CURRENTLY IMPLEMENTED SNES9X FUNCTIONS
======================================
* ZIP/JMA support
* Saving/loading of SRAM
* Savestate loading/saving support
  - Up to 10 saveslots
  - Compression of savestates with gzip
* Controls
  - Two player support
  - Multitap support (four player support)

CONTROLS IN ROM MENU
====================
Up				- Go up
Down				- Go down
Left				- Go back five file entries
Right				- Go forward five file entries
L1				- Go back one page
R1				- Go forward one page

Cross				- (If directory selected) enter directory/ (if ROM selected) start ROM
Triangle			- (If ROM selected) start ROM with multitap support
Circle				- (If not in root directory) Go back to previous directory
L2 + R2				- (If you previously exited a ROM) return to game
Select				- Go to settings menu (see 'CONTROLS IN SETTINGS MENU' section)

CONTROLS IN SETTINGS MENU
=========================
Up				- Go up one setting
Down				- Go down one setting
Left				- Change setting to the left
Right				- Change setting to the right

Circle				- Go back to ROM menu

EXPLANATION OF SETTINGS MENU
============================
Display framerate		- This will show the FPS (Frames Per Second) onscreen
Sound Input Rate		- The sound input rate of the SNES' audio processor. Runs fine at default (31942)
Transparency Effects		- Disable transparency effects (*)
Frame skip			- Set frame skipping - normally set to AUTO (*)
Disable graphic windows		- Disable graphic windows (*)
Display button input		- Show button input onscreen (Useful for those who experience button lag so we can determine whether it's actually
				registering something)
Force PAL ROM to NTSC		- Set this to ON everytime you want to play a PAL ROM at 60Hz. This will get rid of the ghosting issue that has been
				affecting everyone. Beware though that certain games had region protection so that you could not play a PAL cart on an
				NTSC machine - this started with Super Mario All-Stars. Other games will simply crash when you attempt this - so this is
				definitely not the way it was intended to run PAL ROMs - it is simply a hack, and it works well on most games. You have
				to set this back to ON for every game you try to load; it will automatically turn itself off after having loaded the ROM
PAL Timing			- Change PAL timing - press Left to set it to 16667 (same as NTSC), and Right to set it to 2000 (PAL) (*)
Shutdown master CPU		- This is a speedup hack if toggled. Does not seem to do much, and has been disabled. (*)
Current save state slot		- Set the save state slot - this way, you can save multiple states and switch inbetween save states
Resolution			- Switch between resolutions - 480p mode, 720p mode and 1080p mode (depending on your monitor's supported resolutions) 
Aspect Ratio			- Switch between aspect ratios 4:3 and 16:10 (16:9 will come shortly, for now choose 16:10 on widescreen - perhaps small
				cutoff at left and right))
Hardware Filtering		- Switch between Linear interpolation (Bilinear filtering) and Point filtering.

* - will probably remove this in the future as there's no point to it


CONTROLS IN-GAME
================
Nothing worth really explaining here - 

R3 + L3				- Press these two buttons together while in-game to go back to the ROM browser menu.

R3 + R2				- Save to currently selected save state slot
R3 + L2				- Load from currently selected save state slot

TIP: You can use any USB controller you like and it will map the buttons on the fly - it is even possible to hotswap joysticks - remove one from the
USB port, replace it with another one - it should all work fine. even SNES-to-USB converters should work.

To play a game with a USB controller as Player 1, start up your PS3 and rather than using the Sixaxis/DualShock3, plug in an USB port before
connecting the controller to the PS3 - your USB pad should then become Controller 1.

SOURCE CODE REPOSITORY
======================
This release corresponds with revision = 768cf9df52 

Source code repository is here:

https://code.google.com/p/snes9x-ps3/

COMPILATION INSTRUCTIONS
========================
NOTE: ONLY FOLLOW STEP 1 IF YOU HAVE SDK 1.92 OR LOWER
1 - Edit the Makefile and remove the following from PPU_CXX_FLAGS and PPU_CFLAGS:

-DPS3_SDK_3_41

3 - Do 'make clean && make && make pkg'


CURRENTLY KNOWN ISSUES (AS OF BUILD 4.3.8)
==========================================
* PAL ROMs will be a bit jerky. It is advised that you patch the few ROMs that did not have an NTSC release (such as Terranigma) to NTSC
(there are tools available) and always load the NTSC ROM where there's a version available instead of the PAL version.

PAL versions were almost always inferior to the NTSC versions with 16.9% slower speed and borders top and bottom (due to the extra vertical lines -
PAL had 576 vertical lines, while NTSC had 480)

* One person so far has reported that both builds will not display on his monitor - the reason for that is because his monitor apparently does not
support a 59.94Hz refresh rate, which is essential to getting the very best performance. I will have to provide a workaround for this shortly.
However, 59.94Hz should be the first and preferred option to choose since it currently gives the best results.

NOTES IN GENERAL
----------------
* For people running this on HDTVs complaining about input lag:
	- Turn off all post-processing filters you may have running - on Sony Bravia HDTVs, display Motion Flow (this also causes input lags
	with most games in general, not just this SNES emu. If your HDTV has a 'Game' mode or something of the sort, select that as well.

PERFORMANCE NOTES
=================
* Here is how most games will run (at any resolution - 480p/720p/1080p):

- Normal games (no special enhancement chips)							 = 60fps constant
- DSP-1 (Super Mario Kart/PilotWings)								 = 60fps constant
- DSP-1B (Ballz)										 = 60fps constant
- DSP-2 (Dungeon Master)									 = 60fps constant
- DSP-4 (Top Gear 3000)										 = 60fps constant
- SA-1 (Super Mario RPG/Kirby Superstar/Kirby's Dreamland 3/Super Bomberman Panic World)	 = 60fps constant
- Cx4 (Mega Man X2/Mega Man X3)									 = 60fps constant
- OBC-1 (Metal Combat: Falcon's Revenge								 = 60fps constant
- SDD-1 (Star Ocean/Street Fighter Alpha 2)							 = 60fps constant
- S-RTC (Dai Kaiju Monogatari 2)								 = 60fps constant
- SPC7110 (Far East of Eden Zero/Tengai Makyo)							 = not tested
- SuperFX
  - Star Fox 1											 = 60fps constant
  - Stunt Race FX										 = 60fps constant
  - Doom											 = 60fps constant
  - Super Mario World 2: Yoshi's Island								 = 60fps constant
  - Star Fox 2											 = not 60fps constant
  - Vortex											 = not 60fps constant
  - Winter Gold											 = 50fps constant (was a PAL game)
  - Dirt Racer											 = 60fps constant


PLANNED IMPROVEMENTS
--------------------
* Include keyboard support and map it by default to the following buttons:
- b,a,y,x,l (for face and trigger buttons)
- arrow keys for D-pad
- start = enter
- select = shift
Also make this configurable
* A better frontend
* Cheat code support
* Pixel shaders
* Super Scope support (using analog stick or Move)
* Mouse support (using analog stick or Move)
