September 21, 2010 // 6:23 pm - Today Spanish PS3 developer Hermes at (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 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).

Thanks for taking the time to clear that up, I thought i was going mad for a minute there! USB HDD was in the far right port and it did all work except for the BM but if its not meant to work with this version then no problems!

is there any chance whatsoever of this being ported to the ipod 1g at all with psfreedom? is it a feasible option? or will it likely not happen? (got 3.41 ps3 but drive packed up so if it was able to work with ipod i'd be in heaven )

great work peeps and loving the progress!

Used ZDS to compile, and wabbitsign to convert the resulting hex to 8xk.

capnick: it's made to not work with BM. This hex is for mainly booting EBOOT.BIN from PS3_GAME but it should still run your backups from the BM from what I was told.

Also make sure you are plugging your USB HDD or Thumb Drive in the farthest right USB Slot. As for a patched led hex that aint gonna help at all. I need to know what led to turn on and off ex. (1

if you get error messages it usually means your external hd isnt recognised by the ps3 (yet) either wait or try and load it off the xmb via something else

It means your title needs to install game data.. Like 50-60% of the PS3 games..
