replace cash_pc.txd in levels\GLOBAL\CHARPAK with this mod's .txd. (make a backup)

Alternatively if you have the PluginMH installed, you can just create 
a .ini that leads to a custom texture of Cash by changing the .txd used in the ini 
itself (works with several mods, just make unique inis that point to different 
.txds).

(Create a copy of the !default ini and change the function where it calls for 
cash_pc.txd and change it for a .txd of this mod, make sure the txd's in the
same location as the default cash_pc.txd, you can also do this for all
the versions of this mod and other mods that modify Cash's Textures, don't
forget to save the new ini under a new name that isn't !default and make sure
to rename the name function inside the .ini, so that it shows up under a unique
name in the menu)
