Japan Wipeout Downloads Released, New User Agent ... (more)

[plmars]

I feel so bad for triple posting but I just realized that PSP has build in zip functions. It has to somehow read that zipped data file doesnt it?

[Histo]

Yes it extracts the zip file or the browser does. The default zip path is

data/PSP/SAVEDATA/UCJS10007DGAMMAPACK1/


Just FYI

[Histo]

the file:/// is more my speudo word for referencing a storage device.. mainly the memory stick... i havent seen anyone anywhere post the name for this so im not going there until someone figures it out.

Try data Thats what their zip file reference the stick as.

[chaos]

i have the north american version of the psp and wipeout.

i made a mirror of the wipeoutpurepsp.scej-online.jp site on my local web server, and directed the wipeout browser to it.

the browser loads up the download page perfectly, but when it comes to the actual download, it doesn't get far. according to my logs, it downloads the pspdif file from my server ok, but the psp spits up "an error has occured during download"..

the fact that it calls it a "download" tells me that it's actually trying to process the update, but it seems that the us version can't (or won't) handle the jp pspdif file. it never makes a second request for the dat file.

pspdif: psp (d)ownload (i)nstruction (f)ile

just a guess..

[pedroleite]

What if...

• each publisher makes it's own AES keys, 256 bit version.
  each file in the PARAM.SFO file stores the IV (initialization vector) - one of the changed areas on the file list contains this 16 byte binary data.
  The TEST.BIN file has only a 16 byte chunk from mandatory output from the AES-256-cbc (is this confirmed?)

If these were correct, the download.pspdif, could be a small executable, it appears to not be 16 byte aligned (almost every single data area, or file is), so there should be a 6 byte header/trailer at least.
One assumption I could make is that the file should contain the next file name.

I tried, openssl as a tool to experiment with the random areas hex values as IV and keys, no luck so far.

I think the EBOOT.PBP couldn't work this way so simply, either we have a key in hardware or the key is there... I remember seeing a pointer on my file to 32 bytes less than the PSAR file (looked like a key).

The original download.pspdif should work only with the Japanese version of the game, but should download and expand any zip? Anyone tried it like this?

I have a JP version PSP, and I'm waiting the US Wipeout Pure to check this.

Also... anyone tried making a *.PBP file from the files of a SAVEGAME? to see if it's recognized? Maybe it's just a simple format for internet deployment of file packs.

[HeWhoKnowsNowt]

I wouldn't believe that Sony would allow any developer to produce signed code in any form.
After reading through various threads it is becoming clear to me that if we find an exploit in any form it'll be quickly plugged and no doubt someone will get an emulator to run on a psp devkit but that'll be a far as it goes.

[DBG]

Devkits already have an emulator for testing, greedy bastards ;).

I'm trying to focus onto param.sfo cracking because it can help so much in the future. One little update on it. Every single param.sfo has the same exact langth which makes reverse engineering so much easier.

yeah, i made a program for that. it's the PBP explorer w/ sfo editor. and the param.sfo is variable length. i have some that are big, and some that are very small. it's only name/value pairs. nothing terribly special kinda like a mini-database.

I have never seen a bigger one. Sorry, my mistake. I still have no idea regarding its key though.

[ooPo]

A database, or environment variables for the executable included with the PBP.

[thingsimade]

Here's a mirror of the file for anyone who couldn't download it

[annerajb]

what file are you talking about anyway yes is a good idea to mirrior it give me the link so i can look at it

[kenwest3]

what if you save it as is and then open it in microsoft excel as a data file and allow excel to format it for you

Wipeout Pure Gets Downloads (PSP)
http://ps2.gamespy.com/playstation-port ... 590p1.html

...

What do you think about these homebrew hacks that lets gamers browse the web via their PSPs and Wipeout Pure?

The browser in Wipeout Pure is one of the ways of getting extra content for the game onto the Memory Stick and has no other function. It was not intended to be used as a browser, so it is not optimized for that use.

why is pi.wad bigger in one of them?

3659264 PSP/SAVEDATA/UCUS98612DGAMMAPACK1/PI.WAD
3637248 PSP/SAVEDATA/UCUS98612DGAMMAPACK1/PI.WAD

[Herben]

Moved to PSP General.

[csyria]

I went and grabbed the data.pspdat file off the official site myself, and I opened it up (just change .pspdat to .zip).

PSP/SAVEDATA/UCUS98612DGAMMAPACK1/pi.wad is listed as being 3,552 KB in size.

AFAICT 3637248 is the real size. I'm not sure where the differnce comes from.

[reality]

I tracked down gamma2. I am planning on getting wipe-out pure so I already download 1 and 2. UCJS10007DGAMMAPACK2. I got it here if anybodies interested.
