jDoom is a program that allows you to play Doom II over the internet that's running in a Quake 2 engine. This basically means you can now strafe, mouse look and jump in Doom!
To do this you need the following:
A copy of the Doom II WAD file
All of the following programs/files:
Doomsday Kickstart 2.09 - Front end to jDoom
jdoom_mpack - Model files for Doom II WAD
glBSP - Batch program to fix mapping errors in WAD code
You must install the three files into the same folder. Doomsday Kickstart is a front end to jDoom that allows players to select various WAD files such as Doom I and other games like Heretic.
To find out how to to install this little lot go to the Doomsday web site at:
