Navigate to the .CIA you wish to extract files from.
Select it and select CIA image options... > Mount image to drive.
Select the first folder, it should be called something like 0000.00000002 (names vary depending on the title).
1. Make sure that the ROMFS is about the size of the installed title. If it is not, then the actual game content may be in another folder.
Select the files that you wish to extract.
1. I.e. if you need a full romfs.bin, select that. .code (code.bin) is stored in the exefs folder.
2. If you need specific game files, you can navigate through the romfs folder to find specific files.

Go to where the CIA is located, open it > CIA image options... > Decrypt file (...) > Decrypt inplace.
1. You can choose to decrypt to /gm9/out but you will need to navigate to the decrypted title.
2. If it does fail, then the title is already decrypted and you can move on.
Open it again > CIA image options... > Mount image to drive.
You should see a folder (or two if the title has a manual) and .apps with the same names. Select the .app > NCCH image options... > decrypt file (/gm9/out).
1. If you have multiple, go through each .app and make sure there is not a Manual.bcma inside of the romfs (the manual NCCH image is typically around 3mb, so if you have another .app which is obviously larger, go with that one).
2. If it does fail, then the title is already decrypted and you can move on. If it didn't fail, then you are done.
Select the same .app again and select Copy to /gm9/out.
Rename the .app to have the file extension of .cxi.
Open in Citra and hope it doesn't crash (I don't know what to do if it does crash).
