You shouldn't need to convert BBM, there is a CIA already included in the download. If you convert it to CIA manually it might not work.
Ah I wasn't clear bbm works fine. The games however do not. It just tells me to shut off. I've tested ocarina and new super Mario bros.
EDIT: Okay so i tested someone elses cia and that works perfectly fine, so it's an error on my end converting to cia. Do you know what i could've done wrong Jdbye-Sama?
