MSX Screen Conversor 0.8 Standalone

After many difficulties and general lack of time, I managed to release the standalone version of MSX Screen Conversor.

Grab it while still hot!
http://code.google.com/p/msx-screen-conversor/

It's not as polished as I'd like it to be, but it should prove useful enough.

And remember: there's no better way of keeping MSX alive than sharing code and knowledge. So please send patches, help your fellow MSXzer :)

Update: Win32 binary now available!

  • Hello.
    I'm MSX coder specialized in coding with SDCC. My name is Alberto (nick as Nerlaska).
    I'm very impressed with you MSX Screen Conversor routine for Screen 2. I would like to know what kind of Dither Algorithm you have used. I would like to adapt your algorithm in some PC Tools for MSX. Can i take a look to your code? Thank you. Regards! and MSX Power!! Alberto(Nerlaska)

  • Hi Nerlaska.

    The dithering algorithm is very simple and it works exactly as described in here.

    The Screen 2 color conversion (quantization) is somewhat confusing in its form, but the concept is easy to grasp (basically a brute-force search function minimizing the error).

    Everyone can take look at the code, since it's released with a GPL license. Just follow the first Google link in the post and you're set :)

    Bear in mind that if you actually reuse the code verbatim, your code should also abide to the GPL license.

    Cheers,
