Here is how to do the RABCDAsm bits.
-Download RABCDAsm
-Copy everything in RABCDAsm into a new folder on your desktop (for ease of use)
-Copy your client(.swf) into the new folder on your desktop, call it rotmg.swf (for ease of use)
-Run command prompt (start + R, then type cmd, click ok)
-In command prompt, type "cd desktop\new folder" (or wherever you put the files)
-Type "swfdecompress rotmg.swf"
-Type "abcexport rotmg.swf"
-Type "rabcdasm rotmg-1.abc"

-Leave command prompt open
-Now go find the file you want to edit (I am going to do edit the file to reposition the 'Rank' overlay)
-Open it with Notepad++ (or an alternative editor)

-Do a search (ctrl + f) for the part you want to change (I am looking for the first place it says "getproperty QName(PackageNamespace(""), "_-h-")"
So I searched for "_-h-", and clicked next until I found the right part

-Make changes (in my case, adding some code below it)

-Save it
-Go back to command prompt
-Type "rabcasm rotmg-1\rotmg-1.main.asasm"
-Type "abcreplace rotmg.swf 1 rotmg-1\rotmg-1.main.abc

-Now the .swf file in the new folder on your desktop should be updated.
*note* after doing this, the changes I made in yogda at the start (to increase view (setting pushbyte to 16) and remove the black grad bar (adding pop, pushnull) are reset, so you will need to redo those.
