Here is a version of E1M1 that I created using the NEWDEU editor. If you
haven't tried the editor yet, do it NOW!! If you tried and found it
confusing, just keep at it, there is a lot to learn. Enjoy.

To use this level type:

DOOM -FILE JLF-E1M1.WAD

This makes a temporary change to the DOOM WAD file in memory only, so your
original WAD is not modified in any way.

Cheers...
