Yes exactly.

reconstructed sources. Is the source of that stuff unavailable ?

Of course it is, otherwise it won't compile to an identical image ;)

The show_file() command is handled in https://github.com/th-otto/tos1x/blob/
master/desk/deskshow.c, and the format dialog in https://github.com/th-otto/
tos1x/blob/master/desk/deskdisk.c. However, the versions in tos 1.00 seem to 
be quite different, that's why i left them out for now (only assigned some 
dummy labels corresponding to the LineF opcodes). Remember also the separate 
resource file for the format dialog. Looks like they tried to mimic the 
behaviour of the x86 version, which does some strange things to load 
FORMAT.COM and run that as a separate process.

BTW, could be that one of the additional data blocks in the builtin resource 
data contains the desktop icons. Atleast they are not in the normal resource 
file. But i have to check that, the offsets from the glue header look a bit 
strange to me, especially in the german version.
