are you talking about this?

yeah, and why wouldn't you extract some text to try to crack the compression?

Unfortunately not, it's pretty basic math functions... You can dump it by making a savestate with the emulator when the text you've chosen appears on screen, then unpack the file with winrar/7zip or whatever and you'll have a file that weights 32MB (eememory.bin, but I'm not sure, can't check right ...

yeah, seems a non-standard approach. Apparently instead of 1b flag 8b code uses 2b flag 16b code. With some strange variants...I'd need the uncompressed file to be able to crack it successfully. You can obtain it by looking for a compressed text file that you know appears in the beginning of the gam...

Looks LZSS

You need to take the last versione from here: http://buildbot.orphis.net/jpcsp

then in the options flag something like "export PDG"

How did you obtain them? I have almost all formats cracked but the scripts, I'd be very interested in that..

I'd like some help on this too

This tool extracts DATA.DAT from the ps2 version. You need SECTOR.H and DATA.DAT in the same dir as the tool. if it gives you a dll error just install vc++2010 and/or .net framework 4

Download

bye

[edit]If someone downloaded it, there was a little bug. Pleasr redownload it

they're password protected

could you link me some tool to unpack the PSAR file you obtain after the extraction of the PBP please?

mmm what if that second part is NOT encrypted? can you upload some smaller files?

the key just add 0x06 to the previous char...
ex:
first bytes of the key you uploaded:

79 7F 85 8B 91 97 9D A3 A9 AF B5 BB C1 C7 CD D3

0x79+0x06=0x7F +0x06=0x85 +0x06=0x8B and so on

when the sum is > 0xFF it just subtracts 0x100. Assuming it always starts from 0x79 do your algo

hope this helps

the LZ compression is the nintendo LZ77_flag_0x10

Here the tools
