Sisopen

Sisopen - epoc and symbian file extraction utility Wednesday, 06 December 06

Sisopen is a tool to list and extract the content of SIS files. SIS files are installation files used in Symbian-based smartphones like many S60 Nokia phones.

Sisopen is an ANSI-C program, mainly targetted to Linux and other Unix-like systems it can be compiled almost in every system with a C compiler having zlib.

Defining NOZLIB at compile time makes you able to compile without zlib, but only file listing is available in this mode, files can't be extracted.

EXAMPLE

First example, list the content of a .sis file

$ sisopen sis/torch.sis

sis/torch.sis: SIS header detected
  application UID: 0x78F172C
  application version: 1.20

Languages
  UK English 

Files
000   !:\system\apps\Torch\Torch.aif                                        1941
001   !:\system\apps\Torch\Torch_caption.rsc                                  32
002   !:\system\apps\Torch\Torch.rsc                                          70
003   !:\system\apps\Torch\Torch.app                                        5548

A more interesting example showing the ability of sisopen to fully understand SIS files including conditionals:

$ sisopen sis/Nokia_N70_patch.SIS

sis/Nokia_N70_patch.SIS: SIS header detected
  application UID: 0x20000BB0
  application version: 1.00

Languages
  UK English 

Files
[endif]
001 f C:\DOCUME~1\m1smith\LOCALS~1\Temp\MKS0\WrongDevice0.txt                122
[else]
003 f C:\DOCUME~1\m1smith\LOCALS~1\Temp\MKS0\Finished0.txt                   254
004 c C:\system\temp\NokiaN70Patch1.exe                                     1552
005 f C:\DOCUME~1\m1smith\LOCALS~1\Temp\MKS0\Distribution0.txt               288
[if (0x10200f9a == MachineUID)]

SIS file conditionals must be read upside down, starting from the bottom of the output. This is a patch for the N70 smartphone so the conditional is if MachineUID == 0x... (the N70 UID) install the files, else show a Wrong Device message.

FEATURES

Sisopen is able to:

list SIS file content, including conditionals, file type, installation time options
extract files (try -x)
the verbose mode gives a lot more information about the sis header and individual files (try -v)
