Hi guys, I am a total nube but I was wondering is it possible to install any version other than 1.03 for my Canon SX10is. Could I maybe upgrade to stable 1.3?
It sounds like you might be mixing up CHDK versions and Canon firmware versions. The current stable CHDK is 1.3, and AFAIK we never released a build called 1.03. If you install CHDK following the instructions on the wiki, you'll get 1.3.
You cannot update the canon firmware unless canon releases an update.
If not could you share some guide how to make capturing of raw files faster. Thanks in advance!
Aside from getting a faster SD card, there isn't really anything to change. If you are actually using a really old version of CHDK (before 1.2) then upgrading will give you somewhat faster DNG saving.
