VS23S010 Palette Editor (microcode simulator)

[Panu]

Dear VS23S010 users,

At viewtopic.php?f=14&t=1813&p=8938#p8938 you can find a tool for exploring the VS23S010 PAL/NTSC colorspace and palette (microcode) options.

For those of you running Linux, Panu's Windows binary has been tested to work on Kubuntu 14.04 LTS under Wine, although it runs significantly slower than on native Windows.

If you are running some flavour of Unix and want to try, I've attached a command line version of the program to this message, along with some library code I wrote decades ago that makes it possible to write the palette as a NetPbm .PPM image file.

The source code is very small, and included is a simple Unix Makefile, so you should be able to compile it in less than a second using your favourite Unix flavour by just saying "make" in the project directory.

Example run:

Code: Select all

vs23s010_microcode> ./vs23s010microcode -p -o out.ppm N:C4:B62:A63:Y33:N10
FYI: Colour burst amplitude 5.7, phase 135.0 degrees
FYI: Microcode uses 8 bits per pixel, colourmap has 256 colours
FYI: Success
