Hello,
I also have a G9 (rev 1.00i firmware) and CHDK build 0.9.6, revision 714. MDFB-080914 works great for me.
Attached photo was taken with an external Nissin Di622 flash set to manual power mode, G9 in manual mode, 1/250 sec, f2.8. With the camera in any mode other than M, a pre-flash will be fired before the main flash and actual exposure. This is what slows you down when in flash mode.
Am having loads of fun with the CHDK hack, especially after being frustrated for a while for having upgraded my firmware to rev i and a day after finding out that a G9 hack was already available but not for rev i.
I have made a USB remote from an old car alarm keyfob. I'll share photos of it shortly, and also my external G9 battery made from laptop lithium ion cells.
Thanks to everyone who has contributed to CHDK. This is a great community.
