PS Vita - Virtual Game Card (psvgamesd) is an user application and kernel plugin that allow to produce game card dumps and run them.

This application is designed for two main tasks:

Produce 1 to 1 dumps of game cards.
Introduce functionality that allows to run these dumps.

Application consists of user application that manages the driver settings and kernel plugin that is used to emulate game card.

Installation

Before installing

Requirements:

HENkaku
taiHEN

Compatibility with sd2vita adapter:

This plugin is not compatible with sd2vita adapter and corresponding gamesd.skprx plugin.
This plugin is not compatible with any other kernel plugin that is derived from gamesd.skprx.
If you are going to use this plugin - disable gamesd.skprx.
Ideally it is recommended to remove sd2vita adapter. However when inserted - it should be ignored by this plugin.

Compatibility with game cards that have grw0: partition:

There are some game cards that have write partition. It allows to write on game card.
Currently such game cards are not supported. This is planned for next release.
If you want to help me with this issue, please drop a comment at #10.

How to install

Install kernel plugin:

Copy psvgamesd.skprx to the location where you have kernel plugins.
Add the path to config.txt.
Reboot your vita.

Install user app:

Install psvgc.vpk.
Virtual GC bubble will appear.

User guide

User interface

Upon launching user app you will be presented with console UI:

Current mode is indicated on line "driver mode:".

Physical MMC mode (produce game card dumps):

Insertion status is shown on line "content id:".
Dump progress is shown on line "dump progress:".
Dump file is stored at ux0:iso folder.

Virtual MMC mode/SD mode (running game card dump):

Selection status is shown on line "selected iso:".
Insertion status (insert/remove) is shown on line "insertion state:".

Use cases

Typical Emulation use case:

Use physical mmc mode to produce 1:1 dump of the game card.
Use virtual mmc or virtual sd mode to run the game.

Typical Physical Storage use case:

Use physical mmc mode to produce 1:1 dump of the game card.
Use your favorite tool or hex editor to burn this dump to SD card.
Use physical sd mode to run the game.

Huge dump size, trimming, compression etc

Trimming zeroes:

Initial design of the format assumes that 1 to 1 dumps are produced. However you have a total freedom to derive a trimmed version of the dump from the original file. Ideal solution is to create a tool that does the trimming.

Solution for experienced users is to remove zeroes in the end of the file using hex editor. However you have to make sure that you are only deleting zeroes. You also have to keep in mind that data is 512 byte aligned. After trimming - you can set corresponding FLAG_TRIMMED flag in the header of the file.

Compression:

At this point in time compression does not make much sense since data in the dump is encrypted.

CMD56 handshake

Data from the handshake is required to pass signature checks and obtain klicensee. It is integrated into dump file.

When game card is inserted in physical mmc mode signature and keys are intercepted and saved to dump file later.

Dumper comparison

Dumper comparison by Yifan.

Key points:

Stop using Vitamin/MaiDumpTool. Those tools were hacked together before taiHEN was ready and therefore depends on hacks around the fact that there was no kernel access. Game executable metadata was not preserved and creates lots of compatibility issues including corrupting saves while in suspend mode.
psvgamesd creates .psv files which will be the standard archival format for Vita games (like .iso or .nds but for Vita). These files are not trimmed or compressed and therefore will take a lot of storage to save. Until trimming/compression features are implemented, a way to use the best of both psvgamesd and NoNpDrm is to save your raw dumps on your computer (for backup) and when needed (like if you lose access to your cart), you can use psvgamesd to mount the image once, then use NoNpDrm to "install" it as a bubble (saving space) and finally delete the original .psv from your Vita.
psvgamesd allows you to backup your 3.61+ games for use if/once later firmware are hacked.
psvgamesd currently does not support backing up digital games but the .psv format will eventually be used to archive digital games as well. More information on the format is here.
When a .psv is mounted with psvgamesd, you can run any other tool (including NoNpDrm and Vitamin) on it, so until existing workflow (such as game translation) is upgraded to not depend on legacy dumps, it is always possible to go from .psv to any other format but not the other way around. You must dump the original cart to create a .psv.

Author's Legal Disclaimer: I helped author the .psv format to help standardize the format for backup and archival but I do not endorse any method to circumvent DRM. This guide is provided for informative purposes only and does not serve to aid any party in circumventing DRM. I have not worked directly or indirectly on any DRM circumvention features.

+'''Compression:'''
-=== Trimming zeroes ===
-I see quite a lot of complaints about size of the .psv files. I guess I should have explained it from the start. Initial design of the format assumes that 1 to 1 dumps are produced. However you have a total freedom to derive a trimmed version of the dump from the original file. Ideal solution is to create a tool that does the trimming.

+===CMD56 handshake===
-=== Custom board ===
+Data from the handshake is required to pass signature checks and obtain klicensee. It is integrated into dump file.
-Use custom board. You can check how it can be built here: https://github.com/motoharu-gosuto/psvcd
-There are two modes that can be used there.
-* Use PS Vita as black box (cmd56 handshake is done by PS Vita)
-* Use PS Vita F00D as black box (cmd56 handshake is done by board)
-For second approach you will need kirk plugins that are located here https://github.com/motoharu-gosuto/psvkirk
-Code for second approach is not finished. It only does cmd56 handshake. However you can use the code from first approach to dump the card. Only little changes are required.
-=== PSVEMMC client ===
-https://github.com/motoharu-gosuto/psvemmc
-Unfortunately dumping client is not finished. It is only capable of doing a dump per partition. It does not dump SCEI MBR and does not combine partition dumps into single binary file. However only little changes are required to make it dump SCEI MBR. You can then combine dumps with your favorite hex editor.

-Some are trying to relate to so called &quot;leak&quot; that was recently published here: http://wololo.net/2017/09/13/vita-reverse-engineering-leak-cobra-blackfin-part-1/ I can claim that there is nothing new for me in that &quot;leak&quot;. My research was always open to the public and is completely independent from Cobra Blackfin. During the developement I have stated and explained this many times. You can also check it here in my first publication that happened year ago: https://github.com/motoharu-gosuto/psvcd. Please read closely the Introduction.

+Select - Remove game card
-Others are trying to relate to the .psv format of Cobra Blackfin. I can claim that the format that we have develped with Yifan and devnoname120 is a completely independent format and has nothing to do with Cobra Blackfin. I hope you can make the differences by reading this: https://github.com/motoharu-gosuto/psvgamesd/blob/master/driver/psv_types.h As well as checking this developement thread: https://gist.github.com/yifanlu/d546e687f751f951b1109ffc8dd8d903
