Silent Hill Origins *.arc and Obscure *.hvp archives

[Rafulpower]

Hello! I am new for here.
I need to unpack/pack *.arc archives from Silent Hill Origins [PlayStation Portable].
And unpack/pack *.hvp archives from Obscure [PC].

I want to translate the texts for Portuguese.

Thanks.

Wrong forum. Needs to be moved into Game Archive Research.

[Rafulpower]

I'm sorry. I posted in the wrong place. It can move without problem. Thank you.

[Rheini]

Please upload some sample files.
(preferably not rapidshare, http://uploaded.to is quite good imho)

Had a short look. Here's my current template which might be horribly wrong:

Code: Select all

local uint fpos;

struct Entry {
	uint uk1;
	uint offset;
	fpos=FTell();
	FSeek(offset);
	uint uk2[5];
	string name;
	FSeek(fpos);
	uint uk3;
	uint uk4;
};

uint magic;
Entry directory[36]<optimize=false>;

However this archive contains only video files. Even if you managed to unpack it, you would have to somehow convert the AT3 movies.

Are there other ARC files?

[Rafulpower]

Yes, there are other ARC files!

SH.arc - 270MB

Part1 - http://uploaded.to/?id=5s5n8j (229 MB)
Part2 - http://uploaded.to/?id=ksciu1 (25 MB)

Thanks.

[Rheini]

Thanks.

Code: Select all

struct Entry {
	uint FilenameOffset; // Offset in the string table
	uint Offset;
	uint Size;
	uint DecompressedSize; // 0 if it isn't compressed
};

char magic[4];
uint NumFiles;
uint OffsetData;
uint OffsetStringTable;
uint StringTableSize;

Entry directory[NumFiles];

This is the correct one. Files may be compressed (best compression level) with zlib(otherwise DecompressedSize is 0). Decompress them with zlibc.

[Rafulpower]

Wow.. thank you very much. Excuse my ignorance, but I don't know how to run zlibc.exe!

How do I do to extract files from SH.arc using zlibc.exe?

Thanks.

[Rheini]

Oh I'm sorry, I didn't mention zlibc is a pure zlib de-/compressor.
It is no ARC unpacker.
You have to extract the files manually, then you can use zlibc to decompress them.

[Rafulpower]

Right.. I will try. Thank you once again.

And how can I extract the files manually?I cant extract it with any app.
Which application did you use tu unpack sh.arc archive?

A hex editor, that's why I said "manually" i.e. by hand.
I use 010 Editor, the code I posted above is a 010 binary template.

Ohh,now everything is clear!
