Finding the memory layout of the vita?

[Green Ranger]

I agree that we should not use anything acquired illegally. I am talking about an acquiring an actual physical dev kit though, not the SDK. In an unrelated note, I am in the PS Suite beta, and the tools do not currently support the vita.

What can we expect from the PS Suite ?...it's not likely to write an programm and it runs on the Vita or it would just run in an Sandboxed Enviroment...just thinking. And Mathieulh...he's a talented dev but i hope he could work together with other dev's and not just giving hints. Wololo's site is a good example to show, how the szene could work together and sharing/keeping things.

It's a little bit offtopic... but here GDC ps suite presentation.
It runs in mono (c# opensource implementation), so it's like in java where your code runs over a virtual machine.

Look. Now I did say SDK in my other post, but I meant it very indiscriminately. Do I know if what he was talking about was a software dev kit or a hardware dev kit? I most certainly do not. And unfortunately I don't have the luxury of archived conversations with the guy so I can't pull it up and reread it to make a more accurate confirmation. But either way, I'm finished discussing this matter publicly... not just because of legal repurcussions, but also because maybe he doesn't want everyone to know what I'm discussing. I was actually kind of hoping that moderators here would censor any and all references that I've made to Math and any dev kit he may or may not have.

On a side note, I sincerely doubt we would be able to JTAG the Vita. Also, wouldn't it be possible to encrypt the ram if there were some kind of encrypt/decrypt chip handling the data in between the ram and the cpu's data flow?

I hardly think he can get a hardware dev kit (if such a thing even exists). And even so, I highly doubt that HW dev kit will give you any sensitive information about PSV's internal architecture.

Also, wouldn't it be possible to encrypt the ram if there were some kind of encrypt/decrypt chip handling the data in between the ram and the cpu's data flow?

I never said it's impossible. But that hardware is not as easy to build as you might think, which would mean increased cost, slowing RAM access by probably at least 5x, and consume way more power. Not very likely on a portable console like PSV.

Is it just me, or is the RAM embedded with the CPU?

Looks like so.

is there anywhere on the net where i can learn this stuff?? I want to help you guys out... also i donate my vita to you guys to test any hardware hack you might have, i bought it purely to try and help with the hacking. So yeh a link to read up on thisstuff would be much apprecited

Another possibility is breaking out of PSP mode somehow, but where do we begin with that. I still say the "easiest" thing to do is to get a devkit and use remote debugging features to find memory locations. If anyone knows anyone with access to this, PM me.

We would have much better luck getting the info we need directly from Sony. Although it is possible, it's very unlikely that this could be pulled off.

Well... no. It needs you to know a lot of stuff, and (reverse) engineer it. That is, knowing what stuff of all you know you should apply. The only way to learn hacking is actually (trying) doing it.
