Is there any info available on the structure of the Dynamic Publisher file formats (.PCT and .STP), and how they can be read?

.STP files seem to be standard MSX-BASIC COPY files for screen-6, but I'm not sure if what's the expected palette and if they can contain 4 colors or only 2 colors.

This comes directly out of my 20+ year old memories with no any kind of guarantee, but I have a feeling that *.PCT was 512 pixel wide picture with some sort of (not very complex) RLE encoding and it had custom height that was defined in header... or then it was something completely different... (sorry)

Hans Otten wrote a pascal program to convert PCT to PCX: http://msx.hansotten.com/software/pascal-and-msx/

Check the CNVS version 2.3 download and look for SPCT.PAS to decode the PCT files.
