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


Sponsored Links
200w 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).

3d dot heros - works from app_home/PS3_GAME Backup Manager Yellow Flickering
The yellow flickering is caused by trying to run the game in 1080P (don't ask me why). Change your display settings to 720P and it'll work, or at least it does for me.

A lot of games don't seem to work with Hermes' custom version of psgroove and backup manager. This is good for people without a working ps3 blu ray drive (because it allows them to at least get some games to work), but for everyone else it seems like its best to stay with the original Backup Manager and psgroove combination for now.

I think this development is really interesting, though not really useful yet for me since my bd drive is still working...

However, if i'm right this would MAYBE mean we could also launch from the internal disc drive? So you could burn actual discs and the play the games from them like a original ?

This would be cool, since i don't plan on archiving games on hdd forever
