Menus are created in

ROM:FF305254 sub_FF305254                            ; CODE XREF: StartMenuMode+4�p

depending on the ModeZone (stored at offset 0x98 in struct at 0x14c48).

if ModeZone are 0-5, all Menu are created (A-Dep, M, Av, Tv, P)

ROM:FF305268                 BL      StartMnMainTabHeaderApp

if ModeZone are 9-15 and 19, (CA, Portrait, Landscape ...)

ROM:FF305280                 BL      StartMnMainTabHeaderImageZoneApp

If ModeZone is 20 (Movie)

ROM:FF3052A0                 BL      StartMnMainTabHeaderMovieZoneApp

Let's see extract of StartMnMainTabHeaderApp (0xFF3B15D8)

ROM:FF3B15FC                 BL      StartMnMainRec1App
ROM:FF3B1600                 BL      StartMnMainRec2App
ROM:FF3B1604                 BL      StartMnMainRecord3App

ROM:FF3B1618                 BL      StartMnMainSetup3App
ROM:FF3B161C                 BL      StartMnMainMyMenuApp
ROM:FF3B1620                 MOV     R3, #0
ROM:FF3B1624                 STR     R3, [SP,#0x10+var_10]

and StartMnMainTabHeaderImageZoneApp (FF3C8A90) :

ROM:FF3C8AB4                 BL      StartMnMainRec1App
ROM:FF3C8AB8                 BL      StartMnMainPlay1App
ROM:FF3C8ABC                 BL      StartMnMainPlay2App
ROM:FF3C8AC0                 BL      StartMnMainSetup1App
ROM:FF3C8AC4                 BL      StartMnMainSetup2App


A dialog box is created like this

ROM:FF3B1620                 MOV     R3, #0
ROM:FF3B1624                 STR     R3, [SP]                          ;level?
ROM:FF3B1628                 MOV     R3, #0x46 ; 'F'                   ;id (seems unique)
ROM:FF3B162C                 ADR     R2, MnMainTabHeaderApp_handler    ;handler
ROM:FF3B1630                 MOV     R1, #0                            ;arg2?
ROM:FF3B1634                 MOV     R0, #0                            ;arg1? 
ROM:FF3B1638                 BL      CreateDialogBox          // use 'fastcall' calling convention with IDA 'set function type'
                                                              // (Y key on function name) to assign correctly args to regs
ROM:FF3B163C                 TST     R0, #1                            ;dialog address
ROM:FF3B1640                 STR     R0, [R4]

the handler function is given in R2. R3 is supposed to be a unique identifier (to be checked)

and yes, Trammel already found this, see dialog_create() in dialog.h

Column1 is function number
Column2 is the MenuTab number (0 to 0xc)
Last column is the line inside the MenuTab (9 means first line)


Table for custom functions is simpler:

ROM:FF53D288 CFnMenuTable_TableNo DCD 0x35,0x40000   ; DATA XREF: sub_FF4044D4+48�o
ROM:FF53D288                                         ; GetMyMenuItemIdFromFuncNo+6C�o ...
ROM:FF53D288                 DCD 0x36,0x4000F
ROM:FF53D288                 DCD 0x37,0x4000E
ROM:FF53D288                 DCD 0x38,0x50000
ROM:FF53D288                 DCD 0x39,0x50001
ROM:FF53D288                 DCD 0x3A,0x50002
ROM:FF53D288                 DCD 0x3B,0x6000D
ROM:FF53D288                 DCD 0x3C,0x6000E
ROM:FF53D288                 DCD 0x3D,0x70010
ROM:FF53D288                 DCD 0x3E,0x70013
ROM:FF53D288                 DCD 0x3F,0x70011
ROM:FF53D288                 DCD 0x40,0x7000E

the FunctionNumber is used for SubMenu, like here for DustData Creation

ROM:FF3AE948                 MOV     R0, #0x18
ROM:FF3AE94C                 BL      MnStartApp_StartSubMenu

then

ROM:FF3A88F0 StartMnDustOffDataApp                   ; DATA XREF: MnStartApp_StartSubMenu+18C�o

...

ROM:FF3A8548 DlgMnDustOffData_handler


If someone knows how to link StringIDs and the offset to the related text in several language. For example, in ROM:FF3A8C08 DustOffData_wizard_maybe, it seems 0xd0, 0xd1, 0xd2 and 0xd3 are StringIDs for

ROM:FF6DFF75 aDustDeleteData DCB "Dust Delete Data",0
ROM:FF6E0230 aObtainDataForRemoving DCB "Obtain data for removing ",0
ROM:FF6E0581 aDustUsingSoftware_ DCB "dust using software.",0
ROM:FF6E0895 aReferToManualForDetails_ DCB "Refer to manual for details.",0

=> see some progress at GUI_StringIDs


Struct 0x14c48 stores a lot of settings like here at offset 0x174 for Histogram (type I believe):

ROM:FF202E64 set_histogram                           ; CODE XREF: SetHistogramToStorage:loc_FF3B22D4�j
ROM:FF202E64                 LDR     R1, =struct_14c48
ROM:FF202E68                 MOV     R2, #4
ROM:FF202E6C                 STR     R0, [R1,#0x174]
ROM:FF202E70                 LDR     R0, =0x2030005
ROM:FF202E74                 ADD     R1, R1, #0x174
ROM:FF202E78                 B       prop_request_change
ROM:FF202E78 ; END OF FUNCTION CHUNK FOR SetHistogramToStorage

the 0x02030005 property is also updated to propagate this change to tasks which are subscribers of this property.


another one (self explaining):

ROM:FF20C438 set_studiomode_maybe
ROM:FF20C438                 LDR     R1, =struct_14c48
ROM:FF20C43C                 MOV     R2, #4
ROM:FF20C440                 STR     R0, [R1,#0x244]
ROM:FF20C444                 LDR     R0, =0x8004001B
ROM:FF20C448                 ADD     R1, R1, #0x244
ROM:FF20C44C                 B       prop_request_change
ROM:FF20C44C ; End of function set_studiomode_maybe
