It should be noted that you will DC if you go into RIFTS and only did this, it's because you're missing game assets and the servers is wondering why you don't see shots/don't get hit by shots from the snowmen.
Hello! So I saw a thread in posted in 2018 by user Swagtown, and I decided I would do a little bit of a repost scenario with clarification and pictures as a step-by-step walkthrough on how to update any client to the current version to play with. WARNING: This may be unsafe, may get you banned, but if you want to play with a client and not wait possibly a week for a release, this tutorial will show you how.
--Precursor: Tools you will need--
-JPEXS Free flash decompiler
-Old client of your choice (I used 059's client)
-Fresh .swf of ROTMG.
--Step 1: Gathering Information--
-After you install JPEXS, open the fresh ROTMG .swf (Named AssembleeGameClientXXXXXXX)
-Open directory trees to "scripts\com\company\assembleegameclient\parameter s\Parameters.as"
-Find "RANDOM1:String" and "RANDOM2:String" values and copy them to somewhere like notepad.
--Step 2: Updating the client--
-Open your client .swf in JPEXS to "scripts\kabam\rotmg\messaging\impl\GameServerConn ectionConcrete.as"
-Find the string "_loc1_.buildVersion_" and change it to the current version by using the "Edit P-Code" button on part 3 of the image below. Current versions are publicly availible on RealmEye.
-Now browse to "scripts\kabam\rotmg\application\impl\ProductionSe tup.as"
-Find the build version as pictured below and set it to the current build version using Edit P-Code as done before.
-Then browse to the same area as shown in step 1 but in your outdated client and change the values of RANDOM1:String and RANDOM2:String to the values you copied earlier.
Now you're done! Save the swf file, maybe as "whateverclient-edit.swf" and open it with Adobe Flash Projector!
Closing Statement: If any update introduces new content, the new content sprites may not appear as you are technically using an older version of the game.
Thank you for reading my tutorial. I hope I could have been some help for those who are impatient and just want to play. Remember to say thanks on the post if it helped any!
