WAD Editors
From SRB2 Wiki
A WAD editor is a program designed to make editing WAD files easier. It simplifies the process of creating WAD files by either adding a graphical user interface or by doing raw calculations for the user.
The below is a list of WAD editors of different kinds. The SRB2 community, in general, uses one of the following WAD editors.
Map Editors
SRB2 Doom Builder
SRB2 Doom Builder is a map editor tailored specifically for use with SRB2, and is therefore widely used. It is maintained by Oogaland, a community regular.
WadAuthor
WadAuthor is an 11-year-old map editor, spartan and quirky in some aspects, yet slightly easier in others. It stands unmaintained now, though some like it for what they see as a simpler interface.
DeePsea
DeePsea is a shareware Windows-based map and lump editor. The demo version will load, but not save, maps with more than 800 linedefs and/or 1200 sidedefs. This restriction can be unlocked with pay. The lump editor is unrestricted.
Doom Builder
Doom Builder is a Windows-based open source map and script editor designed for Doom games. SRB2 Doom Builder was built on top of Doom Builder.
Yadex
Yadex is a map editor for Linux. It is unique for this reason and provides alternatives for Unix users who don't want to use WINE.
SLADE
SLADE is a recent map editor for Windows, with features comparable to Doom Builder as well as newer ones.
Lump Editors
Be sure to know that with a Lump Editor, you can try to open more than just a WAD file. You can, for example, open a PLR file, which is where the Sonic, Tails, and Knuckles sprites are located. On the Open window, type in the box sonic.plr (or the file that you want to open) and you'll be able to edit it just as any other WAD file. Just remember to keep a backup first.
XWE
XWE is a Windows-based lump editor. It's quite powerful, but it also has major quirks.
SLumpEd
SLumpEd is an open-source Windows-based lump editor that is quite comparable to XWE. It doesn't have the bad quirks XWE has, but it's prone to other bugs.
Lumpmod
Lumpmod is a command-line lump editor for Windows, released under the GNU GPL. It's very powerful, since batch scripts can be written for it. However, it only handles moving around of lumps and not actual formats.
Wintex
Wintex is a rather antiquated Windows-based lump editor. It is powerful, but very old. Since it's a 16-bit program, it won't work with the x64 editions of Windows.
WADMangle
WADMangle is a recent lump editor for Windows, released under the GNU GPL. It is highly extensible using plugins.
Miscellaneous
CleanWAD
A small utility that processes a WAD file and optimizes it as much as possible. In other words, it reduces the size of the WAD file. XWE has this feature built in but it might not be as effective.
ZenNode
A very widely used nodebuilder. It's included with SRB2 Doom Builder and is enabled by default. Users of other map editors can download ZenNode manually.
ZDBSP
ZDoom's internal nodebuilder, which, while works, causes some graphical glitches on bigger maps.
