= Game Packages =
All game packages are signed with the ECDSA signature. The public key for it can be found in '''download_plugin.prx''' or in '''nas_plugin.prx''' (this also applies to NPDRM SELFs). Usually game packages are signed with two signatures - one for the header and the other for the entry table.

== File Footer ==

=== PackageDigest ===

This is SHA1 digest of package without last 32 bytes.

The last 0x20 bytes of the package contains a hash (sha1sum) of the package (sha1 of the whole file minus the last 0x20 bytes). Or in other words... to verify the integrity of a package is needed to crop the 0x20 bytes at the end, then calculate the SHA1 of the resulting file, then compare with the SHA1 that was cropped.

It is also used as part of the package identification info inside the '''TITLE_ID-ver.xml''' files in PSN servers that lists the available game patches for each game. See: [[Online_Connections#Game_Updating_Procedure|Game Updating Procedure]] page and the '''sha1sum''' in the .xml examples

*Notes
**This footer area is considered part of the package and is included when counting the '''total_size''' of the package (in the header at offset 0x18), and the header is hashed too by '''header_sha1_hash ''' (at offset 0xB8), this is important in the sequence of actions needed when building the package and updating/adding the sha1 footer at the end
**Homebrew packages (at least some of them) doesnt includes this footer

Game Manual Protection
To use NPDRM to protect the game manual, include the line "ProtectDocument = TRUE" in
the configuration file. Like the downloadable game itself, once protected, the relevant game
manual can only be browsed on a PSP™ that was authenticated with the user account used
to purchase the downloadable game package. If "ProtectDocument = FALSE" is specified or
if no specification is made, the game manual will not be protected by NPDRM.

Startup Warning
You can specify that a startup warning be displayed when the game is started up. Specify
"HealthWarning = " followed by the specification word shown in the following table, which
indicates the region or language where the downloadable game package will be released.
See Chapter 7 for the corresponding text that is displayed.
If "HealthWarning = NONE" is specified or if no specification is made, no startup warning
will be displayed.

|-
| ZIPThreshold || used in PSP Downloadable Game Package (PSP .pkg)
Compression Rate Specification
During authoring of a downloadable game package, the data in the associated UMD™
image file is compressed. You can change the compression rate by specifying
"ZIPThreshold=" followed by the compression rate (0 to 100). If there is no "ZIPThreshold="
specification, the compression rate will default to 80. If "ZIPThreshold=0" is specified, the
data will not be compressed and there will no longer be any load for expanding the
compressed data. However, the file size will increase and it will take longer for the user to
download the package. Unless you specifically need to change the compression rate, do not
include this specification.
|| 0 to 100 || 80
|-
| OptimizeLevel || used in PSP Downloadable Game Package (PSP .pkg)
The SCE authoring service may change the optimization level to improve processing
performance when the system reads data in a downloadable game. If this change hinders
the behavior of a program that is being developed, you can include the specification
"OptimizeLevel=" followed by the optimization level that was used previously during
authoring. If there is no impediment to program behavior, you should not enter this
specification.
When the authoring service changes, refer to details that are publically available in the
Technical Notes.

|-
| BootablePlatform || used in PSP minis Package (PSP minis .pkg)
When creating a package for minis, in addition to the necessary parameters for downloadable

for packaging.
|| minis || minis
|-
| BootablePlatformDetails || used in PSP minis Package (PSP minis .pkg)
Game applications created via the Simple Authoring Service(SAS) having the above parameter
specified can be executed on PlayStation®3. When it is required to prohibit a minis game
application from running on the PlayStation®3 execution environment explicitly, set
"BootablePlatformDetails=onlyPSP" to NPDRM.CONF in addition to the setting
"BootablePlatform = minis".

==== Make Edata/Package NPDRM GUI by SubZero Dezigns (2012) ====

==== Force Package NPDRM by DEL1GHT Team (2010) ====

FORCE_PACKAGE_NPDRM is a modded version of SONY's "MAKE_PACKAGE_NPDRM".

It enables the repackaging of DRM'ed games into a .PKG file.

Howto :

First create the following structure :

	* PARAM.SFO

	* ICON0.PNG

	* ...

	* TROPDIR

	* USRDIR

		* Original EBOOT.BIN renamed to whatever you want (ie. GAME.BIN)

		* YOUR EBOOT.BIN (SELF file)

		* ...
	
Your EBOOT.BIN must launch the original EBOOT.BIN (ie. GAME.BIN)
	
Usage : force_package_npdrm [options] config-file target-directory

	11/08/10 - V1.00 - Initial Release

		- Based on SONY's "MAKE_PACKAGE_NPDRM Rev. 1203"

		- "Extended" help with "--help" option

		- Packaging of your SELF EBOOT.BIN

		- Repackaging of SELF/SPRX/EDATA DRM'ed files 
		
	11/11/10 - V1.50 - Updates

		- Based on SONY's "MAKE_PACKAGE_NPDRM Rev. 1732"

		- Repackaging of SDATA DRM'ed files

		- Repackaging of TROPHY directory

==== PSN Package NPDRM by DEL1GHT Team (2010) ====

PSN_PACKAGE_NPDRM is a fork of FORCE_PACKAGE_NPDRM.

It rebuilds PSN DRM'ed games into a .PKG file.

Original DRM'ed EBOOT.BIN is packaged as "raw data" ;-)

Still the problem of licence (act.dat) to run the game on another PS3.
	
Howto :

Download the PSN game directory from your HDD0 to your PC.

Create a "config-file" (a lot of explanations on internet).
	
Usage : psn_package_npdrm [options] config-file target-directory

	11/11/10 - V1.00 - Initial Release

		- Based (fork) on FORCE_PACKAGE_NPDRM V1.50

		- Full repackaging of PSN games
