Kameo: RePowered

Static recompilation of Kameo: Elements of Power (Xbox 360) for Windows and Linux, built on the ReXGlue SDK.

This project converts the Xbox 360 PowerPC default.xex into native x86_64 code at build time, then wraps it with a small host runtime (logging, overlays, hooks) so the game runs natively and can be modded like a PC port.

You must own the game. This project does not ship any Kameo code, data, or assets. You provide your own legally dumped kameo.iso.

Using a pre-built release

Kameo: RePowered is available on Goopie!

Get the latest stable build here.

Nightly builds are available here.

Just place the downloaded executable next to the extracted assets directory and run it.

Building from scratch

0. Install dependencies

Linux (Arch/CachyOS)

paru -S clang20 cmake ninja vulkan-headers extract-xiso

Windows

scoop install llvm cmake ninja

1. Clone

git clone https://github.com/birabittoh/KameoRePowered.git
cd KameoRePowered

2. Download the ReXGlue SDK

python scripts/download-sdk.py

This downloads the latest nightly and installs it into sdk/<platform>/.

3. Provide your game

Extract your legally dumped ISO directly into assets/:

extract-xiso -d assets "Kameo - Elements of Power (USA).iso"

4. Build

Use this script:

# Vanilla
python scripts/build.py

# Title Update
python scripts/build.py --tu /path/to/TU_*

5. DLC (optional)

Place your DLC content packages (STFS files) into the emulator save-data directory and run the extraction script:

# Linux
mkdir -p ~/.local/share/kameorepowered/0000000000000000/4D5307D2/00000002/
cp /path/to/dlc/* ~/.local/share/kameorepowered/0000000000000000/4D5307D2/00000002/

# Windows
mkdir "%USERPROFILE%\Documents\kameorepowered\0000000000000000\4D5307D2\00000002"
copy C:\path\to\dlc\* "%USERPROFILE%\Documents\kameorepowered\0000000000000000\4D5307D2\00000002"

# Then extract
python scripts/extract_dlc.py

This replaces each raw STFS package with a directory of extracted files and generates the .header files needed for the game to detect and unlock the DLC.

6. Run

python scripts/run.py

The run script sets up the library path, GPU offload variables, and passes --game_data_root and --update_data_root (if a TU build extracted update data) automatically.

Options

Options can be persisted by adding them to kameorepowered.toml next to the game executable, for example:

vulkan_device = 1 # NVIDIA GPU
user_language = 4 # French

Keyboard & mouse

Keyboard and mouse controls are enabled by default. Default mapping:

Input	Xbox 360 button
WASD	Left stick
Mouse	Right stick (camera)
1 / 2 / 3	X / Y / B
Space	A
Left click	LT
Right click	RT
Q / E	LB / RB
Enter	Start
Backspace	Back
Arrow keys	D-Pad

All bindings are overridable via kameorepowered.toml (or CLI flags). For example:

keybind_a = "F"
keybind_left_trigger = "LControl"
mnk_sensitivity = 0.5

Mouse sensitivity is controlled by mnk_sensitivity (default 1.0).

Language selection

The game defaults to English. Pass --user_language <id> to switch:

ID	Language
1	English
2	Japanese
3	German
4	French
5	Spanish
6	Italian
7	Korean

./kameorepowered --user_language 6

GPU selection

If you have multiple GPUs, you can force a specific one:

./kameorepowered --vulkan_device 1

List available devices by running the game without the flag.

Logging

The game writes logs into the logs directory by default, but you can configure it.

./kameorepowered --log_file kameo.log --log_level debug

Adding a hook

1. Find the guest address in default.xex.

2. Add to kameorepowered_config.toml:

   [functions]
   0x8XXXXXXX = {name = "MyFunction"}
   

3. Implement in src/kameorepowered_hooks.cpp:

   void MyFunction(PPCContext& ctx, uint8_t* base) {
       // your logic
   }
   

4. Re-run codegen and rebuild.

Adding a midasm hook (inline patch)

[[midasm_hook]]
address = 0x8XXXXXXX
name = "MyHook"
registers = ["r3"]
return = true

Implement in src/kameorepowered_hooks.cpp:

void MyHook(PPCRegister& r3) {
    r3.u32 = 1;
}
