dlc-wad-splitter

Splits full Wii DLC WAD packages into smaller WADs, suitable for DLC tools. Heavily based on wad2bin.

Usage:

dlc-wad-splitter v0.1 (c) DarkMatterCore.
Built: 17:41:19 Jul 14 2020.

Usage: dlc-wad-splitter <input WAD> <output dir> <content count per split DLC>

Paths must not exceed 259 characters. Relative paths are supported.
The input WAD package must hold a TMD with a valid signature, as well as all the contents referenced
in the content records section from the TMD. If a single content is missing or has a wrong hash, the
process will be stopped.
Furthermore, the total content count minus 1 must be a multiple of the provided content count.
Output split DLC WADs will hold content #0 + "content count" contents.

Building instructions:

• Windows (should you really bother? 32-bit binaries are provided):

  1. A collection of Unix/Linux utilities such as make, mkdir, rm, ar and cp, as well as a gnu11 standard compliant C compiler, are needed to build this project. There are a few ways to achieve this under Windows:
     • Install TDM-GCC and devkitPro + MSYS2, or...
     • Install MinGW + MSYS, or...
     • (Untested) Under Windows 10:
       • Install the Windows Subsystem for Linux (WSL) distribution of your preference (I'll assume you chose Ubuntu).
       • Install the gcc package by using the sudo apt update and sudo apt install gcc commands.
       • Modify the Makefiles to use wsl.exe before each Unix command call.
     • Regardless of the option you end up choosing, please make sure your PATH environment variable has been properly updated!
  2. Create a copy of config.mk.template in the same directory and rename it to config.mk.
  3. Build using the make command.

• Unix-like OS (Linux / MacOS):

  1. Install your preferred C compiler compatible with the gnu11 standard using your OS's package manager (e.g. apt, pacman, brew, etc.).
  2. Create a copy of config.mk.template in the same directory and rename it to config.mk. Open it with a text editor.
  3. Update the CC variable to make it point to your installed C compiler (leaving gcc is usually fine), and wipe the value from the EXE_EXT variable.
  4. Build using the make command.

Supported DLCs:

Not all DLCs can be splitted - this is because not all games are capable of loading only a subset of the content files from their DLCs. For this purpose, dlc-wad-splitter holds a hardcoded DLC title ID list, in order to avoid splitting a DLC WAD that simply won't work.

Only the following DLCs are supported:
