With this free HEX editor, HxD Editor, http://mh-nexus.de/en/hxd/
you can export the hex codes that appear in any LV6 game level,
and convert it into an HTML file which can be viewed in your
browser (such as in FireFox).
and voilà, the screenshot!
Why you'd want to do this, I don't know.

By the way,
the _TestLV6.LV6 has dimensions 90x6 .
sample files are enclosed.
