Decompiler Tools

Decompilers are tools that convert files to their original state, that is to a state before compilation. All decompiled maps are a huge pile of mishmash, it is impossible to fully recreate an complex map into its pre-compile state. This is because decompilers guess how something would be and recreate it. This naturally produces a lot of unwanted things and errors. Only use decompile to learn something, decompiling and editing an map is a lot of work and would take much more time than actually making the whole map from 0.

It is best to use BSPViewer or Crafty for this due to their entity exporter and viewing mode.

Bsp2Map is a good decompiler because it can decompile almost any BSP, but it has some weird thing and it makes every wall 1point tick.

MDL decompiler decompiles models into animated sequences and mesh files, also extract the textures.

wad2bmp extracts textures and converts them indo bitmaps from BSP or WAD files.

WinBSP 1.2 is a very good and pretty accurate decompiler. This is old version v1.2

WinBSP 1.4 same as above, only updated.
