This project is work in progress and far from complete.

t2fs.h is the core of this project, it is responsible for navigating the data tree, decompression and deinterleaving.

To get some use out of the data that can be accessed with t2fs.h we provide some higher level APIs in models/*.h

Gettings started

Core basics

#include "t2fs.h"
 
int main() {
  t_t2fs lib;
  const char *filepath = "/home/user/games/Seeds of Evil.lss";
  t2fs_init(&lib);
 
  // Auto detect needed config for the given input file based
  // on the filename. This to handle endianness and other
  // differences between files.
  if (t2fs_config_auto_detect(&lib.config, filepath) != 0) {
    return 1;
  }
 
  if (t2fs_open(&lib, filepath, NULL, 1) != T2FS_OK) {
    // error .. do not use the lib object after this, calling t2fs_close()
    // would be ok as long as it's inited.
    return 1;
  }
 
  // do stuff
  // ..
 
  // free all nodes, their data and close the file.
  t2fs_close(&lib);
 
  return 0;
}

Also initial work has been done on writing the schema for the data of N64 Rage Wars and N64 Shadow of Oblivion, extracted from N64 roms. Textures are already working, they have the same data structs, the rest still needs to be looked into.
