I've unpacked Time Hollow and found out that almost everything is packed in .arc-files (archives). I'm wondering if it exists any tools to extract the files from the archive, or if it at least exists somekind of reference/documentation? Now, before you say "Use NARCTool" I would like to say that this kind of .arc-format isn't the same as the other .arc-format for DS. I've tried to use NARCTool, but without any luck. I've also tried to use some tools made for the GC/Wii .arc-format, but (as I excepted) they didn't work either. Well, if there's no reference/documentation nor tools to extract the archive, please help me find out how to extract this kind of .arc-files. I've already "researched" a little by myself. This is what I've come up with so far: Reference/Documentation (Not complete and not sure that it's correct): Code: OffsetÂÂÂÂÂÂÂÂSize ÂÂÂÂDescription 0x00000000ÂÂÂÂ0x4ÂÂÂÂÂÂÂÂ"Magic ID"ÂÂÂÂÂÂÂÂ// Always "ARCH" 0x00000004ÂÂÂÂ0x4ÂÂÂÂÂÂÂÂNo. of Files 0x00000008ÂÂÂÂ0x4ÂÂÂÂÂÂÂÂName Table Offset 0x0000000cÂÂÂÂ0x4ÂÂÂÂÂÂÂÂINFO-OffsetÂÂÂÂ// Not sure if this is part is called INFO, but that's what I call it for now 0x00000010ÂÂÂÂ0x4ÂÂÂÂÂÂÂÂFILE-OffsetÂÂÂÂ 0x00000014ÂÂÂÂ0x4ÂÂÂÂÂÂÂÂHEADER-size (in bytes) 0x00000020ÂÂÂÂ0x4ÂÂÂÂÂÂÂÂFile size (?) 0x00000024ÂÂÂÂ0x4ÂÂÂÂÂÂÂÂNo. of Files (again?) And here is a small dump from the program I made to read the .arc-files: Code: D00_00_00.arcÂÂÂÂ // Found in data\bg\digging ARCH 11 32 208 384 432 176 11 // This is NOT in Hex You can find the .arc-files in Time Hollow. Almost everything is in .arc-archives. All help is appreciated! Thanks in advance! [EDIT] Updated the "reference". Please help me complete it! [EDIT 2] Thanks to Barubary for his help finding out everything about the format!
