Hi pixdeldoc,
Have loaded CHDK and run up - thank you for getting us this far ! My findings so far :
1 - Can bring up the menu and navigate the menu tree correctly.
2 - On exit from the CHDK menu the screen freezes,for example if I am in Display, I can however then switch to Play via pressing the shutter release and screen repaints and all controls working correctly - in programme Av for example I can control aperture, flash and compensation as normal. However no changes to Canons OSD (no battery charge indicator, grids, histogram as set in CHDK menu etc).
3 - It takes pictures correctly (however the values set in CHDK are not applied).
4 - While in Record I can switch back to CHDK menu and back to the Canon OSD - though as above it is frozen. If I switch to Play and then shutter release again to go back to Record it repaints and works fine. I can cycle through this as many times as I wish and I had no problems. CHDK Menu is always running in the background and can call up when required via ALT keys.
5 - I was able to change fonts \ sizes and colors to the menu text and background colors - this works fine and is retained.
6 - Set User Menu to root - this is retained and when ever ALT keys applied this shown first and I can navigate then to the main menu.
7 - I tried changing the time display via the CHDK Menu from 24hr to 12 hr - on exiting CHDK menu there was no change to displayed or logged time.
Is this what you were expecting ? I am not sure what other functionality you have been able to enable - I haven't been able to see any actual change in pictures, jpeg or RAW (as set up in CHDK).
Let me know if you need anything specific looked at - looking forward to the next release
