已知其他类 Unix 平台(如 OpenBSD)也可以使用,但未经测试且不完全受支持。

系统需求

系统需求很低。任何可以运行 Windows Vista 或更高版本的计算机都应该能够处理模拟机制,还需要支持 OpenGL 1.1 或更高版本。而对于着色器和高级功能,则需要支持 OpenGL 3.2 或更高版本。

下载

可在官方网站的下载(Downloads)区域找到下载地址。可在 GitHub 找到源代码。

控制键位

可在设置菜单中进行控制键位的配置。许多游戏控制器应该会在默认情况下自动映射。键盘的默认控制键位如下:

  • A:X
  • B:Z
  • L:A
  • R:S
  • Start:回车键
  • Select:退格键

编译

编译需要使用 CMake 3.1 或更新版本。已知 GCC 和 Clang 都可以编译 mGBA,而 Visual Studio 2013 和更旧的版本则无法编译。我们即将实现对 Visual Studio 2015 或更新版本的支持。

Docker 构建

对于大多数平台来说,建议使用 Docker 进行构建。我们提供了多个 Docker 映像,其中包含在多个平台上构建 mGBA 所需的工具链和依赖项。

要使用 Docker 映像构建 mGBA,只需在 mGBA 的签出(checkout)根目录中运行以下命令:

docker run --rm -t -v $PWD:/home/mgba/src mgba/windows:w32

此命令将生成 build-win32 目录。将 mgba/windows:w32 替换为其他平台上的 Docker 映像,会生成相应的其他目录。Docker Hub 上提供了以下 Docker 映像:

  • mgba/3ds
  • mgba/switch
  • mgba/ubuntu:xenial
  • mgba/ubuntu:bionic
  • mgba/ubuntu:focal
  • mgba/ubuntu:groovy
  • mgba/vita
  • mgba/wii
  • mgba/windows:w32
  • mgba/windows:w64

*nix 构建

要在基于 Unix 的系统上使用 CMake 进行构建,推荐执行以下命令:

mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr ..
make
sudo make install

这些命令将构建 mGBA 并将其安装到 /usr/bin/usr/lib 中。系统会自动检测已安装的依赖项,如果未找到依赖项,则会在提示找不到依赖项的情况下运行 cmake 命令,并显示已被禁用的功能。

如果您使用的是 MacOS,则步骤略有不同。假设您使用的是自制软件包管理器,建议使用以下命令来获取依赖项并进行构建:

brew install cmake ffmpeg libzip qt5 sdl2 libedit pkg-config
mkdir build
cd build
cmake -DCMAKE_PREFIX_PATH=`brew --prefix qt5` ..
make

请注意,您不能在 MacOS 上执行 make install,因为此命令不能正常工作。

Windows 开发者构建

MSYS2

如果要在 Windows 上进行构建,建议使用 MSYS2。请按照 MSYS2 网站上的安装步骤操作。请确保您运行的是 32 位版本的 MSYS2(“MSYS2 MinGW 32-bit”)。如果想要构建 x86_64 版本,则运行 64 位版本的 MSYS2(“MSYS2 MinGW 64-bit”) ,并执行以下额外命令(包括花括号)来安装所需的依赖项(请注意,此命令涉及下载超过 1100MiB 的包,因此会需要很长一段时间):

pacman -Sy --needed base-devel git ${MINGW_PACKAGE_PREFIX}-{cmake,ffmpeg,gcc,gdb,libelf,libepoxy,libzip,pkgconf,qt5,SDL2,ntldd-git}

运行以下命令检查源代码:

git clone https://github.com/mgba-emu/mgba.git

最后运行以下命令进行构建:

mkdir -p mgba/build
cd mgba/build
cmake .. -G "MSYS Makefiles"
make -j$(nproc --ignore=1)

请注意,此版本的 mGBA for Windows 不适合分发,因为运行此版本所需的 DLL 非常分散,但非常适合开发。但是,如果需要分发此类版本(例如用于在未安装 MSYS2 环境的计算机上进行测试),请运行 cpack-G ZIP,准备一个包含所有必要 DLL 的压缩文件。

Visual Studio

使用 Visual Studio 进行构建需要同样复杂的设置。首先需要安装 vcpkg。安装 vcpkg 后,还需要安装数个额外的软件包:

vcpkg install ffmpeg[vpx,x264] libepoxy libpng libzip sdl2 sqlite3

请注意,此安装将不支持 Nvidia 硬件上的硬件加速视频编码。如果对此非常在意,则需要预先安装 CUDA,然后用 ffmpeg[vpx,x264,nvcodec] 替换前面命令中的 ffmpeg[vpx,x264]

您还需要安装 Qt。但不幸的是,由于 Qt 已被一家境况不佳的公司而不是合理的组织所拥有并运营,所以不再存在针对最新版本的离线开源版本安装程序,需要退回到旧版本的安装程序 (会要求创建一个原本已无用的帐号,但可以通过临时设置无效代理或以其他方式禁用网络来绕过这一机制。)、使用在线安装程序(无论如何都需要一个帐号),或使用 vcpkg 进行构建(速度很慢)。这些都不是很好的选择。需要针对安装程序安装适用的 MSVC 版本。请注意,离线安装程序不支持 MSVC 2019。若使用 vcpkg,您需要花费相当一段时间将其安装,尤其是在四核或更少内核的计算机上花费时间更久:

vcpkg install qt5-base qt5-multimedia

下一步打开 Visual Studio,选择“克隆仓库”, 输入 https://github.com/mgba-emu/mgba.git。在 Visual Studio 完成克隆后,转到“文件”>“CMake”,然后打开已签出(checked out)仓库的 CMakeLists.txt 文件。在此基础上便可像其他 Visual Studio CMake 项目一样在 Visual Studio 中开发 mGBA。

工具链构建

如果您拥有 devkitARM(3DS)、devkitPPC(Wii)、devkitA64(Switch)或 vitasdk(PS Vita),您可以使用以下命令进行构建:

mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=../src/platform/3ds/CMakeToolchain.txt ..
make

-DCMAKE_TOOLCHAIN_FILE 参数替换为以下不同平台的参数:

  • 3DS:../src/platform/3ds/CMakeToolchain.txt
  • Switch:../src/platform/switch/CMakeToolchain.txt
  • Vita:../src/platform/psp2/CMakeToolchain.vitasdk
  • Wii:../src/platform/wii/CMakeToolchain.txt

依赖项

mGBA 没有硬性的依赖项,但是特定功能需要以下可选的依赖项。如果找不到依赖项,则这些可选功能将会被禁用。

  • Qt 5:GUI 前端的所需依赖项。音频需要 Qt Multimedia 或 SDL。
  • SDL:更基本的前端以及在 Qt 前端中支持游戏手柄的所需依赖项。推荐使用 SDL 2、但也支持 1.2。
  • zlib 和 libpng:截图与 PNG 即时存档支持的所需依赖项
  • libedit:命令行调试器的所需依赖项
  • ffmpeg 或 libav:录制视频、GIF、WebP 和 APNG 的所需依赖项
  • libzip 或 zlib:载入储存在 ZIP 文件中的 ROM 的所需依赖项。
  • SQLite3:游戏数据库的所需依赖项
  • libelf:ELF 载入的所需依赖项

SQLite3、libpng 以及 zlib 已包含在模拟器中,因此不需要先对这些依赖项进行外部编译。

Footnotes

[1] 目前缺失的功能有

  • 模式 3、4 和 5 的 OBJ 窗口 (Bug #5)

[2] 闪存大小检测在某些情况下不起作用。 这些可以在运行时中进行配置,但如果遇到此类情况,建议提交错误。

[3] 仅 Qt 端口需要 10.9。应该可以在 10.7 或更早版本上构建或运行 Qt 端口,但这类操作不受官方支持。已知 SDL 端口可以在 10.5 上运行,并且可能能够在旧版本上运行。

License Grants and Conditions -------------------------------- 2.1. Grants Each Contributor hereby grants You a world-wide, royalty-free, non-exclusive license: (a) under intellectual property rights (other than patent or trademark) Licensable by such Contributor to use, reproduce, make available, modify, display, perform, distribute, and otherwise exploit its Contributions, either on an unmodified basis, with Modifications, or as part of a Larger Work; and (b) under Patent Claims of such Contributor to make, use, sell, offer for sale, have made, import, and otherwise transfer either its Contributions or its Contributor Version. 2.2. Effective Date The licenses granted in Section 2.1 with respect to any Contribution become effective for each Contribution on the date the Contributor first distributes such Contribution. 2.3. Limitations on Grant Scope The licenses granted in this Section 2 are the only rights granted under this License. No additional rights or licenses will be implied from the distribution or licensing of Covered Software under this License. Notwithstanding Section 2.1(b) above, no patent license is granted by a Contributor: (a) for any code that a Contributor has removed from Covered Software; or (b) for infringements caused by: (i) Your and any other third party's modifications of Covered Software, or (ii) the combination of its Contributions with other software (except as part of its Contributor Version); or (c) under Patent Claims infringed by Covered Software in the absence of its Contributions. This License does not grant any rights in the trademarks, service marks, or logos of any Contributor (except as may be necessary to comply with the notice requirements in Section 3.4). 2.4. Subsequent Licenses No Contributor makes additional grants as a result of Your choice to distribute the Covered Software under a subsequent version of this License (see Section 10.2) or under the terms of a Secondary License (if permitted under the terms of Section 3.3). 2.5. Representation Each Contributor represents that the Contributor believes its Contributions are its original creation(s) or it has sufficient rights to grant the rights to its Contributions conveyed by this License. 2.6. Fair Use This License is not intended to limit any rights You have under applicable copyright doctrines of fair use, fair dealing, or other equivalents. 2.7. Conditions Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in Section 2.1. 3. Responsibilities ------------------- 3.1. Distribution of Source Form All distribution of Covered Software in Source Code Form, including any Modifications that You create or to which You contribute, must be under the terms of this License. You must inform recipients that the Source Code Form of the Covered Software is governed by the terms of this License, and how they can obtain a copy of this License. You may not attempt to alter or restrict the recipients' rights in the Source Code Form. 3.2. Distribution of Executable Form If You distribute Covered Software in Executable Form then: (a) such Covered Software must also be made available in Source Code Form, as described in Section 3.1, and You must inform recipients of the Executable Form how they can obtain a copy of such Source Code Form by reasonable means in a timely manner, at a charge no more than the cost of distribution to the recipient; and (b) You may distribute such Executable Form under the terms of this License, or sublicense it under different terms, provided that the license for the Executable Form does not attempt to limit or alter the recipients' rights in the Source Code Form under this License. 3.3. Distribution of a Larger Work You may create and distribute a Larger Work under terms of Your choice, provided that You also comply with the requirements of this License for the Covered Software. If the Larger Work is a combination of Covered Software with a work governed by one or more Secondary Licenses, and the Covered Software is not Incompatible With Secondary Licenses, this License permits You to additionally distribute such Covered Software under the terms of such Secondary License(s), so that the recipient of the Larger Work may, at their option, further distribute the Covered Software under the terms of either this License or such Secondary License(s). 3.4. Notices You may not remove or alter the substance of any license notices (including copyright notices, patent notices, disclaimers of warranty, or limitations of liability) contained within the Source Code Form of the Covered Software, except that You may alter any license notices to the extent required to remedy known factual inaccuracies. 3.5. Application of Additional Terms You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Software. However, You may do so only on Your own behalf, and not on behalf of any Contributor. You must make it absolutely clear that any such warranty, support, indemnity, or liability obligation is offered by You alone, and You hereby agree to indemnify every Contributor for any liability incurred by such Contributor as a result of warranty, support, indemnity or liability terms You offer. You may include additional disclaimers of warranty and limitations of liability specific to any jurisdiction. 4. Inability to Comply Due to Statute or Regulation --------------------------------------------------- If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Software due to statute, judicial order, or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be placed in a text file included with all distributions of the Covered Software under this License. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it. 5. Termination -------------- 5.1. The rights granted under this License will terminate automatically if You fail to comply with any of its terms. However, if You become compliant, then the rights granted under this License from a particular Contributor are reinstated (a) provisionally, unless and until such Contributor explicitly and finally terminates Your grants, and (b) on an ongoing basis, if such Contributor fails to notify You of the non-compliance by some reasonable means prior to 60 days after You have come back into compliance. Moreover, Your grants from a particular Contributor are reinstated on an ongoing basis if such Contributor notifies You of the non-compliance by some reasonable means, this is the first time You have received notice of non-compliance with this License from such Contributor, and You become compliant prior to 30 days after Your receipt of the notice. 5.2. If You initiate litigation against any entity by asserting a patent infringement claim (excluding declaratory judgment actions, counter-claims, and cross-claims) alleging that a Contributor Version directly or indirectly infringes any patent, then the rights granted to You by any and all Contributors for the Covered Software under Section 2.1 of this License shall terminate. 5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user license agreements (excluding distributors and resellers) which have been validly granted by You or Your distributors under this License prior to termination shall survive termination. ************************************************************************ * * * 6. Disclaimer of Warranty * * ------------------------- * * * * Covered Software is provided under this License on an "as is" * * basis, without warranty of any kind, either expressed, implied, or * * statutory, including, without limitation, warranties that the * * Covered Software is free of defects, merchantable, fit for a * * particular purpose or non-infringing. The entire risk as to the * * quality and performance of the Covered Software is with You. * * Should any Covered Software prove defective in any respect, You * * (not any Contributor) assume the cost of any necessary servicing, * * repair, or correction. This disclaimer of warranty constitutes an * * essential part of this License. No use of any Covered Software is * * authorized under this License except under this disclaimer. * * * ************************************************************************ ************************************************************************ * * * 7. Limitation of Liability * * -------------------------- * * * * Under no circumstances and under no legal theory, whether tort * * (including negligence), contract, or otherwise, shall any * * Contributor, or anyone who distributes Covered Software as * * permitted above, be liable to You for any direct, indirect, * * special, incidental, or consequential damages of any character * * including, without limitation, damages for lost profits, loss of * * goodwill, work stoppage, computer failure or malfunction, or any * * and all other commercial damages or losses, even if such party * * shall have been informed of the possibility of such damages. This * * limitation of liability shall not apply to liability for death or * * personal injury resulting from such party's negligence to the * * extent applicable law prohibits such limitation. Some * * jurisdictions do not allow the exclusion or limitation of * * incidental or consequential damages, so this exclusion and * * limitation may not apply to You. * * * ************************************************************************ 8. Litigation ------------- Any litigation relating to this License may be brought only in the courts of a jurisdiction where the defendant maintains its principal place of business and such litigation shall be governed by laws of that jurisdiction, without reference to its conflict-of-law provisions. Nothing in this Section shall prevent a party's ability to bring cross-claims or counter-claims. 9. Miscellaneous ---------------- This License represents the complete agreement concerning the subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. Any law or regulation which provides that the language of a contract shall be construed against the drafter shall not be used to construe this License against a Contributor. 10. Versions of the License --------------------------- 10.1. New Versions Mozilla Foundation is the license steward. Except as provided in Section 10.3, no one other than the license steward has the right to modify or publish new versions of this License. Each version will be given a distinguishing version number. 10.2. Effect of New Versions You may distribute the Covered Software under the terms of the version of the License under which You originally received the Covered Software, or under the terms of any subsequent version published by the license steward. 10.3. Modified Versions If you create software not governed by this License, and you want to create a new license for such software, you may create and use a modified version of this License if you rename the license and remove any references to the name of the license steward (except to note that such modified license differs from this License). 10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses If You choose to distribute Source Code Form that is Incompatible With Secondary Licenses under the terms of this version of the License, the notice described in Exhibit B of this License must be attached. Exhibit A - Source Code Form License Notice ------------------------------------------- This Source Code Form is subject to the terms of the Mozilla Public License, v. 2.0. If a copy of the MPL was not distributed with this file, You can obtain one at http://mozilla.org/MPL/2.0/. If it is not possible or desirable to put the notice in a particular file, then You may include the notice in a location (such as a LICENSE file in a relevant directory) where a recipient would be likely to look for such a notice. You may add additional accurate notices of copyright ownership. Exhibit B - "Incompatible With Secondary Licenses" Notice --------------------------------------------------------- This Source Code Form is "Incompatible With Secondary Licenses", as defined by the Mozilla Public License, v. 2.0.
