kc2img converts the following file types to raw KC tape images. Those
files contain the data bytes as written by the KC tape routines
with block number and checksum removed. So each block is saved
as 128 bytes.
Machine code files start with an 128 byte header (one block)
that contains filename, load start address, load end address
and optionally a start address whose presence is flagged by
a status byte. Basic files only have a 13 byte header with
filename and filesize.
1) files used by the KC emulator by Arne Fitzenreiter (usually
2) files used by the GEMINI-SOFT KC emulator (usually named .GPF
for machine code files and .GBF for basic files)
3) BASIC files (usually named .SSS)
4) KC image files that contain the data written by the KC tape routines
without block number and checksum (usually named .KCC or .KCB
where the .KCB files are BASIC files with an autostart routine)
