Importing Levels

[LadyVader1138]

I have been wanting to do a project for a while: importing Doom's maps into Doom II and sprinkling in monsters (and the SSG) from the latter. The problem is that I have no idea how to quickly and easily put the Doom levels into Doom II for level editing.

NOTE: This is a personal project and have zero intent on distributing it for legal reasons.

Adding to what Nevander said, Realm667 has Doom Textures for Doom II.

 

If you want to play this in a port that doesn't use MAPINFO, then you will have to rename the maps MAP01, MAP02, and so on.

[Nevander]

In SLADE, copy and paste all the Doom 1 maps into a new WAD. The map names can stay as ExMx. Open this WAD in GZDoom Builder under Doom 2 config. Make your changes.

 

You will be missing some textures. They will need to be pulled from the TEXTURE1/PNAMES in DOOM.WAD.

 

When finished, create a MAPINFO lump in this WAD with your maps and define your episodes and Doom 1 maps. You can probably safely copy the MAPINFO from gzdoom.pk3.

 

Finally, load it as a PWAD with Doom 2 as the IWAD.

 

EDIT: Don't forget the music also.
