How to update crazyclient manually?

I know how to compile the client, I get his updates from ****** since there's no wait time, but I would like to know how to manually change it to the latest version of rotmg. Even if new sprites won't show, I just want a quick way to still be able to play right after a new patch

I remember doing this to really old clients but the method doesnt really work for more recent clients

You wait a couple hours and let me do it or spend a day learning how to do it.

In all seriousness, the client is updated by getting the current client and the client released before that and decompiling them. Compare the scripts in WinMerge and make the required edits in the client. Replace all assets (i.e. XMLs and spritesheets) with the ones ripped from the newest client. Compile and you're done. All in all it takes a couple hours to complete.
