I think in WinRAR you have to go to Commands>Convert Archive for compression options
By adding it to a .rar or .zip file, you compress it. I think there are ways to compress it more, but I'm too lazy to try and find out right now.Zitat:

Edit: X omega v5 beat me to it.
If on windows, just right click it, and hit add to archive. From there under the compression type choose best, and hit ok.
right, well i'll try and get it all done tonight, i dunno. is it absolutely crucial or can it wait til i get up in morning? (UK time remember)
What did you guys find?
Just a Java SDK for TO and his work on the decompiler
Depends, if you want any process potentially made tonight. I think someone else here has to be able to do this though.Zitat:

Sorry TO, it's going to take too long. It'll have to wait until the morning unless someone else manages to. Just get them to google what you described, that's how I found it. Got it down to 30.7MB in a best rar. Good luck
Thanks anyways.
OK for everyone, I need the javasdk for linux and I need it compressed to 30MB. Using winrar on the file right click, go to add to archive, under compression type choose best. After that, go to yousendit.com and send it to [email protected]
I'll give it a try. It's a pretty small file, so I should be able to get it done within the hour.
Edit: Is 30.7 mb fine? If not, is there any way to make it smaller? It is compressed in .rar format at the best quality.
Edit 2: YouSendIt Download Link
uh? decompiler for prx files? I don't know what use the java sdk would be for that.. however,
I would load it up in IDA mips cpu instruction set .. that works
The GPS drivers and such have access to flash1, not flash0 :icon_surp
in 2.7 it creates a /gps/ folder in flash1 root
Can I have you do something else? Download the Windows offline installer. Do the same thing by choosing Best. Under it should say split, put 30mb.Zitat:

I'll get it up as soon as I can. It should be done within half an hour.Zitat:

Thanks a lot. You have been a big help. I really do appreciate it.
Again thanks a lot :)
While I wait for it, I have another exploiting project to look into via the serial port
I gave him a copy of Skylark's PSP ELF disassembler. It uses Java. It's much better suited to this than IDA is because it resolves the NIDs used in the programs, so you get actual PSP function names.Zitat:

If it is up and running, could you post a download link here so we could all give it a try? Or are you only giving it to certain people untill you are ready to releae it?Zitat:

P.S. TO, the second part is up.
BTW TO, it seems like you have Linux instead of Windows. Isn't it harder to use than WinXP when in combo w/PSPs?
I myself have some bad experience from SuSE 10.1 that messed up my mouse...
However, since I've now got a modchip I'll be more than happy to try any 2.70 bugs/exploits (when they're found).
I have XP installed and use a live cd linux when needed. Im installing java now, and then I will get to work on decompiling.
Hm :/ do you have to pyshicly upgrade to 2.6 to run the prxdecrypter? Cause Devhooking to 2.6 seems to not work with the prx decrypter most likley because the flash0 is still 1.5...?
:P
Check you PM.Zitat:

It worked for me...
Hm, really? I end up with the none decrypted dump >.>Zitat:
Zitat von Xay_J
you decrypted from devhook?Zitat:
Zitat von Xay_J
what app can I use to look at prx's so that I can help.
Well how do I tell if its the decryped PRXs or not?
it has to be xxxx.prxZitat:
Zitat von Xay_J
sure you can devhook it? I'd been thinking about joining the search, but been spooked about using devhook for the 2.6 part. Prob enough peeps looking into this, but ya'll neva kno'.....
btw; TO, got pm...
Guys, I've been looking at some of the prxs in a hex editor, and found the partially readable stuff. Is there anyway to convert the hex into it's ASCII text, so that I can actually read it and find out when one command ends and another begins? You guys seem to be coming up with strings of commands. HOW?!
If you scroll down in the hex editor you will find some reable stuff.
I have, and this is what I get

What PRXs are you looking at?
The above code is info on how the PRX was compiled. (I think)
Nevermind. I found the proper stuff. It was isofs.prx, and the code is
So what is this? Creating an image of the UMD? Requesting kernal? UMD9660 - ISO9660 anyone? Or am I going on completely the wrong tangentCode:Removed due to copywrite
I think that this code shows some kind of request for the use of Kernel. Maybe to verify UMD...to create an image of the UMD...
I think it's trying to veryify the image on the UMD (hence the 9660 stuff?). Not too sure. I've found a load of things requesting kernal though, but I have no idea if any can lead to an exploit. usbcam.prx has crap loads of things in it
Is anyone working on this still? Everyone seems to be interested in the serial thing, lol.
Anyways, guys, is there a certain command I should be looking for here? I keep seeing loads of things to do with kernal, but I'm guessing none of them are exploitable. So giving me something to go on would be a major help.
Those are just standard kernel calls to manage errors and stuff like that. Non exploitable. I have to dissasemble the files still, and I an still looking into the serial port thing.
Considering we don't know anything about how/where the exploit will occur, there isn't much more info to give you. TO is going to try using a decompiler to try and find an exploit. In the mean time, just keep looking for anything interesting.Zitat:

Correct me if I'm wrong, but isn't that info you posted copywritten? Or, in other words, shouldn't be posted here?
