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


Sponsored Links
232w 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.

Download: PSGroove Hermes Payload Modification

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).

so I played around a little bit more and the hermes manager I posted earlier works this way:

Load Backup Manager
Select backed up game
It will then exit to XMB
Select app_home/PS3_GAME
Game will start

A lot of game don't work as of yet so we will need to post what does and doesn't work, but save that for another thread.

Nice one LioMajor, but i still get the port1_config_descriptor.S error. The system cannot find the file specified.

Did you manage this using WinAVR and do you have the ppu-gcc directory its looking for?

This is greast news, things are progressing so quickly! I hear the banning of PSN due to backup manager was all lies is this true? even if it was the case this patch seems like it would be harder to detect games played from backup media now and maybe online play could be an option?

Also could you not have all your games on 1 external harddrive still and just rename the folder to the one you would like to play? Just a thought or two

Regards

Liomajor:

your manager does not work for pretty much every game, well every game I have tried. I am also loading from an external HDD

For windows i fixed the problem taking out any comments in port1_config_descriptor.S and it compiled well.

Any chance you could upload your port1_config_descriptor.S?

Thanks
