在 openEuler 树莓派上打游戏！

说明

这个仓库里面的脚本，能让搭载 openEuler 21.03 的树莓派4上跑 Retropie。

Retropie 是一个复古游戏机，能跑很多以前游戏机的游戏，比如吃豆人啥的。

安装

首先，我移植了 140 多个 openEuler 没有的安装包，你需要等我把这些软件包提交到 openEuler 社区之后才能安装，或者我得想办法上传到哪里你能下载的地方。

其次，你需要安装必要的安装包：

sudo dnf update 
sudo dnf install git

由于国内访问 github 常常会报错，因此如果后续使用 https 协议报 git clone 错误，你需要做以下配置，使用 ssh 协议，来解决报错

sudo su 
git config --global url."git@github.com:".insteadOf https://github.com/

然后你就可以运行安装脚本了

cd
git clone --depth=1 git@github.com:apple-ouyang/RetroPie-Setup.git
cd RetroPie-Setup
git checkout openEuler
sudo ./retropie_setup.sh

然后蓝色的界面便会启动，一路确认后，点击 Basic Install，再一路确认，等待漫长的编译之后（大概需要一晚上），你就安装好了。

如果安装报错，请多装几次，或者在这里提 issue，我会尽量解决。

运行游戏

你可以参考我的运行游戏的视频，就在仓库里面的mp4视频，这里是链接：如何运行游戏 你得自己找到游戏，然后放到 ~/RetroPie/roms 的对应文件夹下，之后重启树莓派。

重启你便能进入 Retropie，初始时需要你进行一些键盘配置，来模拟手柄。 配置好后，你便能选择你刚刚放好的游戏，然后启动！

。。。

然后你就会发现黑屏，笑，暂时这里有一些bug，我没能解决，不过你还是可以玩儿游戏。

每次运行你选择的游戏，在黑屏之后，你需要按下F4，退出 Retropie，然后执行以下命令吗，来打印报错信息：

cat /dev/shm/runcommand.log

比如，我运行吃豆人游戏之后，按下 F4 退出，之后运行以上命令就有以下输出：

Parameters: 
Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-genesis-plus-gx/genesis_plus_gx_libretro.so --config /opt/retropie/configs/gamegear/retroarch.cfg "/home/ouyang/RetroPie/roms/gamegear/Pacman_(J).gg" --appendconfig /dev/shm/retroarch.cfg
/opt/retropie/supplementary/runcommand/runcommand.sh: line 1263: 21929 Segmentation fault      (core dumped) /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-genesis-plus-gx/genesis_plus_gx_libretro.so --config /opt/retropie/configs/gamegear/retroarch.cfg "/home/ouyang/RetroPie/roms/gamegear/Pacman_(J).gg" --appendconfig /dev/shm/retroarch.cfg

最后一步，你只需要运行 Executing 后面的命令，就能开始游戏了！ 比如：

/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-genesis-plus-gx/genesis_plus_gx_libretro.so --config /opt/retropie/configs/gamegear/retroarch.cfg "/home/ouyang/RetroPie/roms/gamegear/Pacman_(J).gg" --appendconfig /dev/shm/retroarch.cfg

RetroPie-Setup

General Usage

Shell script to setup the Raspberry Pi, Vero4K, ODroid-C1 or a PC running Ubuntu with many emulators and games, using EmulationStation as the graphical front end. Bootable pre-made images for the Raspberry Pi are available for those that want a ready-to-go system, downloadable from the releases section of GitHub or via our website at https://retropie.org.uk.

This script is designed for use on Raspberry Pi OS (previously called Raspbian) on the Raspberry Pi, OSMC on the Vero4K or Ubuntu on the ODroid-C1 or a PC.

To run the RetroPie Setup Script make sure that your APT repositories are up-to-date and that Git is installed:

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install git

Then you can download the latest RetroPie setup script with:

cd
git clone --depth=1 https://github.com/RetroPie/RetroPie-Setup.git

The script is executed with:

cd RetroPie-Setup
sudo ./retropie_setup.sh

When you first run the script it may install some additional packages that are needed.

Binaries and Sources

On the Raspberry Pi, RetroPie Setup offers the possibility to install from binaries or source. For other supported platforms only a source install is available. Installing from binary is recommended on a Raspberry Pi as building everything from source can take a long time.

For more information, visit the site at https://retropie.org.uk or the repository at https://github.com/RetroPie/RetroPie-Setup.

Docs

You can find useful information about several components and answers to frequently asked questions in the RetroPie Docs. If you think that there is something missing, you are invited to submit a pull request to the RetroPie-Docs repository.

Thanks

This script just simplifies the usage of the great works of many other people that enjoy the spirit of retrogaming. Many thanks go to them!
