Works with Custom Smilies 2.3!
I use Custom Smilies 2.3 plugin. However, I prefer the Yahoo! Messenger emoticons. So, I did some digging, found them all, then tweaked my plugin to use those emoticons. Yahoo! Emoticons for Custom Smilies 2.3 is a tweak for the plugin Custom Smilies 2.3 found at http://goto8848.net/ . This updates files within that plugin so that you can use Yahoo! Emoticons with your WordPress installation. To save some time for anyone else who wants to do this, I’ve made this tweak available for everyone.
Important: If something breaks, please keep in mind that I’ve only added smilies to an existing plugin. If you have problems, I recommend uninstalling this plugin and downloading the original plugin to see if it works first: http://goto8848.net/projects/custom-smilies/

Replace the smilies with the original versions from previous versions of WordPress.
Added bonus: Disables all “emoji” functionality in WordPress 4.2 and above.

Classic Smilies

I have been using this plugin and I proudly recommend to everyone.
PRO
- It improve performance by removing inline JS and reducing HTTP requests.
Cons
- Smiley images shouldn't be look dull. It could be appear clear like Original.
