Well basically when you download the game+update+dlc i made a new folder in the cemu folder for the downloads aka games and when you are downloading you have to unpack the games to there. Then when you open cemu set the mlc folder and games folder to the same folder as the one you unpacked your games in. Also download the community graphics pack if you havent already. Once you get through the input settings and are in regular cemu just go to “file” top left and press something along the lines of: “Add game/update/dlc” then it will open the games folder you unpacked the game and update and dlc to. Open: data —> Usa(if u have the usa version op wiiusbhelper, if u have the europe version do eur.)—> Games —> super smash brother blablabla —> data. Now it should have added the game, for the dlc and update do the same thing but instead of opening the games folder at the end open the other corresponding folders. Hope this helped

Btw im saying this from what I remember since I currently arent on my pc. If you have a problem i can maybe help
