------------------------------------------------------------------------------
HOW TO INSTALL THIS
------------------------------------------------------------------------------
Copy the entire folder to your harddrive.

ROMs go into the 'roms' directory, or some subdirectory in the 
RetroArch-360 directory.

------------------------------------------------------------------------------
HOW TO USE THIS
------------------------------------------------------------------------------
On first startup, RetroArch will select one of the dozen or so 
emulator/game cores. The name of the core currently loaded will be 
shown at the bottom side of the screen.

You can now select a ROM that this core supports and load it in the 
Filebrowser.

To select a different core - go to 'Change Libretro core' in the Main Menu. 
Press A to go to a filebrowser where you can select a different core. Press A 
to switch to the emulator/game core.

------------------------------------------------------------------------------

During ingame operation you can do some extra actions:

Right Thumb Stick - Down         - Fast-forwards the game
Right Thumb Stick - Up           - Rewinds the game in real-time 
                                   ('Rewind' has to be enabled in the

WHAT IS RETROARCH?
------------------------------------------------------------------------------
RetroArch is a modular multi-system emulator system that is designed to 
be fast, lightweight and portable. It has features few other emulator 
frontends have, such as real-time rewinding and game-aware shading.

------------------------------------------------------------------------------
WHAT IS LIBRETRO?
------------------------------------------------------------------------------
Libretro is the API that RetroArch uses. It makes it easy to port games 
and emulators to a single core backend, such as RetroArch.

For the user, this means - more ports to play with, more crossplatform 
portability, less worrying about developers having to reinvent the wheel 
writing boilerplate UI/port code - so that they can get busy with writing 
the emulator/porting the emulator/game.

------------------------------------------------------------------------------
WHAT'S THE BIG DEAL?
------------------------------------------------------------------------------
Right now it's unique in that it runs the same emulator cores on 
multiple systems (such as Xbox 360, PS3, PC, Wii, etc). 

For each emulator 'core', RetroArch makes use of a library API that we 
like to call 'libretro'.

Think of libretro as an interface for emulator and game ports. You can 
make a libretro port once and expect the same code to run on all the 
platforms that RetroArch supports. It's designed with simplicity and 
ease of use in mind so that the porter can worry about the port at hand 
instead of having to wrestle with an obfuscatory API.

The purpose of libretro is to help ease the work of the emulator/game 
porter by giving him an API that allows him to target multiple platforms 
at once without having to redo any code. He doesn't have to worry about 
writing input/video/audio drivers - all of that is supplied to him by 
RetroArch. All he has to do is to have the emulator port hook into the 
libretro API and that's it - we take care of the rest.

------------------------------------------------------------------------------
XBOX 360 PORT
------------------------------------------------------------------------------
The Xbox 360 port of RetroArch has the following features:

- Real-time rewinding
- Switching between emulator cores seamlessly, and ability to install 
new libretro cores

Included with RetroArch 360 are a bunch of shaders - including the latest 
version of the popular xBR shader. It is possible to use two shaders 
simultaneously to get the best possible graphical look.

------------------------------------------------------------------------------
EMULATOR/GAME CORES BUNDLED WITH XBOX 360 PORT
------------------------------------------------------------------------------
The following emulators/games have been ported to RetroArch and are included in 
the Xbox 360 release of RetroArch.

For more information about them, see the included 
'retroarch-libretro-README.txt' file.

- Final Burn Alpha (Arcade - various) [version 0.2.97.26]
- FCEUmm (Nintendo Entertainment System) [recent SVN version]
- Gambatte (Game Boy | Super Game Boy | Game Boy Color) [version 0.5.0 WIP]
- Genesis Plus GX (Sega SG-1000 | Master System | Game Gear | Genesis/Mega Drive |
  Sega CD) [version 1.7.0]
- SNES9x Next (Super Nintendo/Super Famicom)
- VBA Next (Game Boy Advance)
- Prboom (for playing Doom 1/Doom 2/Ultimate Doom/Final Doom)
- Mednafen PCE Fast (PC Engine/PC Engine CD/Turbografx 16)
- Mednafen Wonderswan (WonderSwan/WonderSwan Color/WonderSwan Crystal)

All of the emulators listed above are the latest versions currently 
available. Most of them have been specifically optimized so that 
they will run better on 360 (some games would not reach fullspeed 
without these optimizations).

ZIP SUPPORT
------------------------------------------------------------------------------
FOR EACH CORE (except for Final Burn Alpha)
------------------------------------------------------------------------------

There are three modes -

EXTRACT ZIP TO CURRENT DIR: When you press 'X' on a ZIP file in the File Browser,
its contents will be extracted to the current directory. From there, you can 
load the RMO and play.

EXTRACT ZIP TO CURRENT DIR AND LOAD FIRST FILE: When you press 'X' on a ZIP file
in the File Browser, its contents will be extracted to the current directory.
The first ROM that was extracted from the ZIP file that is a ROM will be loaded
automatically.

EXTRACT ZIP TO CACHE DIR: When you press 'X' on a ZIP file in the File Browser, 
its contents  will be extracted to the /dev_hdd1/ partition. From there, 
you can load the ROM and play.

WARNING: Savestates and SRAM files that have been created by loading ROMs
from the cache dir this way will be removed after RetroArch has been closed.

------------------------------------------------------------------------------
FOR FINAL BURN ALPHA
------------------------------------------------------------------------------
Selecting a ZIP file from the Filebrowser will load that game directly.

------------------------------------------------------------------------------
Troubleshooting
------------------------------------------------------------------------------

If you find that RetroArch no longer works for whatever reason, there is
a way to get it back to work -

- Remove retroarch.cfg from the 'Retroarch-360' folder, then start up again.
The Libretro management service in RetroArch should automatically pick a 
random libretro core and write this to the config file.

------------------------------------------------------------------------------
What can you expect in the future?
------------------------------------------------------------------------------
- An official Android port of RetroArch (no, no App Store 'fee' - 'free' 
as in beer AND as in libre - will be the focal point of RetroArch 0.9.8)
- Port of NxEngine to libretro - runs Cave Story (PC version is already done,
runs on big-endian consoles but has too many bugs to be playable)
- Port of MAME 0.72 to libretro
- Port of VICE to libretro
- Port of ScummVM to libretro
- More emulators, more games that will run on RetroArch
- Lots of other crazy ideas that might or might not pan out
