I tried to override the ISO to all kind of reasonable values, but the camera won't take the shot, and sometimes even crash.
I guess the props are changed, tomorrow I'll have to dump them in a file and see what happens.

Can someone with a DryOS camera tell me the value of their PROPCASE_TV under different light conditions, when the camera is in the P mode? Would make my works easier :/

Current status: I am working at saving the RAW file. I can't find mkdir(), spent a few hours trying to find it from the SX10 dump, but absolutely no luck, the firmware is very very different in this area, can't even find common strings.

I got the RAW to work with some hacks (although it crashes after taking more than 1 pic in RAW mode).
There is a lot of software correction of the images at wide angles..

WriteSDCard is probably FF933968, (leaving ReadSDCard as FF933780). This is based on FF86AF50, which also shows why udumper doesn't work, even with the right encoding. Interestingly, there are two more functions loaded into that structure (which I assume is some kind of driver) than in earlier cams, but they don't look like read/write.

PT_Playsound is probably FF87D8A8 (via the string, PT_Playsound)

UpdateMBROnFlash FF813F74 from
Code: [Select]
ROM:FF86AF14                 ADR     R1, aBootdisk   ; "BOOTDISK"
ROM:FF86AF18                 ADD     R0, R4, #0x40
ROM:FF86AF1C                 BL      sub_FF813F74

qsort FF9FC560, found by proximity to probable sscanf (FF9FC59C)

kbd_pwr_off and kbd_pwr_on probably don't exist, like sd990. Just nullsub them.

Mount_FileSystem Unmount_FileSystem, SetZoomActuatorSpeedPercent and rewinddir are all expected to be missing on dryos. Nullsub again.

apex2us you will find when doing exp_drv_task, if you choose to implement extra long exposures. Otherwise you don't need it.

Looks like SD980 should definitely be a new dryos reference firmware.

That's what I found:
strrchr ROM:FF813FE4
qsort   ROM:FF9FC560
WriteSDCard FF933968 (95%sure)
UnlockAF ROM:FF836928
DoAFLock ROM:FF8368F0
kbd_read_keys ok

qsort confirmed, I was actually just about to search for it for the file menu thingy.
