I just checked the retail Polish version (not via ScummVM) and the map is present, but still crashes in ScummVM.

Confirmed for polish version. The other versions work just fine.

Pushed a partial fix for this as commit 3853bcf2628912e98681fda26d121c2b1f161c7a.

The relevant image is uncompressed i.e. no LZSS compression which is indicated by an
uncompressed size field of 0. This was not being handled correctly hence why this failed.

However, there is still a further problem here as the colors for the map are inverted with a white edging (not black as expected) and purple island (not green). There is no
color palette and the image is 24bpp, so not sure why that is happening, but no crash at least.

I can confirm that fix works also with the retail Polish version.
Checked in the latest daily build.

comment:9 by digitall, 3 years ago

iGom: To be clear, are the colors of the map correct for the retail Polish version?

comment:10 by iGom, 3 years ago

Oh, sorry for didn't mention that, no, colors are still inverted.
