Thank you, good sir! Extractor works nicely.
Wouldn't you mind to share recompression alg code?
Don't have much patience to wait fully functioning tool

This is the complete code I'm using to decompress and recompress; it is a pretty standard implementation, with a top of 16 byte os compressed strings:

Re: Corpse Party PSP image.bin file
I'm sorry. But you can do the opposite? That is archiving folder IMAGE in image.bin?
I want to replace some of the texture.

Re: Corpse Party PSP image.bin file
Thanks for the code and for the app, but I'm having a problem.
I've tested your app with the 10Mb file that other user has uploaded and I get an exception. Can´t a partial file be used?
I'm interested in traslate game into my language, spanish, do aby of you know how can I get string??
Thanks!!

Re: Corpse Party PSP image.bin file
The 10 MB sample most likely won't work cause it's trying to decompress or go to some offset that may or may not exist.

You are right, I've tested it with full file and works O.K.finale00 wrote:The 10 MB sample most likely won't work cause it's trying to decompress or go to some offset that may or may not exist.
Any idea about were can I find text's files??
Re: Corpse Party PSP image.bin file
They're stored in SCRIPT folder. Check file SCRIPT_MAP5 (CHAP1) - these one have introduction of chapter 1.Any idea about were can I find text's files??
As I checked they're seems compressed and contains bitmaps / voice acting/ avatars.
