I downloaded an CR3 image with name 023A9867.CR3 from
but using the latest snatshop 202101 I cannot generate a *.tiff image.
Using dcraw_emu.exe I get: Cannot open 023A9867.CR3: Unsupported file format or not RAW file
The problem seems to be with file_open.
It is not clear to me, what I am doing wrong.
The snapshot release documentation tells that Canon EOS-R5 camera is supported now.
Any help appreciated
Thanks in advance
