The Capcome arc files are almost always the same. I have researched them in the past for dead rising. I quick check shows the formats are the same, although I'm not sure if these ones use zlib.

Code: Select all

Arc Layout

Header:
0 - Magic - Chars(4) //"ARC "
4 - Version - Int16
8 - FileCount - Int16

Files:
0 - FileName - Chars(64)
64 - Unknown - Int32 //Not important, some sort of flag
68 - CompressedSize - Int32
72 - DecompressedSize - Int32
76 - Offset - Int32

Using zlib is beyond my limited coding capabilites. how would I go about unpacking them?

[Vash]

i don't think the files are zlibeed

maybe RPGviewer will work if you select DMC4

There is already a Resident Evil 5 ARC extractor avaliable right here on the forums, also if you want to OPEN and extrac for example ONLY textures (which are augo converted to DSS files) then id recommend using the resident evil 4 arc tool, as its been updated to support RE5 aswell.

If you check out the RE5 topic on this forum then it lists a website somewhere with a link to the program your looking for.

Has anyone been able to extract the files from Dead Rising, Lost Planet or Devil May Cry 4 on 360? Did those use the same compression too?

This is about the 360 version, not the PC version. As far as I know, no one has figured out how to decompress the ARCs on 360.

i am talking about the 360 files not the pc files.

yes, However we are still working on that. We plan to find a way to extract the Xbox 360 arc files to gain access to the new DLC coming to the Consoles.

If it would help, here's an arc file from PC and 360. I assume they contain the same data:

Xbox 360 files using lzx, I'm grabing then from my hdd right now, will make an app for it later.

Good to hear! Looking forward to see that utility.

A little bump here...

I'm just curious, how did the extraction go? Were you able to extract the archive files, and make an app for it?

Completly forgot about this. I need to come up with a way to decompress lzx files. If anyone has suggestions for a library that does this please let me know.
