ROM Hack What did I do wrong?

[OldGlass]

I'm trying to install the Justin Bailey mod for Smash 3DS, but the mod won't load. The only mod that loaded for me was the uncensored Corrin mod, and I applied the patched by dragging the SaltySD file in the uncensored Corrin's zip file to my SD card, and it worked. For the Justin Bailey mod, I dragged the smash folder into the SaltySD folder. So, every thing should have worked right? What am I doing wrong?
