change Char select and Vs screen sprites it doesn't work like intended, and also screw sprites from other sections, any idea on what could it be?

Select screen sprite must be indexed under 9000,1 with a 9000,1 palette number. Make sure the sprite is unique (change a single pixel if necessary) or it will be indexed back to its former palette number.
Same with versus screen. I use 9000,2 numbers for this one.

Thanks for the help man.
