PSGroove Modified for PS3 Backups Without a Disc in the Drive!

Sponsored Links
227w ago - Today Spanish PS3 developer Hermes at Elotrolado.net (linked above) has shared a modified payload version of PSGroove, which allows users to run PS3 backups without requiring a disc in the PlayStation 3 drive.

To quote, roughly translated: Taking advantage that I have my AT90USBKEY, I used the disassembly of the payload (made by me), the descriptions in ps3wiki.lan.st and part of AerialX source, with the following objective:

1) Have a damn once the source of the exploit, with amendments, etc, enough is enough for us to pass an array and pulling miles.

2) I used to make some changes, with a very interesting result.

The first thing to tell, is that the payload is loaded into a memory area (700 000) and ends up turning part of your code into an area that is too full. Just add four things we can and in fact, for my change I had to relocate a table with patches (do not think you are having problems in the position you are).

The second is that I managed to enable loading of backups with the amendment introduced AerialX by his side, in order to launch applications from a flash drive (HDD) attached on / dev_usb000 (of the four ports, which is more to the right, in my case). My directly AerialX code did not work and removed much of what makes this load backups.

The fact is that you can put in root folder PS3_GAME with the appropriate structure (see the readme.txt of the package) to launch a EBOOT.BIN selecting the menu "/ app_home/PS3_GAME"

But it is not here: thinking that this could throw the EBOOT.BIN of a game, I thought about making a communication, so that by granting syscall36 (or directly, as I saw it), could "see" the game to launch in "/ apps_home/PS3_GAME" when no disc.

Surprisingly, it works. I do not know if there are games that are problems or not, but I've tried, they all without having to have the disc.

The problem is that the original manager asks you to drive before launching game balls, but the manager does not have to do anything that can run games, except set the path of the game by syscall 36.

In doing so, memory is allocated to a pointer, which is what I use to switch between "/ apps_home/PS3_GAME" to launch an application without installing the console (same in development) or redirect the game to run.

This is a string of code development and here I'll upload the full psgroove with lufalib and my modifications, the source of the payload is ready to compile. If you are a using a PIC, you just have to change the payload (replacing the array of payload. H that is generated when compiling and also provide) and have no space problems, or anything else, because it takes what same

Short Summary

If you have not understood a word, this is a thread of development which is offered as a heading, the code that makes the "magic" disassembled and modified to provide a way to run homebrew without installing the console and on the other hand, load your backups using that trick, they do not need a disc in (the bad is that it requires a new manager or patch the old hard not to ask to leave).

Quick Hack for Backup Manager by me:

- NO BDVD Check
- NO Jump Back to XMB

It starts the game directly from Backup Manager.

Known Problems:

Games like Wipeout still needs to pre-install game-content first or they won't run.

The new backup manager does not read the internal drive? or did i miss something here? Also Final Fantasy will freeze when you try to load it.. it will goto the square enix screen and then freeze.

Does any one know if F1 2010 works with this? (without the "controller disconnect issue)

is there anyway to have the new backup manager and the old on the same xbm menu ? as the new one over writes the old version.

Thanks for the Teensy 2.0 hex. Correct me if I'm wrong, this method only works with external usb drives and only supports one game at a time for the moment? Also, it will require a new backup manager.
