I'm having trouble enabling DLC with SSB, I dumped my disc and have "aoc0005000c10144f000" folder. But inside it's nothing but dummy_content.txt and none of my fighters are unlocked using loadiine. I have the DLC option enabled and the aoc0005000c10144f000 folder is in the game folder.
0005000010144F000 = US Smash
0005000E10144F000 = Updates
Make sure you have added the latest Update and activated it in Loadiine.
Works now?
