PSP UMDs hacked

Another step forward in the race to crack open the PSP: ps2nfo.com user Paradox worked out how to get a dump from a UMD disc, and has released the ISO files for several PSP games (Wipeout: Pure US, Ridge Racers Japanese, and Vampire Chronicles: The Chaos Tower Japanese). Also of note, UMD discs use the standard ISO9669 format, so the released ISOs can be burned to regular CDs or DVDs. Know that the games are not yet playable in this format, but it’s a big step forward now that all the reverse engineers out there can get their hands on this stuff.

Obviously I won't post links to them (even though you can't play them) but ISOs for every PSP release are slowly making their way to torrent sites. Looks like that went pretty damn fast from being able to run homebrew to creating a UMD ripper.

Also up on pspnfo.com is the first helloworld application. of course you need a JPN PSP 1.0 to run it.
 
well, for those anti-pirates (yeah right ;) this is still huge news. This will be the first chance wanna be emu-porters will have to take a look at real PSP game code. I have to imagine we will see the first working emulators no more than 3 months from this day.... if even that long.

of course the second question then will be how long before those emulators will be able to run on 1.5+ systems.
 
so far the largest umd is about 600MB. I'm betting they were ripped via USB..sony am crying. Its only a matter of time before unlicensed software is running off of memory sticks..the only question is if sony can stop the problem with more and more firmware updates.

When this happens, I will definitly buy a PSP. Even if I never buy a single PSP game, I'd still be happy with the purchase.
 
Have any of the umd movies been ripped?? I'd be interested in seeing what format they are(mp4 probably)and the specifics of the bitrate and such.

Wipeout is around 150MB... Vampire Saviour is around 435MB...

That small? I'm guessing all UMDs so far are single layer then (900MB)?

edit-Actually 435MB for DarkStalkers sounds kind of crazy given that Vampire Savior was only 43.4MB on CPS2. What's all that extra memory spent on? :/
 
here is an interesting tidbit from the Wipeout NFO

Since this contains the ability for "web browsing" its hoped that an exploit can be found that will allow the booting of code on any version PSP. Check the unencrypted files on disc for more info on exactly how the browser works.

I was able to load arbitrary code (NOP's followed by a JMP loop (essentially a 'halt') by editing a Wipeout Pure "ghost" save file. I believe this exploit may be extensible to the Wipeout Pure game save files. If so, this may be a good entry point for a bootloader.

Unfortunately, while executing NOP's is an interesting start ... I'll need to bone up on the instruction set of the PSP cpu before anything useful can be done with this.

The entry point to edit and insert an overflow of NOP instructions is at offset 0xA14 in any ghost save file.

Be very afraid of the internet
 
ok so you got iso's.... what the heck is that gonna do for you??

Until those things can be run off the memory card or put on blank UMD's, they're not much use to the pirates.

but to the non-pirates, as has already been posted in this thread, you can do stuff like check out the innerworkings of games for stuff like emulators, or look for potential exploits in games that allow the loading and execution of arbitrary code, aka allowing all non-1.0 versions to run unsigned code also, through like the web browser or hacked saved games.

this also potentially helps the pirates greatly, but we won't go into that on this board.

Not really. They could come up with a PSP emulator and let you play the games via ISO.

Yeah like how they came out with a PS2 emulator that lets you play games via DVDISOs.... oh wait. :lol

Sure, it not a boutique architeure like PS2. Dreamcast emulation might be a better example of what to expect.
 
There was talk about PSP debug kits streaming games to PSPs. Maybe that feature could also be exploited?
 
This has potential to be a catastophe if the pirates are able to run ripped executables from a Memory Stick.

Business model that relies on tie-ratio around 7-10 games
- The convenience of a 2GB memory stick - that can hold 2-3 games
- Combined to the fact that Sony is actively teaching people to run stuff from a Memory Stick in PSP
- Better battery life
- Potentially shorter load times (not sure about this)

= RUH ROH

I don't think the PSP is powerful enough to emulate the DC.

Powerful enough to run ports of DC games? Yes.

Powerful enough to emulate the DC hardware? No, I don't think so.

I think you missed what he was saying.
 
from how the PSP seems to behave when loading or saving, I wonder how effective a memory stick would really be able to play a UMD rip. It seems like it might be too slow.

streaming from the network would likely work, but if the GCN is any indication, it probably wouldn't be that hot either depending on what kind of speeds you could get from WiFi.

but I agree with others. I am more interested in getting homebrew emulators to run.

This is the first piece of PSP homebrew news worth getting excited about, to me.
 
*Sony executive walks into PSP programmers office*

"Hey.. Bill. You know that e-mail and chat program we're making for a december release? We ened it tomorrow."

And doesn't this mean that this combined with the other warez news makes it so that warez'll be able to run on a jap unflashed psp?

reading from a memory stick is faster than reading from the umd
 
this is a scary thought

Why is this scary?

Not for a gamer it isn't, but for a developer / publisher / platform owner / retailer it is terrifying.

- Gamers able to get a superior version (faster loading, better battery life, multiple games on a Memory Stick)
- In a very convenient way (from home, maybe even before street date)
- Directly to their device
- And there is not much Sony can do to prevent it happening (USB dongles?)

The pirating is scary, I don't think direct to device makes it any scarier.

Well think of it this way - you are in Starbucks and get a call from your friend that GT4 Mobile has been leaked a week before the streetday. You fire up your PSP, download the game and off you go.

We've come a long way in PSP acceptance that no one has yet made the obvious joke about the battery dying long before the download is complete...although it probably would ;)

But, to address your scenario specifically, you still have to be a person of a certain persuasion to be willing to pirate a game, no matter how convenient it is. And it's not as if only being able to download over a wired connection is so much less convenient to begin with.

Because the thing is already OUT, and we realize the battery isnt nearly as bad as fanboys would like us to believe.

Indeed. I was actually very wrong about the battery life back then - wrong enough to get two extra batteries with my PSP.
 
"Yeah like how they came out with a PS2 emulator that lets you play games via DVDISOs.... oh wait. "

Ehrm... If that was supposed to be irony, have you never heard of HDLoader? Essentially a (commercial) hack that allows you to play games stored on a hard drive as disk images. Sure it wasn't an emulator, but still. It's a way to run games without the original disc.

Since the PSP can run software from the memory-stick, you wouldn't need a disc like you did with say HDLoader, making it even simpler for pirates.

Sony would probably update the firmware constantly to get around it, but it's definitely a problem.

However, if it can lead to a large user-base, maybe it's a price worth taking. Provided they can get around the issue the next time.
 
This is wonderful news, I still think the BIG issue left is finding a way of tricking the psp into playing games off the memory stick, this will be the hardest part because it may need a modchip.

I guess you don't know what "emulator" means.... oh well. :lol
