  • Build and link files in the /src directory with cc65/ca65/ld65
  • Works with Windows and Linux (including WSL)
    • Edit in Windows, compile in WSL, etc.
  • Execute emulator from VS Code
  • Works with Makefiles
    • Build with Make
    • Test with Make
  • Many configurable settings that allow for very flexible usage.

Where to get it:
