Editing updated wad files

[Sladescowl]

What do I need to do to edit the updated wad files that I'm wanting to edit. Before the update from the final demo I used to edit my wads using SLumpEd and setting the IWAD to the srb2JTE.wad file.

Now I have no idea what to use as the IWAD, what do I use as a replacement for the IWAD or do I have change the editor.
I'm not really in favor of changing the editor as I'm used to this one.
If it's a "I have to change" scenario give me an name of an editor that's close to SLumpEd.

use srb2.srb

Why did you use "srb2jte.wad" as the IWAD in the first place?
