How to (somewhat) update your RotMG Hacked Client

Before you change your client, remember that any new content that DECA releases isn't going to display properly.
This is a terrible idea and it should only be used when you are seriously desperate to play or just need to do a couple things before a realm release comes out.

Step 1: Find a flash decompiler. For this tutorial I'll be using JPEXS. Get that at Here

Optional: You will need Java 1.8.0 to run it. Get that here: Here

Step 2: Open up the outdated client .swf with the decompiler.

Step 3: Find com.company.assembleegameclient.parameters.

Step 4: Open it and find these two strings:

Step 5: In the bottom right corner, click on "Edit P-code". Change the value in the FIRST to the major version of the new client. (Example X16.0.0)

Step 6: Edit the SECOND to the minor version of the new client. (Example X16.0.0)

Step 7: Click the save button in the bottom right corner.

Step 8: Either save it as a .swf or try your luck with a .exe (not recommended though).
