Let's refine:
1. Get the source code (D3BFG/RBDOOM) and compile it (as debug).
2. Create 'base' folder into appropriate folder (eg. Win32/Debug/base).
3. Put into 'base' our own folders (af, def, script, maps, newfonts etc.) and default.cfg.
At this moment custom game resources are not binarized, map created in D3 Editor/Radiant, and original game resources are not present.
4. Run .exe.
After that I have a black app window with working console.
5. Type 'map game/testmap.map' (also try 'dmap game/testmap.map').
After that I have a black app window. Console still working.
Your assets should be binarized automatically on map load. If they don't get binarized, something is wrong.
This moment is not clear.
What about fs_bulidresources, buildGame, fs_loadPriority etc.?
No need to use it in this case?
Will testmap.resources be created automatically (via 'map' command) in maps/game/?
