How to add emotes

I have always wanted to add my own emotes, I use to be able to do with BTTV, With just editing its code to my likes for just for testing, But he changed it in new versions that is reads from a json file which some reason dosent work for me. So is there anyway to add emotes with my on addon? If so can you tell me how?

There is no way to add emoticons to BetterTTV. Even if you did prior, only you were able to see and use them.

Well i use to be able to like by editing the code to my likes, But then it got changed to read a json file which some reason when i make my own json file and things, And use that it dosent work.
