## Build instructions:
First clone the repository: `git clone --recursive https://github.com/SimoneN64/Kaizen`

### Windows

This build uses Visual Studio with Vcpkg and Clang-cl

Dependencies:
- CMake 3.20 or higher
- SDL2 (install it by making sure that you're choosing the "vulkan" extension of the package and the x64-windows triplet: `vcpkg install sdl2[vulkan]:x64-windows`)
- fmtlib (install it by making sure that you're choosing the x64-windows triplet: `vcpkg install fmt:x64-windows`)
- nlohmann-json (install it by making sure that you're choosing the x64-windows triplet: `vcpkg install nlohmann-json:x64-windows`)

```
cd path/to/kaizen
mkdir build
cd build
cmake -T clangcl -DCMAKE_TOOLCHAIN_FILE=path/to/vcpkg/scripts/buildsystems/vcpkg.cmake -DCMAKE_BUILD_TYPE=Release -S ../src
cmake --build . --config Release
```

### Linux

Dependencies:
- GCC or Clang with C++17 support
- CMake 3.20 or higher
- SDL2
- fmtlib
- Vulkan API (including the validation layers) + SPIR-V tools
- nlohmann-json

```
cd path/to/kaizen
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -S ../src
cmake --build . --config Release
```

## Running:
```
./path/to/kaizen [ROM] [Mupen Movie]
```

Your GPU needs to support Vulkan 1.1+, because the RDP is implemented via [ParaLLEl-RDP](https://github.com/Themaister/parallel-rdp).

## Roadmap
- [x] Full R4300i emulation
- [x] Full RCP emulation
- [x] Full TLB emulation
- [x] Full joybus emulation (but it's not configurable by the user at the moment)
- [x] TAS replay (using Mupen's format)
- [ ] Qt or wxWidgets for native GUI (keeping ImGui as opt-in).
- [ ] JIT, with support for x86_64 and ARM (using an IR).
- [ ] Debug tools: disassembly, breakpoints, single-step and memory editor
- [ ] TAS tools: TAS input, recording (using Mupen's format), save-states, rewind and frame-advance
- [ ] Cheat support
- [ ] Allow to optionally pass a PIF image for the boot process (it's HLE'd at the moment)

This list will probably grow with time!
