Re: 1.69 or 3.18

1.69 is much much better for hacking, so if you want to do any of the hard work yourself, 1.69 is a much better path. If you are not looking to do much work yourself, upgrade and play games. If you want to sell your 1.69 to a dev who could use it, even better.

Re: Why can the PS Vita emulate PSP games as well as it does

Pretty much unless it goes through a Kermit interface, its hardware. When you say "different keys" what are you talking about?

Thanks!

Re: PS4 1.76 Webkit ROP POC

The 64bit version is a bit different. It is the same heap corruption via the sort() bug, but from there its different. On 32bit you can set the Uint32Array to 0x40000000 size and access any memory. On 64bit, you have to carefully change the base address since the 0x40000000 trick doesn't work for a ...

Re: ROPTool released by davee

Not thousands of hours, but it does require you to have some good dumps of as many of the modules as you can find. You'll need to find gadgets in those dumps to use to generate the rop gadgetmaps. It does require some kind of native exploit in order to trigger a stack or heap corruption to deliver a...

Re: ROPTool released by davee

This is an awesome tool. It does require some investment ahead of time to build all of the gadgets and maps needed, but once you get all the gadget work mapped out, its really productive. This is not for general programming. This is to help advanced developers investigate and experiment. Of the 3 co...

Re: Creating our own pkgs?

Remember that pkg files have ECDSA signatures and RSA signatures in them. Since the signatures on the pkg cannot be created, the AES keys are irrelevant. pkg installation will check the signatures, not just decrypt the pkg with AES.....

sorry to ruin your plans.

Re: [POC] Beta PKG Installation on retail 3.15

Keep in mind there is a difference between signing and decrypting/encrypting. We cannot sign game pkg files on the PSP, PS3 or PSVita. They all are signed with the ECDSA Key: x=0xE6792E446CEBA27BCADF374B99504FD8E80ADFEB y=0x3E66DE73FFE58D3291221C65018C038D3822C3C9 We don't have the private key for t...

Nice, great, splendid, impressive. ...What about describing the process more precisely? and more importantly, how does he get OFW to run unsigned code? he talks about all this game developers ***, but game developers work with devkits so they can run unsigned homebrews, we don't, we have retail uni...
