yep -t cdrom did the trick, mscdex mounted it as cdrom
but level01.map was still missing. it is in folder LEVEL01 in the install dir.
i tested to copy all the files out of LEVEL01 to the Z root and voila, it works!! :))
only normal vga, with no sound atm, but i can play my good 'ol Z on my linux.
thank you, Qbix
are you afraid to die? it's being alive that frightens me...
