@alex: Thanks for the quick reply. I'll have a go and let you know if I struggle

Hi,

How do you run the EOS M6 into qemu ?  There is already a structure for the M5 therefore I've tried the CHDK dump from https://drive.google.com/open?id=0B08pqRtyrObjWVdWVGVwakVmcjQ#list  but there is only a PRIMARY.bin file; how do split it to have the expected ROM0.bin and ROM1.bin ?

Before going any further, can I use qemu to use the default Canon's basic scripting, instead of constantly moving the SD card in/out of the camera/laptop ?  I'm not going to emulate ML or CHDK.

So far I've installed qemu from the ML qemu branch (followed the README from the contrib folder) which is version 2.5.0. Is this version not too old?  ...there is a qemu-2.9.0 branch but it's not maintained since April last year.


Cheers,

sent a PM for both firmwares... will see if I can do something (I can program in Java and C)

I couldn't get the "hello world" script working but the dumper script has produced a ~33M file!  How do I check if it's valid?

...not an exceptional firmware update but we have a now an official firmware for porting the M3

Here's the source, but building it requires some serious patching of ML DNG code (to add floating point support).

CeroNoice.c

From what I remember, you need to upgrade to DNG 1.4, remove the bad pixel opcodes, and tag the file as floating point. Building it with 16-bit integer output should be easier, but the dynamic range is very limited (only useful for those cases where dual iso is enough).

...do I need some serious patches to enable 32bits? 

@a1ex: do you have the link for the latest source code and all the patches required so I can compile it for Linux (Fefora) ?  ...is your ufraw patch against the latest version?
...do you have a make file or something similar?

...ok fine but how do you achieve the calculation of the "best guest" of the midtone/highlight/shadow ?  ...maybe by doing a histogram redistribution/equalisation and comparing with the original?  (don't know I'm just speculating or talking rubbish!!)

Otherwise did you see my PM? 

...is there a way of generating roughly the correct amount of midtone/highlight/shadow levels needed for a specific image?  ...maybe based on the histogram?  ...or is it just based on try and error to get a pleasant result?
