Re: Finding the memory layout of the vita?

Is it too much to wish for a hidden debug mode? Maybe someone can get their hands on an official devkit and use debugging features to find memory layout?). There's this thread that talks of a debug mode. I can't verify its validity, however - note that the guy makes a video of a Content Manager fre...

Re: Just wondering..

It really isn't that impressive. It's just parsing (or even just reading) the unencrypted files that are on the hard drive.

Re: Finding the memory layout of the vita?

We (I guess excluding me since I don't want to poke around my $300 device) should also attempt a NAND dump. It is much more likely that the NAND is encrypted (I mean, even the 3DS has an encrypted NAND), but no harm trying. From reading the hacks of other consoles (PS3, 360, 3DS), there is usually a...

Re: Finding the memory layout of the vita?

I hope that the RAM isn't encrypted, logically, it wouldn't, as that would use precious battery and cpu cycles that wouldn't be an issue a console. But then again, it is freedom fearing Sony. Let's assume isn't encrypted. That means someone needs to do a hardware RAM dump in the worse case. I don't ...

Finding the memory layout of the vita?

I've always wondered how hackers on a new platform make use of stack overflows when they don't know the memory layout? It is required that they do a hardware RAM dump? But what if the RAM is encrypted? It seems like a chicken and egg problem to me. It feels like the top priority for the vita communi...
