EmulationStation
|
|
================
|
|
|
|
A cross-platform graphical front-end for emulators with controller navigation.
|
|
|
|
**Raspberry Pi users:**
|
|
A cool guy named petrockblog made a script which automatically installs many emulators and ES. It also includes options for configuring your RPi and setting it up to boot directly into ES. You can find it here: https://github.com/petrockblog/RetroPie-Setup
|
|
|
|
I found a bug! I have a problem!
|
|
================================
|
|
|
|
- First, try to check the [issue list](https://github.com/Aloshi/EmulationStation/issues?state=open) for some entries that might match your problem. Make sure to check closed issues too!
|
|
- If you're running EmulationStation on a on Raspberry Pi and have problems with config file changes not taking effect, content missing after editing, etc., check if your SD card is corrupted (see issues [#78](https://github.com/Aloshi/EmulationStation/issues/78) and [#107](https://github.com/Aloshi/EmulationStation/issues/107)). You can do this with free tools like [h2testw](http://www.heise.de/download/h2testw.html) or [F3](http://oss.digirati.com.br/f3/).
|
|
- Try to update to the latest version of EmulationStation using git (you might need to delete your `es_input.cfg` and `es_settings.cfg` after that to reset them to default values):
|
|
```
|
|
cd EmulationStation
|
|
git pull
|
|
export CXX=g++-4.7
|
|
cmake .
|
|
make
|
|
```
|
|
- If your problem still isn't gone, the best way to report a bug is to post an issue on GitHub. Try to post the simplest steps possible to reproduce the bug. Include files you think might be related (except for ROMs, of course). If you haven't re-run ES since the crash, the log file `~/.emulationstation/es_log.txt` is also helpful.
|
|
|
|
Building
|
|
========
|
|
|
|
EmulationStation uses some C++11 code, which means you'll need to install at least g++-4.7 on Linux, or VS2010 on Windows.
|
|
For installing and switching to g++-4.7 see [here](http://lektiondestages.blogspot.de/2013/05/installing-and-switching-gccg-versions.html). You can also just use `export CXX=g++-4.7` to explicitly specify the compiler for CMake (make sure you delete your CMake cache files if it's not working).
|
|
|
|
EmulationStation has a few dependencies. For building, you'll need SDL2, Boost.System, Boost.Filesystem, FreeImage, FreeType, and Eigen3. You'll also need the DejaVu TrueType font on Linux to run ES.
|
|
|
|
**On Linux:**
|
|
All of this be easily installed with apt-get:
|
|
```
|
|
sudo apt-get install libsdl2-dev libboost-system-dev libboost-filesystem-dev libfreeimage-dev libfreetype6-dev libeigen3-dev ttf-dejavu libasound2-dev
|
|
```
|
|
|
|
On "desktop" Linux (that is, *not* the Raspberry Pi), you'll also need OpenGL. Try installing the MESA development package with:
|
|
```
|
|
sudo apt-get libgl1-mesa-dev
|
|
```
|
|
|
|
On the Raspberry Pi, there are also a few special libraries, located in /opt/vc/: the Broadcom libraries, libEGL, and GLES. You shouldn't need to install them.
|
|
|
|
**Generate and Build Makefile with CMake:**
|
|
```
|
|
cd EmulationStation
|
|
export CXX=g++-4.7
|
|
cmake .
|
|
make
|
|
```
|
|
|
|
**On Windows:**
|
|
|
|
[Boost](http://www.boost.org/users/download/) (you'll need to compile for Boost.Filesystem)
|
|
|
|
[Eigen3](http://eigen.tuxfamily.org/index.php?title=Main_Page)
|
|
|
|
[FreeImage](http://downloads.sourceforge.net/freeimage/FreeImage3154Win32.zip)
|
|
|
|
[FreeType2](http://download.savannah.gnu.org/releases/freetype/freetype-2.4.9.tar.bz2) (you'll need to compile)
|
|
|
|
[SDL2](http://www.libsdl.org/release/SDL2-devel-2.0.0-VC.zip)
|
|
|
|
(remember to copy necessary .DLLs into the same folder as the executable: FreeImage.dll, freetype6.dll, SDL2.dll, and zlib1.dll)
|
|
|
|
[CMake](http://www.cmake.org/cmake/resources/software.html) (this is used for generating the Visual Studio project)
|
|
|
|
(If you don't know how to use CMake, here are some hints: run cmake-gui and point it at your EmulationStation folder. Point the "build" directory somewhere - I use EmulationStation/build. Click configure, choose "Visual Studio [year] Project", fill in red fields as they appear, then click Generate.)
|
|
|
|
|
|
Configuring
|
|
===========
|
|
|
|
**~/.emulationstation/es_systems.cfg:**
|
|
When first run, an example systems configuration file will be created at $HOME/.emulationstation/es_systems.cfg. This example has some comments explaining how to write the configuration file, and an example RetroArch launch command. See the "Writing an es_systems.cfg" section for more information.
|
|
|
|
**~/.emulationstation/es_input.cfg:**
|
|
When you first start EmulationStation, you will be prompted to configure any input devices you wish to use. The process is thus:
|
|
|
|
1. Press a button on any device you wish to use. *This includes the keyboard.* If you are unable to configure a device, hold a button on the first device to continue to step 2.
|
|
|
|
2. Press the displayed input for each device in sequence. You will be prompted for Up, Down, Left, Right, A (Select), B (Back), Menu, Select (fast select), PageUp, and PageDown, Volume up and Volume down. If your controller doesn't have enough buttons to map PageUp/PageDown, it will be skipped.
|
|
|
|
3. Your config will be saved to `~/.emulationstation/es_input.cfg`. If you wish to reconfigure, just delete this file.
|
|
|
|
*NOTE: If `~/.emulationstation/es_input.cfg` is present but does not contain any available joysticks or a keyboard, an emergency default keyboard mapping will be provided.*
|
|
|
|
As long as ES hasn't frozen, you can always press F4 to close the application.
|
|
|
|
|
|
**Keep in mind you'll have to set up your emulator separately from EmulationStation.**
|
|
I am currently also working on a stand-alone tool, [ES-config](https://github.com/Aloshi/ES-config), that will help make configuring emulators easier.
|
|
|
|
After you launch a game, EmulationStation will return once your system's command terminates (i.e. your emulator closes).
|
|
|
|
|
|
You can use `--help` to view a list of command-line options. Briefly outlined here:
|
|
```
|
|
-w [width] - specify resolution width.
|
|
-h [height] - specify resolution height.
|
|
--gamelist-only - only display games defined in a gamelist.xml file.
|
|
--ignore-gamelist - do not parse any gamelist.xml files.
|
|
--draw-framerate - draw the framerate.
|
|
--no-exit - do not display 'exit' in the ES menu.
|
|
--debug - print additional output to the console, primarily about input.
|
|
--dimtime [seconds] - delay before dimming the screen and entering sleep mode. Default is 30, use 0 for never.
|
|
--windowed - run ES in a window.
|
|
```
|
|
|
|
Writing an es_systems.cfg
|
|
=========================
|
|
The file `~/.emulationstation/es_systems.cfg` contains the system configuration data for EmulationStation, written in XML.
|
|
|
|
The order EmulationStation displays systems reflects the order you define them in.
|
|
|
|
**NOTE:** A system *must* have at least one game present in its "path" directory, or ES will ignore it! If no systems are found, ES won't even start!
|
|
|
|
Here's an example es_systems.cfg:
|
|
|
|
```
|
|
<!-- This is the EmulationStation Systems configuration file.
|
|
All systems must be contained within the <systemList> tag.-->
|
|
|
|
<systemList>
|
|
<!-- Here's an example system to get you started. -->
|
|
<system>
|
|
<!-- A short name, used internally. -->
|
|
<name>SNES</name>
|
|
|
|
<!-- A "pretty" name, displayed in the menus and such. This one is optional. -->
|
|
<fullname>Super Nintendo Entertainment System</fullname>
|
|
|
|
<!-- The path to start searching for ROMs in. '~' will be expanded to $HOME or $HOMEPATH, depending on platform.
|
|
All subdirectories (and non-recursive links) will be included. -->
|
|
<path>~/roms/snes</path>
|
|
|
|
<!-- A list of extensions to search for, delimited by a space. You MUST include the period! It's also case sensitive. -->
|
|
<extension>.smc .sfc .SMC .SFC</extension>
|
|
|
|
<!-- The shell command executed when a game is selected. A few special tags are replaced if found in a command, like %ROM%. -->
|
|
<command>snesemulator %ROM%</command>
|
|
<!-- This example would run the bash command "snesemulator /home/user/roms/snes/Super\ Mario\ World.sfc". -->
|
|
</system>
|
|
</systemList>
|
|
```
|
|
|
|
The following "tags" are replaced by ES in launch commands:
|
|
|
|
`%ROM%` - Replaced with absolute path to the selected ROM, with most Bash special characters escaped with a backslash.
|
|
|
|
`%BASENAME%` - Replaced with the "base" name of the path to the selected ROM. For example, a path of "/foo/bar.rom", this tag would be "bar". This tag is useful for setting up AdvanceMAME.
|
|
|
|
`%ROM_RAW%` - Replaced with the unescaped absolute path to the selected ROM. If your emulator is picky about paths, you might want to use this instead of %ROM%, but enclosed in quotes.
|
|
|
|
|
|
gamelist.xml
|
|
============
|
|
|
|
The gamelist.xml for a system defines metadata for a system's games. This metadata includes an image (e.g. screenshot or box art), description, and name.
|
|
|
|
**Making a gamelist.xml by hand sucks, so a cool guy named Pendor made a python script which automatically generates a gamelist.xml for you, with boxart automatically downloaded. It can be found here:** https://github.com/elpendor/ES-scraper
|
|
|
|
If a file named gamelist.xml is found in the root of a system's search directory OR within `~/.emulationstation/%NAME%/`, game metadata will be loaded from it. This allows you to define images, descriptions, and different names for files. Note that only standard ASCII characters are supported for text (if you see a weird [X] symbol, you're probably using unicode!).
|
|
Images will be automatically resized to fit within the left column of the screen. Smaller images will load faster, so try to keep your resolution low.
|
|
An example gamelist.xml:
|
|
```
|
|
<gameList>
|
|
<game>
|
|
<path>/home/pi/ROMs/nes/mm2.nes</path>
|
|
<name>Mega Man 2</name>
|
|
<desc>Mega Man 2 is a classic NES game which follows Mega Man as he murders eight robot masters.</desc>
|
|
<image>/home/pi/Screenshots/megaman2.png</image>
|
|
</game>
|
|
</gameList>
|
|
```
|
|
|
|
The path element should be the absolute path of the ROM. Special characters SHOULD NOT be escaped. The image element is the path to an image to display above the description (like a screenshot or boxart). Most formats can be used (including png, jpg, gif, etc.). Not all elements need to be used.
|
|
|
|
The switch `--gamelist-only` can be used to skip automatic searching, and only display games defined in the system's gamelist.xml.
|
|
The switch `--ignore-gamelist` can be used to ignore the gamelist and use the non-detailed view.
|

Themes
|
|
======
|
|
|
|
By default, EmulationStation looks pretty ugly. You can fix that. If you want to know more about making your own themes (or editing existing ones), read THEMES.md!
|
|
|
|
I've put some themes up for download on my EmulationStation webpage: http://aloshi.com/emulationstation#themes
|
|
If you're using RetroPie, you should already have a nice set of themes automatically installed!
