This kind-of fit multiple topics so general it goes. I am working on building some schematics for the PS V!ta. As large of a project as that is, I'm thinking I also want to draw up schematics for the devkit edition. One problem, I first need a devkit before I can rip it apart. So here is my first question, is there anyone out there that has one that would be willing to send me some photos? (A donation would be awesome but that's probably asking too much.) And the second, after I'm done reversing it, who would be interested in a devkit devkit? No not a typo, I'm talking about building a tool designed to develop and develop upon itself. What I mean by this is, I'm basically making a devkit from scratch. But it's kind of boring to make something that has already been made, so I plan on making a few things better like a fully accessible NAND pins for flashing on the fly, access to pins on chips otherwise unaccessible etc. (Plus the devkit is a little bit copyrighted. This will be a electrically similar, completely new device that just so happens to be compatible with the V!ta.) Interested? ( I know in not allowed to sell anything yet, this is just to gauge interest and to see how many are out there who haven't given up on the V!ta yet.)
How do you encrypt a pcb? Yes I realise that the data is encrypted, I have no intention of trying to decrypt it. If it leads to decrypted data, lucky us. What I'm talking about is a hardware level hack so we can have pin headers to practally any pin we like rather then trying to solder to all the smd components. (And to the bottom of ic's, like really how?) Like this, Spoiler: Image All of the green pins connect to a pad on the pcb but don't seem to go anywhere. I'm willing to bet that some of these not-connected pins are connected on the devkit. what i propose is to make them all available so they can be logic analyzed and figure out what we have. As Katsu has pointed out with his HFW, we don't need to decrypt the FW to get some pretty sweet hacks.
While this would be neat I wouldn't take anything Katsu has said to heart. Most of his work has never seen the light of day like his HFW or his Cobra "White Fin"
True, Katsu doesn't really release things in the usual fashion. His HDMI out mod took quite some time, finally someone got through to him and got some enough details to replicate his work. I agree with what you said about taking it with a grain of salt, but I wouldn't completely discredit his work just because it hasn't been released. What really gets me is this: Spoiler: Image 196 pin grid, less then 20 actually being used. This is of the eMMC, surely there is something we can do with all those pins.
