No HEN? No problem. This PSP homebrew runs on OFW - Page 2

1. No HEN? No problem. This PSP homebrew runs on OFW
2. Details and download

So, how does it work? Kgsws explains:

 

Simple, notice it contains ~PSP header from demo game (UCES00206), it is exactly same header. It is easy to craft last 16 bytes of encrypted data block to match header CMAC - yes, that's the trick.

 

There are some strange thigs, it can't run homebrews with bigger executable block (data block does not matter), and because of ~PSP header, it has to match exact size of original game.

 

psp-go

 

If you want to try it out for yourself, you can download the file below. Just make a directory under PSP/GAME, stick the eboot in there, and run it from the XMB. No HEN or CFW needed.

Unfortunately this opens the door for -every- kid with a PSP to bitch and moan like somebody owes them a backup loader so they can pirate. :\

That door was opened YEARS ago with Pandora. Where have you been?

No, when pandora came about, CFW already had an ISO loader. No bitching and moaning required.

Seriously, it does not, only user mode stuff can be signed, not kernel mode. Which means, all of those "kids" should know they ain't gettin' ISO's. :D
And if not, they'll learn fast enough. :P

The people who go around begging and whining for hacks are not the people who even know what the differences between those modes are.

I was saying that since this brings homebrew to more PSPs, there's now a larger potential audience... and since it encompasses previously-unhackable PSP's, it's likely that the ratio of people who don't know any better will be larger.

Well, it's like a mobile phone now (signed / unsigned)?

You can simply sign the apps and it'll recognize as official software.

That's so kewl!

ever since i came into the psp scene i always thought about something like this. (instead of hacking the firmware why not make the homerew work on official firmware). but i was like 11 and i didnt know the complexity of this stuff yet. it might e time to fix my psp and come back to the scene.

This would be a great compromise with sony if they allowed Emulators (Nes, Snes,Atari,PSx, etc..)and home brew to run but not any present PSP games. This would end that annoying CFW Vs OFW war. Heres hoping :lol:

My fear is that, because the homebrew would use Sony's keys, this and many other sites may view them as something akin to ROMs and not allow them to be hosted. Or, at first they do allow them, and then Sony threatens them and they yield, like some do.

It's too late to try to block hosters from hosting ROMs because they're everywhere.

they actually don't use any Sony code, they just have the same keys... its complicated to explain but technically nothing is illegal with this piece of software.

Maybe they can shut down the internet.

That might be a problem in china.

Except that piracy is even worse there.

because they use keys, its legal. you cannot copyright numbers and thats what the keys are, hexidecimal numbers used in an algorythm to sign and encrypt.

It happened before with HD-DVD.

Now I can finally use ofw on my psp and use homebrew. I can't wait for a homebrew signing app to get released. I don't really care about iso loaders, all I care about is running emulators like nes, snes, and others.

And, you want to know WHY?

This is for every single person who was on the receiving end of the long-shafted raping by Sony when they purchased the $250 PSP Go product. A product which up until a couple of weeks ago was limited by PSN having next to NO games.

This is for every PS3 owner who was on the receiving end of the 'Linux debacle'. Owners who paid for a machine that they want to use THEIR way. Why? Because, that's what they paid for.

And last,
The prospect of this release is a beautiful, "Thank You" note from all of the loyal consumers who believed the lies from Sony, and 'ate the cake.'

Let Freedom Ring!

# Great stuff, but not without consequences...Alexander4555 2011-01-19 00:13
This is an awesome innovation but like everyone said here, it is going to lead to more piracy. Considering any homebrew could open now, you're going to have teams of people working on a fully fuctional iso loader(if there isn't one already).

I do praise the developers and I understand that they did this for all of us who enjoy our emulators, apps, and homebrewed games, but the vast majority of people(kids) whom I encountered all what their PSPs hacked for the sole purpose of "playing free psp games." Sad but true.

Piracy is becoming rampant and its responsible for damaging several industries, such as the PC console market, the Manga, and American comic book industry, and the list goes on.

Its understandable that the economy isn't good but damn, what does it kill people to support their favorite video game developer by buying the game they enjoyed. For some reason they can spend time buying fast food at their local McDonalds but not a video game? What a bunch of leeches.

with the "Rampant"piracy idea. From where i'm at, most people say "naw, I'll just pay for the kids games because it's easier." I have only met one other guy attempting to cfw or trying to use flash cards. So i say the ratio is 1 pirate to 5,000.

# RE: Great stuff, but not without consequences...UltimaXX 2011-01-22 20:31
I sort of agree with what you're saying, but thought you could do with the heads up; McDonald's and other fast food stores, especially smaller non-franchised stores, were amongst the hardest hit businesses during the recession. People evidently cut back a lot on their Maccy Ds, too.

being able to sign and run homebrew on OFFICIAL firmware is what we really needed. the only reason why i got custom firmware in the 1st place was the fact that i can play nes and others on the psp. i want to get the latest model of the psp but not running homebrew on it was holding me back. this is a wonderful thing to have. and on top of that i can go on the psn network and not worry about being blocked with CFW.

Don't think iso loaders will be signed. you can't use kernel mode prx files in signed eboots AFAIK. no ones had luck with a user mode iso loaders, there've been attempts.

running the HEN through the XMB is completely reliant on the kernel vulnerability being there. Once it patched, the HEN is useless for people who update or get PSP's with new firmware, signed or not.

All this means is good IMO :lol:

That could be how AR got through :-? I don't know though. And if they did do it that way, it can be blocked by $ony as we saw with the AR.

If not, then damn $ony is crapping their pants now I bet.
