You can write a Plugin, with all your smilies, you need...
so you have to look, how a Plugin is written (you could find some Smilieplugins in the Store) for example: pluginstore.woltlab.com/file/1958/
what you need is just a Editor (example Notepad ++) and 7zip to take it back to .tar ... and your smilies
