EmulationStation
================

A graphical front-end for emulators with controller navigation. Developed both on and for the Raspbery Pi. Intended for use with RetroArch, but it can easily be used with other emulators.

RetroArch for the Raspberry Pi can be found here: https://github.com/ToadKing/RetroArch-Rpi
I'm not associated with RetroArch in any way!

A cool guy named petrockblog made a script which automatically installs RetroArch, its cores, 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

Building
========

**On the Raspberry Pi:**

EmulationStation has a few dependencies. For building, you'll need SDL 1.2, SDL_mixer, FreeImage, FreeType, and Boost.Filesystem, which can easily be obtained with apt-get:
```
sudo apt-get install libsdl1.2-dev libboost-filesystem-dev libfreeimage-dev libfreetype6-dev libsdl-mixer1.2-dev
```

There are also a few libraries already on the RPi (located in /opt/vc/, like the Broadcom libraries, EGL, and GLES). You can build EmulationStation by simply running `make`.


**On something else (desktop):**

EmulationStation can also be built on a "normal" Linux system. You'll need the same libraries listed above:
```
sudo apt-get install libsdl1.2-dev libboost-filesystem-dev libfreeimage-dev libfreetype6-dev libsdl-mixer1.2-dev
```

You'll also need OpenGL. I don't know the proper package name, but you'll need `/usr/include/GL/gl.h` and `libGL`. You probably already have it. You can build with `make -f Makefile.x86` (badly named Makefile, I know).

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. Keep in mind you can define more than one system! Just use all the variables again. Also, you can use multiple extensions - just separate them with a space, e.g.: ".nes .NES .bin".

If an SDL Joystick is detected at startup, and $HOME/.emulationstation/es_input.cfg doesn't exist, an Input Configuration screen will appear instead of the game list.
This should be pretty self-explanatory. If you want to reconfigure, just delete $HOME/.emulationstation/es_input.cfg.

Mappings will be applied to the first joystick with the same name as the joystick you configured.
An Xbox 360 controller with the xboxdrv driver was used for testing. POV hats are automatically mapped to directions (so if you're not using an analog stick, you'll need to skip mapping Up/Down/Left/Right by pressing a keyboard key).

**Keep in mind you'll have to set up your emulator separately from EmulationStation.**
If you're using RetroArch, a handy input config generation tool can be found in the tools/ subdirectory - you can use it with `retroarch-joyconfig -o ~/.retroarch.cfg` or something similar. You may need to tell RetroArch to load this config file with `-c ~/.retroarch.cfg` in your RetroArch launch commands.

EmulationStation will return once your system's command terminates (i.e. your emulator closes).


**Keyboard mappings:**

Up - Scroll up

Down - Scroll down

Left - Last system (if it exists)

Right - Next system (if it exists)

Enter - Select

Escape - Back out of a folder

F1 - Open the restart/shutdown system menu

F2 - Open the fast select dialog

F4 - Close EmulationStation (should work as long as ES hasn't frozen)

Unfortunately, there is no built-in way to change keyboard mappings - if you need to, check out `src/InputManager.cpp`. There's a switch statement with a list of keys; it should be pretty simple to change them.

gamelist.xml
============

If a file named gamelist.xml is found in the root of a system's search directory, it will be parsed and the detailed GuiGameList will be used. This means you can define images, descriptions, and different names for files. Note that only standard ASCII characters are supported (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 absolute 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.

**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

Themes
======

By default, EmulationStation looks pretty ugly. You can fix that. If you want to know more, read THEMES.md!

There is no special place to download themes right now, but you might be able to find some old ones in the GitHub "Theme Support" issue. The RetroPie setup script also automatically installs a few.
