SDL 1.2 (included) Doom shareware Wad game file (not included) This
version is build upon Doom Legacy 1.42 source using SDL 1.2 and OpenGL
support. The game has been build on mac os x 10.3 and not test end on
older versions ( and I won't)
Bugs - networking currently not working.
I tested this all version They work all way to Mac OS X 10.5.8.

Doom Legacy can run any of these games. Doom 1 shareware and Doom 2
and Ultimate Doom and Chex Quest 1 and Heretic shareware game and
Heretic full game and Freedoom Doom 1 and Freedoom Doom 2 and Final
Doom include is Ultimate Doom and TNT-Evilution and PLUTONIA
Experiment. The manual read files are included. Chex Quest works will
works both ways. If you renamed to doom.wad to chex.wad or chex1.wad
the game will play or leave files alone as doom.wad and doom3.wad.

You need wad files for these games. The files has to be in same folder
for each game. But you can put each game in separate folder. The game
will find the game. I upload the screen shot of folder of each game in
separate folder and screenshot PLUTIONIA AND TNT from Final Doom.
