How to install a DDLC mod?
Installing a DDLC mod involves adding the mod files to the original game files or replacing some of the original game files with new files. This process is standard for all mods and becomes very simple when you have a feel for it.
Locating the original files is different depending on whether you use a standalone copy of the game or the Steam version. A standalone version is easier, so we recommend this approach if you’re unsure where to install your mod.
You may need a program to open archive files, such as WinRAR or 7ZIP. You can download and use these for free.
Download a fresh copy of the game from http://ddlc.moe/ or copy and paste an unmodified copy of the game on your computer.
(Optional) Rename the folder to match the name of the mod you’re installing.
Inside the folder, right click DDLC.app and choose “Show Package Contents” from the drop down menu.
Navigate to Contents > Resources > autorun > game. The autorun folder is the same as the top level folder in the Windows version of the game, where game files and character files can be found. (Instructions from here are the same as Windows.)
In a separate window, open your downloaded mod folder and navigate to the mod files (likely in their own “game” folder).
Copy the all mod files from the mod download to the game folder, replacing any files with the same name as needed.
Launch the game, and you should see that your mod is installed!
“I followed the instructions, but I’m not sure if the mod installed correctly or not. How can I double check?”
When you launch the game, it may not be clear if you’re looking at the base game or the mod you’re trying to install. The easiest way to tell is if you have finished the base game on the computer you’re playing on. Normally when you launch the game at this point, you’ll be immediately greeted with the letter you see at the end of the game. If you see this letter on a non-modded copy of the game and don’t see it on the copy where you just installed a mod, you have succeeded—if you see it on both copies, you have failed.
If you haven’t completed DDLC on the computer you’re playing on (perhaps because it’s new or you simply watched a playthrough instead of playing one), turn on the base game and click through the splash message. From that point forward, you should be taken to the title screen when you start the base game. When you launch the modded copy, do you see a new splash screen or the normal title screen? Some mods use the normal title screen, but you may see the title of the mod in the lower right corner. If you don’t see a splash screen, a mod title, and clicking New Game takes you to Sayori greeting you on the first day, your mod install has failed.
Note: There is at least one mod in existence which pretends to be the base game until you hit a certain point before revealing itself. However, even in cases like this, you should see a unique splash message at the beginning. If your mod install has failed, double check which files you copied to what location.
Did you put the mod download’s “game” folder into the game’s “game” folder instead of moving the files inside?
Did you copy files from the top level instead of the game folder, or place them in the top level of the game’s set of folders?
Keep in mind, you’re looking for a small number of .rpa files or a larger number of .rpy or .rpyc files and a mod_assets folder.
Enjoy your mods!
