hi all,
I coded this little tool to remove checks for Firmware v6.xx in decrypted eboot.bin files just like for example Dead or Alive Paradise uses.

Actually it also seems that Kingdom Hearts Birth by Sleep also uses this technique but still won't run after patching.

Lemme know if it was usefull for you or in case u want the source...

PS: Requires .net 2.0 framework

It would be useful if you add the eboot.bin decrypter to your download and a small tutorial describing how to decrypt the files.


Falls jemand seinen Text nicht verstanden hat. Es soll ein Tool sein, das die Abfrage aus Spielen entfernt, ob eine 6.xx Firmware installiert ist und sie stattdessen für 5.xx CFWs kompatibel macht.

woooot?omg! works it with god eater?

oO very nice hope this will work with GodEater!

The usage is pretty easy. Just run the commandline tool and it will display all the needed arguments.
For example:
pspebootpatcher -i eboot.bin -o eboot_patched.bin

this will take the eboot.bin in current dir as input file and writes the patched file to eboot_patched.bin.

Keep in mind that the eboot.bin have to be decrypted! (Use EDecrypt 1.3.1 from mc707 for example).

What do you mean with "add to your download" ? I allready tried to add the file as attachment which doesnt seem to be possible if u ment that.

thx i will test it now.
works it with god eater/

It does not work with God Eater (JPN).

Its a decryption Tool?
I am trying for testing the Tool.
When
the Tool is good, say it thats.

Ist das ein Entschlüsslungs-Tool?
Ich versuche es mal zutesten.
Wenn es gut ist, werde ich es sagen.

bei mir funktionierts nicht...

I cant launch the Tool?
Its a Fake?

Ich kann das Tool nicht starten.
Ist das ein Fake?

Actually I was talking about the decrypter itself (e.g. EDecrypt) and not about your patching tool. I meant in the way that you are offering both apps together so the users have everything ready in one package.

Hast du Microsoft net 2.0 framework ? Das brauch man um das Tool zu starten meint er..

I would recommend the Hex-Editor.

Edit:

@pspcube: Ja habe ich, funktioniert auf jeden fall nicht, ich versteh nicht wieso das Compatibel sein soll.

This is definately no fake.
I coded this tool while I was reverse engineering "Dead or Alive Paradise [JPN]" Firmware version check. So this tool definately works on decrypted DoD Paradise eboot.bin to make the game work. While continuing some research I noticed that Kingdom Hearts Birth by Sleep [JPN] (which is still uncracked i think) does the same FW version checks. So dont take this tool by any means as a PnP noobish end product. it's for testing and development reasons mainly. Therefore I put the src in here so you know what is exactly happening and can use a hex editor for example

So this tool does nothing else then search for patterns like this (taken from DoD Paradise)->

1fd8cc: 3c020602 lui v0,0x602
1fd8d0: afb3000c sw s3,12(sp)

(this is actually a compare for fw version higher equal to 6.2)

and patches it to:

1fd8cc: 3c020500 lui v0,0x500
1fd8d0: afb3000c sw s3,12(sp)

while doing a lil research I found nearly the same pattern in Kingdom Hearts ->

8a7d424: 3c020600 lui v0,0x600
8a7d428: afb3000c sw s3,12(sp)
8a7d42c: 00809821 move s3,a0
8a7d430: 34440010 ori a0,v0,0x10

so it actually checks for firmware version higher equal to 6.

So with this knowledge of coz u can use a hex editor (assuming you aren't a n00b ;P )

Go and have fun ... or not

Great! I was always interrested in how those firmware checks works, but I was to lazy to try to find out myself
Thanks for the good explanation
I'll have a look at the sources when I have time
