These are files created when you save a C64 window under PC64 (DOS only).
It consists of a 64k memory dump, color ram dump, I/O ports, the name of
the ROMs you were using at the time, and user-setable options. Typical size
is around 69091 bytes.

Byte: $00000-00008: The signature "C64Image" followed by a $00. Note the
varying case of the text.
00009-10008: Main memory of the C64 (64K, $0000-FFFF)
10009-10408: Color memory (1k, $D800-DBFF)
10409-?????: I/O memory and user-selectable options (ROM version,
etc). The ????? means the end of the file is not
known, since these files can vary in length.
Since these files are only supported by PC64 for DOS (*NOT* for Win95),
it is not worth getting too much into the layout. I was attempting to
decipher the layout of the I/O ports and options area but decided it wasn't
worth it.
