AGB開発環境の構築（WSL・C++の場合）

ツールチェインをインストール：
- https://devkitpro.org/wiki/Getting_Started
- wget https://apt.devkitpro.org/install-devkitpro-pacman
- sudo dkp-pacman -S gba-dev
- sudo dkp-pacman -Syu
- sudo apt install mgba-qt
CMakeプロジェクトを作る：
- https://felixjones.co.uk/mgba_gdb/vscode.html
- https://github.com/felixjones/gba-toolchainをgit cloneする
- VSCodeのsettings.jsonでcmake.configureSettingsに"CMAKE_TOOLCHAIN_FILE": "./gba-toolchain/cmake/gba.toolchain.cmake" を追加
CMakeLists.txtを書く
- gba-toolchainのおかげで、主要なライブラリでfind_packageが使える

cmake_minimum_required(VERSION 3.18)

project(agb)

find_package(librom REQUIRED)
find_package(agbabi REQUIRED)
find_package(gba-hpp REQUIRED)

add_executable(agb
    src/main.cpp
)

target_compile_options(agb PRIVATE -mthumb -fconserve-stack -fomit-frame-pointer)
target_link_libraries(agb PRIVATE librom agbabi gba-hpp)
    
set_target_properties(agb PROPERTIES
    ROM_TITLE "agb"
    ROM_ID 0000
    ROM_MAKER 00
    ROM_VERSION 0
)

install_rom(agb)

VSCodeのlaunch.jsonでmGBAを起動するタスクを書く：

    "configurations": [
        {
            "name": "(gdb) launch",
            "type": "cppdbg",
            "request": "launch",
            "targetArchitecture": "arm",
            "program": "${command:cmake.launchTargetPath}",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerServerAddress": "localhost:2345",
            "miDebuggerPath": "${env:DEVKITARM}/bin/arm-none-eabi-gdb",
            "setupCommands": [
                {
                    "text": "shell \"mgba-qt\" -g \"${command:cmake.launchTargetPath}\" &"
                }
            ]
        },
    ]
