Kokeshi is a framework for injecting custom code into Pack Project titles. It is powered by the Kamek tool which loads and dynamically links code at runtime.

Kokeshi supports the following games:

*Revisions of Wii Sports Resort only include minor asset changes. The DOL remains unchanged.*

Support for Wii Music and Wii Fit, as well as other revisions of supported games are currently out of scope of this project. All Pack Project titles were stripped of debugging information, and require considerable effort to identify function symbols.

1. Install GNU make. If you have DevKitPRO or Windows Subsystem for Linux you may already have the tool installed.
2. Download the latest release of the PackProject fork of Kamek.
   1. Install the contents of the zip file to the tools/ directory.
3. Download the Wii v1.7 version of the CodeWarrior compiler.
   1. Install the contents of the Wii/1.7/ folder to the tools/ directory.

1. For each game that you want to build for, extract its filesystem using Dolphin Emulator.

   1. This can be done by right-clicking the game and selecting Properties > Filesystem > Disc > Extract Entire Disc...
   2. When prompted by Dolphin, select the directory corresponding to the game:

      Name	Path
      Wii Sports	romfs/sports
      Wii Play	romfs/play
      Wii Sports Resort	romfs/resort

   3. If done correctly, this will create a DATA folder in the corresponding romfs game folder.

2. For each game that you want to build for, copy DATA/sys/main.dol from its romfs folder to the base/ directory:

   Name	Path
   Wii Sports	base/baserom_sports.dol
   Wii Play	base/baserom_play.dol
   Wii Sports Resort	base/baserom_resort.dol

The Makefile provides various options for your project. You can choose which games to build your mod for by modifying the PACK variable. You can even write multiple names to build for multiple games!

To build your mod, simply run make from the project root directory. A make clean target is also provided to delete the contents of the build/ directory.

The default build target is the debug configuration. To disable debug features such as logging/assertions, run make with NDEBUG=1.

The patched DOL and your code modules are output in the build/ directory, and are also automatically installed into the romfs folder(s) for ease of testing.

One or more of the base DOL files are either in the wrong place or are currently open by another program. See the "Build Instructions" section if you are unusure where the files should go.

One or more of the base DOL files have the wrong SHA1 hash. This means that they are likely an unsupported game revision. See the "Supported Games" section if you are unusure which revisions are supported.

There was a problem building the Kamek loader. If you did not touch the loader code (in the loader/ directory), this may be a problem with Kokeshi.

It is also possible that you have the wrong version of CodeWarrior/Kamek or are missing one of these tools entirely.

An error occurred in the compiler. This is likely a result of your code, but could be a problem with Kokeshi. Make sure to read the compiler error to understand exactly where the problem is.

An error occurred in the Kamek linker. Based on the exception it spits out, you can determine what is happening:

You have more than one Kamek hook placed at the same address. This is not possible for the linker as they would overwrite each other's contents.

Kokeshi does not install many hooks itself, but it is possible you may be conflicting with libkiwi. Please search the repository for the address you are trying to hook, and see if there are conflicts.

You are referencing a symbol in the base game but the linker cannot resolve its address. This means it is missing from the symbol map(s) in the base/ directory.

Kamek will give you the mangled symbol name (i.e. calc__10RPSysSceneFv), which can be placed into the symbol map corresponding to your game with the following syntax: {name}=0x{address}.

This is very common because these symbol maps are created by hand and manually updated as more of the code is documented and understood.

If you add many symbols for your mod please consider making a pull request to Kokeshi to add these symbols for everyone else. :)

One or more of the base game filesystems were not extracted correctly. In the romfs folder for your game(s), the following directories must exist:

├── DATA: Disc partition root
│    └── sys: Disc header, DOL executable
│    └── files: Disc filesystem

See the "Build Instructions" section if you are unusure how to extract the game(s) correctly.
