+# D2DF-SDL
+[Doom 2D Forever](https://github.com/pss88/DF) adapted for use with the FreePascal Compiler and ported to SDL 1.2.
+
+# Building
+
+## Requirements
+* FPC >= 3.0.0 (with the "sdl" package installed);
+* FMODEx >= 4.44.25;
+* libenet >= 1.3.13;
+* SDL >= 1.2.15.
+
+## Instructions
+### Windows
+Create two directories, "./Bin" and "./Temp". 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.
+### Linux
+Not tested yet, but running
+```
+fpc -MDELPHI -O2 -FE../Bin -FU../Temp Doom2DF.dpr
+```
+in the "Game Source" directory should probably be enough.
