SGDK Usage

To be properly recognized by SGDK makefile, you need to respect the following constraints in your project folder:

• source files: should be located in / (root) or /src directory.
  • .c = C source file
  • .s = 68k GAS assembly source file
  • .asm = 68k assembly source file (other format)
  • .s80 = Z80 assembly source file
• include files: should be located in / or /inc directory
  • .h = C include file
  • .inc = assembly include file
• primary resource files: should be located in / or /res directory
  • .c = C source file
  • .s = 68k GAS assembly source file
  • .res = resource definition file (compiled by Rescomp tool, see bin/rescomp.txt file)
• others resources files: can be located anywhere while you are referring them correctly in your .res file
  • .bmp = image file (indexed colors only)
  • .png = image file (indexed colors only)
  • .vgm = VGM music dump file (Megadrive only)
  • .xgm = XGM music file
  • .wav = WAV sound file (used for SFX)
  • .bin = binary data file
  • read the bin/rescomp.txt file to have more information about supported resource files.

Then to compile your project you need to use the following command directly from your project directory:

%GDK_WIN%\bin\make -f %GDK_WIN%\makefile.gen

Normally you should obtain a rom.bin file in the out directory that you can load in an emulator (or directly on the hardware if you are a lucky owner of a flash cart).
