Ps3 Loaders V1.1 For Ida V5.2

[sephirothff]

salut

voici un peu d'avancement sur le hack de la PS3 ou tout du moins le désassemblage des fichier de la machine , voici le readme

PS3 ELF/SELF/PRX/SPRX PPU Loader v1.1 for IDA v5.2

:: Overview and Install

!!! THIS WILL NOT WORK ON ENCRYPTED FILES !!!

This will let you easily disassemble PS3 elf/self/prx/sprx files for the PPU.

SPU files are not supported and neither are encrypted PPU files.

:: Install

1) Copy "ps3.ldw" and "ps364.l64" and "ps3.xml" into your "ida\loaders" dir.

2) If you have not already installed the PPC-Altivec plugin it is highly

recommended to do so before using this loader as it will then support

the additional "altivec" instructions. (The altivec plugin is also

available from xorloser's site.)

:: Loading an PS3 File

Once the loaders have been "installed" you can load an PS3 file just as you

would any other file in IDA; you can drag and drop it onto IDA or choose "Open"

from the "File" menu.

If you tick the "Loading Options" checkbox on the IDA "Load a new file" dialog

it will ask if you would like to convert all executable sections to code.

This option isnt usually needed and so requires "ticking" to enable it.

:: Notes

* On slower computers it can take a while for the loading to complete and the

analysing to start. During this time it may appear like the loader has

crashed or frozen, but give it a couple of minutes before killing it in case

it is just working hard.

* When selecting to setup "Official Procedure Descriptors" (OPD) functions and

rtoc values the loader will take a lot more time than usual. However the result

will give you a much more useful disassembly to start looking through though.

So if you just want a quick look you might want to cancel OPD processing, but

if you plan to look at the disassembly in depth it is suggested to wait the

extra time. After all if you were to manually do the same processing that the

loader does for you it would take you forever!

* Analysing on bigger files such as the elf/prx files used for PS3 can take

some time, just let it do its thing. This is normal for IDA and is not a part

of this loader so cannot be sped up.

* The loaders have been compiled with the IDA v5.2 SDK and so should be used

with that version of IDA.

* Currently the loaders use the XML file "ps3.xml" to determine

the names of imported and exported function names as well as syscall names.

This can be edited in a text editor to add new import/export/syscall names.

Salut,

Loser passe à la PS3.

[ryaku]

Peux tu expliquer un peu plus clairement de quoi il s'agit et quelle avancée cela peut amener ?

[sephirothff]

vu que j'ai pas de fichier a tester je peux pas trop dire quelles infos ca donne (les infos sont dans le readme) mais c'est principalement pour faire de l'analyse de fichier (hélas non encrypté...)

c'est plutot dédié aux codeurs et hackers en somme , et ca fonctionne sous linux ppc , soit sur la ps3

[ouasse]

ça permet de voir comment les exécutables ps3 sont foutus, donc en gros comment on programme la PS3. mais aucune chance de pouvoir programmer sur le game os bien sur.

par contre pour trouver des exécutables non cryptés, on fait comment ?

[sephirothff]

bah justement c'est ca la bonne question :lol:
