	             Acorn Port by David McEwen 
	            Port Version : pre-release 1.6 (1/10/2001)


In this version
---------------

Not much port specific stuff...
Speed improvements to standard 8 and 16bit modes (ie no hires support or filtering).
Fully in sync with the main source (so Pilotwings runs... slowly...)
Haenous bug with Super FX stuff - DO NOT RUN ANY SUPER FX GAMES!!! - will be resolved asap

In last version 
---------------

Bug fixes - choosing a 16bit filtered mode (Super Eagle, 2xSai or Super 2xSaI) no longer 
causes the emulator to crash.
Added option to have bilinear filtered mode 7 stuff (to make Mario Kart chug some more ;-) )
Preliminary sound!
Cleaned up some of the code, so exiting is nicer as is not beingable to access the screen mode.


Coming Soon
-----------

 * Speed
 * Better Sound
 * Save games
 * Zip support
 (In no particular order)

	                          
Introduction
------------

This is a port of the excellent SNES emulator. It is being actively developed and runs
most things you can throw at it. With the back catalogue of Nintendo games that exist on 
the SNES you can have a hell of a lot of fun with this! Oh yeah and there's Starfox...


Note for users of old machines
------------------------------

Errr... don't even try ;-)


How do I use it ?
-----------------

This port differs from my others in that it isn't set up so that you can just download
a game set the filetype, double-click and play. Although if you so desire you can set it
up to do that. 

I have tried to keep the setup compatible with the previous port, so frontends that exist
should work... although I haven't tried them yet.

To get a game running you first need to get one... once you have done that extract the
rom to either the same directory as the emulator or the ROMS subdirectory. Allocate a 
reasonable wimpslot (it'll vary depending on the game you want to play). If you get an error just allocate more -> sorry its not very clean atm, this will be sorted out. Then set the dir with
the emulator in as your current selected directory (Set work directory option under RISC OS 4).
Then type :

Snes9x <rom name>

This will run the game in 8 bit colour with auto frame skip. There are various options that you
can set they are listed in a section below (or you can see them by typing snes9x or snes9x -help).

The keys during emulation are :

  Cursor keys control movement

  [SPACE]  - SELECT button   
  [A]	   - A button
  [B]	   - B button
  [Z]	   - Z button
  [X]	   - X button
  [Q]	   - Q button
  [W]	   - W button
  [RETURN] - START button
  [ESC]  - Exit

Only 1 player supported atm. I will change this, but there are more important issues to be 
addressed.


Sound
-----

The sound is very preliminary - ie it works. The main problem is that the emulator itself
is running slowly and the speed of sound is matching that so it sounds slow.

To get sound working you need to load the Digital Renderer module - just double click on
the DRenderer file. Then when you start Snes9x ensure one of your arguments is -sound.
So for example to play Mario in 2xSaI with transparency and sound :

snes9x -2xsai -tr -sound mario

Simple really. You can play with the other sound options avilable if you want, but its probably
best not to.


Command Line Options
--------------------

For most options see the README/TXT file.

There are some specific options :

-help      - this shows the command line options

-bilinear - have bilinear filtered mode 7 (requires 16 bit to be set) can be used along with
the other filtering modes

The following disable -hires if this is set beforehand. If -hiress is set after then the
filtering is disabled.

-supereagle  - uses the Super Eagle 16bit filtered mode 

-2xsai  - uses the 2xSaI 16bit filtered mode 

-super2xsai  - uses the Super 2xSaI 16bit filtered mode
