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

Sponsored Links
231w 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).

this is huge for me, i have 2 ps3.. one with a broken bluray (updates work fine, btw as long as there is power to the bluray control board) and one good ps3.

i can backup with my good one now and use the broken one for more than a media server!

With regards to the compatibility issues with this "no disc" thing, maybe if the PARAM.SFO of a game is edited and the game type changed from disc based to hard drive based, then it will work better

I will need some feedback for all of you to let me know if they are working or not.

If you have a request for a specific board let me know but please don't ask for any pic boards unless you can give me the source, and don't ask for led's to be added unless you give me the proper leds.h or at least let me know what the settings should be for your board as I don't care about an led that turns off 2 seconds after the PS3 boots

Thanks for that. I think your tutorial was very helpful as it explained how to do this and also what this change's actually about, in detail. Most peeps were thinking that you could load all your games via backup manager without a disc in the drive, but your tutorial shows that this new method will allow you to boot only the one game which you have on your external USB drive, without having a disc in the drive.

Hope ppl can build on this and all games can be run without a disc in the drive, but this will obviously need a new backup manager, which I see someone's working on

I just got my blackcat usb today, is the general idea that I should flash it with this modified hex and use the old BUM til a new one is created? (IE this version still works perfectly fine with the old BUM just doesn't support the new features?)

Could not directly point to the location "dev_hdd0/LAUN12345/GAMEZ" ...?
