Well I pretty much have no choice but to use SmashBox for the enemy textures; sucks since a decent number of enemy textures have CMPR format texture parts. If I use ASH, the enemy textures will get corrupted, all due to the fact that they contain effect PAC files inside.
Well you could do what I did to make Mario's blue Final smash, Extract the .pac file in the .pac file, Run It through Ash, Then reinsert the newly made .pac file with a hex editor.
