Today I was playing with my SE a little.
From some time I tried to draw on player without a patch - but it seems to be impossible.

I found UltraShot's post on Se-Developers (I saw this post long time ago, today I remembered about that): http://se-developers.net/viewtopic.php?f=28&t=278#p2728
The most important thing here is a patch :-)

I started searching hook for this patch in C901 main:

Код:

(...)
ROM:14D27A00 08 49                       LDR     R1, ONREDRAW_METHOD
ROM:14D27A02 20 1C                       ADDS    R0, R4, #0

(...)
ROM:14D27A24 85 4E 49 14 ONREDRAW_METHOD DCD loc_14494E84+1
(...)

Entrypoint found :-P

Here's the patch:

I can draw on Walkman screen, but
- restoring old redraw doesn't seems to work - phone always reboots:
I tried like this:

Код:

DISP_OBJ_ONREDRAW_METHOD oldredraw=(DISP_OBJ_ONREDRAW_METHOD)(0x14494E84+1); //address for c901 r1ga028
void Redraw(DISP_OBJ *DO, int a, int b, int c)
{
oldredraw(DO,a,b,c);
};

Reboot. So I tried: if (oldredraw) oldredraw(DO,a,b,c); - the same result.

But it's not the most important problem. The most important problem...
How can I get path and name to file currently played by phone?
In db2020 it was easy,

Код:

typedef struct
{
  u16 unk;
  u16 unk2;
  wchar_t * path;
  wchar_t * name;
  wchar_t * MIME;
  int fulltime;
} BOOK_PLAYER_TRACK_DESC;


typedef struct
{
  char dummy[0x5C];
  wchar_t pos;
  char dummy1[0xE];
  int time;
  char dummy2[0x4];
  BOOK_PLAYER_TRACK_DESC * dsc;
  char dummy3[2];
  wchar_t pos2;
  wchar_t pos3;
  char dummy4[22];
  int tracks_count;
}BOOK_PLAYER_2020;

void somefn (){
BOOK_PLAYER_2020 *bkp=(BOOK_PLAYER_2020*)bk;
wchar_t *filename = bkp->dsc->name;
wchar_t *filepath = bkp->dsc->path;
}

And then we could get tags - now I can't, because structure of AudioPlayerBook in DB3210 is different. Don't care about MetaDataDesc_Create / Destroy / GetTags functions, it's not hard to get ID3 tags from file, even without function in library.

So... Anyone ? How to get name and path of file currently played by phone in DB3210?

I know about those functions, too :) But as I wrote before, tags are not problem, only path to file currently played by phone.

In short:
typedef struct
{
....
}BOOK_PLAYER_3210

:-D

How?

I tried:

Код:

void dump ()
{
  PROCESS pid = current_process ();
  char *ptr = (char*)malloc(4096000);
  memset(ptr,0,4096000);
  get_mem (pid,0x28000000,ptr,4096000);
  int f = _fopen (L"/card/other/",L"dump.bin",WA_Write | WA_Append | WA_Create,0x180,0);
  fwrite(f,ptr,4096000);
  mfree (ptr);
  fclose (f);
}

Don't matter what I write in second parameter of get_mem, file is always empty, and size is always 8000kb instead of 4096kb.

I also tried (OSADDRESS)(FindBook(isAudioPlayerBook())) as second parameter of get_mem, file empty.

ReaderRAM doesn't seem to work on my phone. I don't know how should I search that...

Держи, тока эльф без гет-мем) http://slil.ru/29473576

Joker XT пишет: Держи, тока эльф без гет-мем) http://slil.ru/29473576 Thanks, but everytime file size is 0 bytes. Edit: Anyway, dumping problem solved, I wrote my own [ Edited by mc_kibel в 17.7.10 17:35 ] Added 17.7.10 18:42 I found what I need once path: 0x4BBACC5A name: 0x4BBACE52 but it's in ram, it's different everytime. I have no idea how dump can help me.

SOLVED

I wouldn't do it without mcming1989 - he explained to me, how to read informations from dumps - big thanks to him!
:-)

Код:

typedef struct
{
  wchar_t *fname;
  wchar_t *fpath;
  char *MIME;
  wchar_t *extension;
}BOOK_PLAYER_TRACK_DESC_3210;

typedef struct
{
  int unk;
  BOOK_PLAYER_TRACK_DESC_3210 *xdesc;
}DESC_PTR;

typedef struct
{
  char dummy1[0x4C];
  int time
  int unk_1;
  DESC_PTR *dsc;
  int unk_2;
}BOOK_PLAYER_3210;

void somefn ()
{
    BOOK_PLAYER_3210 *player = (BOOK_PLAYER_3210*)FindBook(isAudioPlayerBook());
    debug_printf ("\n -->> Current path: %ls ; name: %ls ; time: %d \n",
                player->dsc->xdesc->fpath,
                player->dsc->xdesc->fname,
                player->time);
};

Functions in LibraryDLL for getting mp3 tags are so slow :( Animation is about 5-7 fps...
