Doom 2D Forever adapted for use with the FreePascal Compiler and ported to SDL 1.2.
This port has been abandoned in favor of the SDL2 port, which is currently in development. For further information, see the official forums.
Run build.bat. If it builds fine, the executable will be output to "./Bin/Doom2DF.exe". Don't forget that it will require SDL.dll, FMODEx.dll and ENet.dll to run.
Run
fpc -MDELPHI -O2 -FE../Bin -FU../Temp Doom2DF.dpr
in the "Game Source" directory.
