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!

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.
