I tend to be again and again surprised about the interest in cc65 when
looking at
https://sourceforge.net/projects/cc65/files/cc65-snapshot-win32.zip/stats/timeline

Talking about DOS 3.3 there's still no support whatsoever in cc65 -
and I don't see it coming. But talking about ProODS 8 loading a HGR
file is as easy as:

int file = open("mypic.hgr", O_RDONLY);
read(file, (void*)0x2000, 0x2000);
close(file);

And loading a DHGR file means:

int file = open("mypic.dhgr", O_RDONLY);
read(file, (void*)0x2000, 0x2000);
// call into auxmove
read(file, (void*)0x2000, 0x2000);
close(file);

Do I miss the point or are you asking to have the code above
encapsulated?

Regards,
Oliver
