Choose archive extension:
Contents
CAT
- Format Type : Archive
- Endian Order : Little Endian
Format Specifications
// Archive Header
- uint32 {4} - Number Of Files
- // for each file
- uint32 {4} - File Hash
- uint32 {4} - File Offset
- uint32 {4} - File Length
Notes and Comments
- The files in the directory are NOT in the same order as the files in the archive. ie. file 1 in the directory may actually be file 3827 in the archive, etc. Actually, all records sorted in ascending order of File Hash value.
- Hash routine in C++ code for Magic: The Gathering:
unsigned int mtg_hash(char *s){
unsigned int hash;
unsigned int part[2];
unsigned int k;
hash = (s[0] ^ s[1]) << 24;
part[0] = 0;
part[1] = 0;
k = 3;
while(s[0]){
part[k&1] = part[k&1] + (tolower(s[0])*k);
k++;
s++;
}
hash = ((part[0] * part[1]) & 0xffffff) | hash;
return(hash);
}
Note that names inside CAT from MtG can be brute forced by template:
yyyyz.wvl
where:
yyyy - number from 0000 till 9999
z - one of the character from list: 'abcdeftx'
This last character (z) may or may not exists, so first you should try all names from '0000.wvl' till '9999.wvl' and only if none of them match try '0000a.wvl' - '9999a.wvl', '0000b.wvl' - '9999b.wvl' and so on.
