Metal Edition (Version 22.5.2017, Fourth release)

With Multipaint, you can draw pictures with the color limitations of some typical 8-bit computer platforms. The screen formats supported are Commodore 64 high resolution, Commodore 64 multicolor, Commodore Plus/4 Hires, Commodore Plus/4 multicolor, ZX Spectrum, MSX 1 and Amstrad CPC0.

As Multipaint is written in Processing, it should run in Windows, Mac OS X and Linux 32/64 bit systems. For running the application, you need the Java Runtime Environment. Especially on Mac OS X, the chosen Java version may affect screen refresh speed. Processing binaries cannot be guaranteed to work correctly across all operating system versions. In that case it might be helpful to install Processing and run the sketch instead.

NOTE to Mac users (3rd of June, 2017): If Multipaint loads, but the icons don't show properly, try this one weird trick: Copy the icons.bin file from the application folder to your system home folder. Then run Multipaint from the application folder as before.

19th of May, 2018: I received another tip for the Mac problem which may be more useful: remove the quarantine extended attributes from the files, i.e.:

xattr -d *

NOTE to Processing 3 users: The current sketch source does not compile on Processing 3, so for now use Processing 2 instead. I did try to make the source work on both versions but with the latest additions this seems to be impossible.

If you have chosen to run Multipaint as a sketch, place the multipaint folder to your Processing sketchbook folder. Run Processing, load and run the sketch, select the machine of your preference and go.


Latest version

The Metal Edition (version 22.5.2017) is the fourth release of Multipaint. This version introduces a new paint color behavior model. Other changes are preset dithers with related tools, improvements to mouse events, a new color indicator and a more consistent behavior across platform and a general tidying up of functions.

A bug was fixed that prevented the machine selection working from the preferences file. A more complete list of new features is included in the manual.
