Been trying all different versions of cr2hdr.exe and dcraw.exe, and everything I try comes back with the same messages:
QuoteT:\CR2HDR>cr2hdr DUAL0398.CR2
Input file : DUAL0398.CR2
Canon EOS M detected
Full size : 5280 x 3528
Active area : 5208 x 3476
White level : 12500
Black borders : 72 left, 52 top
Black level : 1987
ISO pattern : BdBd RGGB
Interlacing method not supported
ISO blending didn't work
Here's one of the many files I've tried, if someone could test it out and let me know if it works for them:

Running [EOSM]FullbackADTGui version of ML on firmware 2.02.
Hmm.. that is weird. I can get my EOS-M Dual ISO CR2s converted just fine. Try using the latest sept17 build of ML.
Hmmm, can't even get the Dual ISO module to work on that...
