Jean-Claude,

thanks for the hint with "ozf2img" - I will take a look at it.
>From what I heard the file is something like a lightweight tiff, will
say it is organized in tiles (each 64x64 pixels). Each pixel has the
size of one byte and stores an index of a color palette. This is at
least the basis - then there come some overviews more into play which I
do not as much up to now - but I want to dig my way into it.
