Add an option to re-enable the Debug Save feature

This includes the ability to drag-and-drop save files onto the game
window, which this feature was likely meant to be used with.

 ## Building
 
-### CMake
+### Makefile
-
-This project primarily uses CMake, allowing it to be built with a range of compilers.
-
-In this folder, create another folder called 'build', then switch to the command-line (Visual Studio users should open the [Developer Command Prompt](https://docs.microsoft.com/en-us/dotnet/framework/tools/developer-command-prompt-for-vs)) and `cd` into it. After that, generate the files for your build system with:
-
-```
-cmake .. -DCMAKE_BUILD_TYPE=Release
-```
-
-You can also add the following flags:
-* `-DJAPANESE=ON` - Enable the Japanese-language build (instead of the unofficial Aeon Genesis English translation)
-* `-DFIX_BUGS=ON` - Fix bugs in the game (see [src/Bug Fixes.txt](src/Bug%20Fixes.txt))
-* `-DNONPORTABLE=ON` - Enable bits of code that aren't portable, but are what the original game used
-* `-DFORCE_LOCAL_LIBS=ON` - Compile the built-in versions of SDL2, FreeType, and FLTK instead of using the system-provided ones
-* `-DRENDERER=OpenGL3` - Use the hardware-accelerated OpenGL 3.2 renderer
-* `-DRENDERER=Texture` - Use the hardware-accelerated SDL2 Texture API renderer (default)
-* `-DRENDERER=Surface` - Use the software-rendered SDL2 Surface API renderer
-* `-DRENDERER=Software` - Use a handwritten software renderer
-
-Then compile CSE2 with this command:
-
-```
-cmake --build . --config Release
-```
-
-If you're a Visual Studio user, you can open the generated `CSE2.sln` file instead.
-
-Once built, the executables and assets can be found in the newly-generated `game` folder.

 * `JAPANESE=1` - Enable the Japanese-language build (instead of the unofficial Aeon Genesis English translation)
 * `FIX_BUGS=1` - Fix bugs in the game (see [src/Bug Fixes.txt](src/Bug%20Fixes.txt))
-* `WINDOWS=1` - Enable Windows-only features like a unique file/taskbar icon, and system font loading (needed for the font setting in Config.dat to do anything)
+* `DEBUG_SAVE=1` - Re-enable the dummied-out 'Debug Save' option, and the ability to drag-and-drop save files onto the window

 Visual Studio .NET 2003 was used by Pixel to create the original `Doukutsu.exe`, so these project files allow us to check the accuracy of the decompilation by comparing the generated assembly code to that of the original executable.
 
-This option is **strictly** for checking the decompilation's accuracy; CMake should be preferred in all other situations.

 ## Licensing
 
 Being a decompilation, the majority of the code in this project belongs to Daisuke "Pixel" Amaya - not us. We've yet to agree on a license for our own code.
