veesem

veesem is an experimental V.Smile emulator. Game compatibility is generally quite good from what I have tested so far, though more features, a more advanced UI and better accuracy are future targets.

Command line options

• Usage: veesem [OPTIONS] CARTROM
• Emulation options:
  • -sysrom ROM - Provide system ROM (otherwise dummy ROM without boot animation will be used)
  • -pal - Use PAL video timing (default)
  • -ntsc - Use NTSC video timing
• Visual options:
  • -leds - Show controller LEDs at startup
  • -fps - Show emulation FPS at startup

Controls

Currently only the standard V.Smile controller is supported.

Build instructions

• Required dependencies: SDL2, OpenGL
• Supported compilers: GCC or Clang with C++20 support. MSVC is not supported.

Steps

1. Create a build directory and change working directory to it.
2. Run cmake .. -DCMAKE_BUILD_TYPE=Release.
   • When building on Windows, you probably need to specify the path of your SDL2 MinGW development package directory with -DCMAKE_MODULE_PATH, e.g. -DCMAKE_MODULE_PATH=~/SDL2-2.30.11/x86_64-w64-mingw32/.
3. Run make or whatever the equivalent is in your preferred CMake generator.
4. You should now have a working veesem executable.
   • For Windows, remember to also copy the DLL from the SDL2 development package directory to the directory of the executable. The DLL can usually be found in x86_64-w64-mingw32/bin.
