A couple of more codes tried:
00001003 00000000 PressPBButton <--- another way to switch cam from REC to PLAY
00001001 00000000 PressRecButton <--- another way to switch cam from PLAY to REC

So, even though the A570 does not have a playback button (it has a slide switch) this works.
I cannot get it to work on the ixus75 that does have a playback button.
I will check again tomorrow.

What is an 'enjoy'  button ?

Strange, that does blank the screen on my A620.

0000105e 00000002 ModeDialToC <--- a570 has no C mode... but this does make the cam go to a user settings mode, sort of. Problem is, if I try to go to Canon's func/set menu to change ISO, camera shuts down with lens out. It does let me change WB settings and browse the func/set menu. Also the large mode indicator letter in Canon's osd is a blank dark area, not C as one would expect. So C mode is partially implemented but not enough to use it.

Very similar to a710 (when camera shutdown at assert() is supressed). All controls are the same in "M" mode.

About third value in data array: some ( but not all) rules:

if "press_something"  -  0
if "unpress_something"  -  1
if "rotate_something"  -  2
if "hold_something"  -  3

0x607C+0x4C for SX100

Where does the 0x4C come from ?

Have not tried any cameras with playback pushbuttons yet.

No, I returned SX100 to its owner.

Just from comparing '_DecideModeDial' subroutines from a710 (sub_FFD9CE8C) and sx100 (sub_FFC6593C for 1.00C).
But sx100 may not require a change in this variable (like a570).

Sure, I found that  :-

ADR     R1, a_decidemodedia ; "_DecideModeDial"
MOV     R0, #0x20
BL      sub_FFC59F58
LDR     R5, =0x607C
MOV     R4, #0
STR     R4, [R5,#0xC]
LDR     R0, [R5,#0x1C]
CMP     R0, #0
LDMNEFD SP!, {R4-R8,PC}
BL      sub_FFD3AF44

There is the 0x607C, where is the 0x4C offset ?

Hmmm .. that would mean testing a lot of cameras.

Asking users about something - a nightmare for the developer  :).
