Examples

  • I'm also thinking of switching to a "dirty buffer" approach with the text mode support, so that I could drop the direct mode support and switch to blitted mode, without killing all the performance.

  • I believe the blitted mode is fast enough for all CGA games, and removing the direct mode made the code smaller and simpler, and there is no danger of the game stopping because of an unsupported CGA graphics opcode any more.

    QJ.NET Ryan F. 2010

  • If I need to decrease the memory usage of DSx86 code at some point I might actually remove the CGA direct mode support, as I believe the games that use CGA mode will probably run fast enough also using the blitted mode, and keeping the direct mode creates quite a bit of code bloat.

    QJ.NET Ryan F. 2010

  • The advantage of this mode is that it is generally much faster than the blitted mode, as the pixels are written only once, and only the actually changed pixels are handled.

  • The biggest changes since 0.04 are the improved EGA support (so that Commander Keen 4 runs), and I also added the blitted screen update mode for CGA graphics mode.

    QJ.NET Ryan F. 2010

  • Some games (like Solar Winds) use the DS segment register to write to the graphics memory, so they will always need to use the blitted mode.

    QJ.NET Ryan F. 2010

  • Those modes also need a combination of direct and blitted mode, as they use the VGA registers and the full 256KB of VGA VRAM.

    QJ.NET Ryan F. 2010

  • In earlier version only the Direct mode was supported, now you can select whether you want to use blitted (60 FPS, 30 FPS or 15 FPS) or direct screen update.

    QJ.NET Ryan F. 2010

  • MCGA mode supports both direct and blitted mode, so you can try with the the direct mode first, and if you get unsupported opcode errors, fall back to the blitted mode.

    QJ.NET Ryan F. 2010

  • Speaking of screen update modes, I don't think I have properly described what the differences between those direct and blitted modes are, and how they relate to the different graphics modes that DSx86 supports, so I think it is time I do that.
