PS Vita emulation progress

[ssshadow]

I just don't think that integrating vita emulation in rpcs3 is good idea (if totally different codebases). Why not separate emulator for it?

It probably is a good idea, otherwise Neko and maybe others wouldn't do it. I just don't understand why it is yet.

(and even if we had full working vita emulation it's still would be sort of useless as there is no way to back up isos or something. Only like writing simple homebrew that wouldn't run on Vita anyway until it gets hacked which may be in 1 year or 2 or never).

Future proofing.

[Nekotekina]

Of course, PS3 and PSV are different systems, but not absolutely. There are many general things which may be useful on both platforms simultaneously. And the fact that they both were made by SCE only amplifies things.

I can't say much, but it would be harder to start an independent emulator, and it wouldn't be helpful. For example, memory system for 32-bit pointers with 4 GB virtual space, this part is shared with zero overhead. I don't even try to foresee how many similarities they could have, one would probably understand the benefits working on both platforms.

So is the final goal here to some day run commercial Vita games?

Maybe, it could possibly run games someday, why not? But I see only "advancing" as a current goal, not a "finalizing" something.

(and even if we had full working vita emulation it's still would be sort of useless as there is no way to back up isos or something. Only like writing simple homebrew that wouldn't run on Vita anyway until it gets hacked which may be in 1 year or 2 or never).

How I like this scenery, fully working emulator and no way to rip games... But such extremes are impossible.

It probably is a good idea, otherwise Neko and maybe others wouldn't do it. I just don't understand why it is yet.

I can't prove that it's a good idea, I just like it (but hesitated before). Another factor is PS3<>Vita communitation, but I don't know about it.

is there any way to unpack psvita package files? i think they end with .psspac

EDIT: i didnt think winrar works for this lol

You try unpack .pkg Vita files?

Some other hash samples work too, but I didn't verify them.

Yes, we should be able to extract the .PKG file.

And i cannot unpack .psvimg

[BlackDaemon]

It's impossible atm. No keys to decrypt pkg and eboot.bin inside. Also, .psvimg it's CMA format, and it's using different encryption way.

For .pkg unpack need AES key.But its very hard(find AES key, i think).

how is the project going guys
