Luigi's Mansion 2 Research Thread

Code:

class dict

{

    const uint magic = 0xA9F32458; //0x0, seems like file signature(though knowing this game this is probably just another constant or something), always "X$ó©" in ASCII(maybe be different depending on your system codepage, since it uses values outside the "basic latin" portion of ASCII)

    const byte unk = 0x4; //0x4

    const byte unk2 = 0x1; //0x5

    byte isCompressed; //0x6, compression flag, 0x0 - uncompressed, 0x1 - ZLib

    const byte unk3 = 0x0; //0x7

    uint fileCount; //0x8, file count(this includes file entries which refer to duplicate(like usually the second entry in the file is always a dupe of the first one, refers to the same data location, sometimes with a slightly different length) or empty files)

    uint largestCompressedFile; //0xC, seems to be size of the largest file in compressed form, always null if no compression is used

    const ushort unk6 = 0x0; //0xE

    ushort unk7; //0x10, seems to be similar in many files



    //[0x12:0x2B] is const for (probably) all dict files, so I'll just dump the raw bytes here

    //02 02 90 25 BD 78 02 03 04 05 00 00 00 00 66 7C F5 04 01 02 03 04 00 00 05 06



    byte[fileCount] unk8; //0x2C, some sorta table, length in bytes always matches fileCount



    fileTableEntry[fileCount] fileTable; //0x2C+fileCount, contains info about files in the data, see struct below for more info



    const string data = ".data\0"; //0x2C+fileCount*0x11, in ASCII

    const string debug = ".debug\0"; //0x2C+fileCount*0x11+0x6, in ASCII

    //EOF

}



class FileTableEntry

{

    uint startOffset; //0x0, offset at which the file starts in the data

    uint decompressedLength; //0x4, file length after decompression(present whether the data is compressed or not, so for data without compression this is the file size)

    uint compressedLength; //0x8, file length in compressed form(only present if compression is used, other wise equals null)

    byte[4] unk; //0xC, probably file attributes

}

Code:

const size = 0x38; //Not actually in the data, just a constant



uint magic; //0x0, Always PÓwé(unless your windows codepage is different, then you can expect many other variations of this)

uint id;  //0x4, texture id, unique for each texture in most cases(though some identical textures in different archives have the same id)

uint unk2; //0x8, is always the same between textures with equal dimentions and texture format

uint idCopy; //0xC, seems to be a copy of id

ushort width; //0x18, texture width

ushort height; //0x1A, texture height

byte mipLevel; //0x1F, unsure which encoding this uses, stored as mipmap_levels*11 for some odd reason

byte texFmt; //0x38, mostly gonna be 0xC for ETC1 and 0xD for ETC1A4, these values are the same as in SDK enums



//Everything else is mostly 0x0 with some exceptions, but I have no idea what those values do as they seem to be the same between most files
