The rules link from main page works for me: http://chdk.setepontos.com/index.php/topic,2.0.html.
That said, welcome and good luck with your port.  :D

Ok, I finished porting CHDK everything seems to be working

There is little bug: RAW files always will be saved in directory 100CANON and names will be CRW_[random nuber].CRW
This is because i had some problems with getting current file number using GetParameterData. (address seems to be correct so maybe this firmware have changed GetParameterData procedure)

I attach source and compiled bin.

Maybe in shooting.c
#define PARAM_FILE_COUNTER  0x34
is incorrect.

For cameras with the same age (~PID) this number is 0x2F, 0x2E (dump required to find it exactly)... You can find it using ParameterDara browser in debug menu (number is incremented by 16 after each shot).
