Ok, I fixed it by allocating only 256kb in exmem and not loading chdk in exmem. 256Kb is still enough to prevent the crashes when switching to play mode. Quality overrides work now.

Ok, here's a new build.

Fixed:
-ISO overrides (it's setting the real ISO so the numbers are a little different in exif)
-ISO bracketing
-AV bracketing (uses new function MoveIrisWithAV() like g12)
-bracketing in custom timer mode
-crash using manual focus (now fast_zoom is disabled in ALT mode). Calculation error of feather bits.
-the menu started to show small icons

Know issues:
-AV overrides not working anymore
-Edge overlay and zebra are shifted and distorted on Y axis.
-AF scan sometimes still crashes only when in manual focus mode

Needs more testing.

thanks Funnel, i am testing hard the new beta
i don't understand why sometime the bad pixel remover doesn't work (raw and jpg) when i use long exposure
also i don't understand why in the raw pictures there are some green and purlple bad pixels altought the bad pixel remover worked.
i used the option "Raw" remover option, and i created the badpixel file with the lens covered.

Badpixel and Dark frame substraction are two different thigs. For long exposures you must turn on dark frame substraction. DFS takes place automatically in the original firmware when exposures are longer than 1.3 seconds, you see this when the "Busy" appears after the shoot.

thanks, i turned the DFS to "on" (it was auto) and now works, no more green pixels in raw shots.

i also noticed that if i set iso800 the picture is shot at iso800 even with overrides enbaled at lower iso (iso60)

After following this thread since page one or two ;-) I finally bought the camera (Firmware 101A) and installed CHDK today.

Great work, funnel, thank you loads for all the efforts you put into this port! Testing of the beta1.1 (will update tomorrow) I have a problem with the menu always being "washed away" by all-too active screen activity of the cam. Is there a way to put chdk "always on top"? This maybe a noob question, I'm sorry... This said, chdk is usable, of course, you can just move up&down in the menu to let it be displayed again long enough to know where you're at.

This is unfortunately normal for CHDK in general.

Don't forget what the H stands for.

Found a bug, ISO override works only in AUTOISO mode. When in manual iso mode and shutter half pressed I see that the PROPCASE_ISO_MODE gets set to 0 but looks like this doesn't change the iso to auto mode.

@onesky
ISO is getting set ok, you probably forgot to input the factor value.
