Starting SimEarth
-----------------

New Feature!

Copy protection has been removed from SimEarth.  If you are upgrading
from a previous version, you will no longer have to enter any
information from the manual before loading a new world.

To Start SimEarth:

1. Run the install program to decompress the program file, set the 
default directory, video and sound options.

2. Change to the drive that contains the directory where you installed
SimEarth.

3. Change to the directory where you installed SimEarth.

4. Type SIMEARTH and press the Enter key.

The program will then load and display the SimEarth title screen.  Press 
the space bar or mouse button to clear the title screen and you will be 
presented with a tutorial window. 

If your machine is capable of displaying more than one of the supported 
video modes, SimEarth will allow you to switch to a different mode from 
the command line.  You will first have to either run the install program 
to copy the appropriate files for each video mode or you can copy all the 
files from all the data disks to your SimEarth directory.  Remember if you 
run the install program, the default settings will be set to whatever was 
selected the last time you ran the install program.

Once the you have installed all the video modes, you may use the following 
command line switches to override the default options:

Switch  Graphic mode
/dV     Sets VGA 16 colors 640x480
/dE     Sets EGA 16 colors 640x480
/de     Sets EGA 16 colors 320x200
/d2     Sets MCGA 256 colors 320x200
/dT     Sets Tandy 16 colors 320x200
/dM     Sets EGA mono 640x350
/dm     Sets VGA mono 640x480
/dH     Sets Hercules 720x348

Switch  Sound board
/sa     Adlib
/sb     Soundblaster
/sc     Covox
/si     IBM internal
/st     Tandy

For example, to run SimEarth in the EGA lo-res mode with Adlib sound type:

SIMEARTH /de /sa

and press the Enter key.


Querying in the compressed edit window
--------------------------------------

Because the compressed edit window only displays every other tile, when 
you do a query on a tile it may not display all the information.  If you 
would like to see all the information, turn off the compress edit window 
option.


Tandy TL, TL2, SL, SL2, & RL
----------------------------

If you have a Tandy model TL, TL2, SL, SL2, or RL you will need to set your
video memory to 32k before running SimEarth. Run the setup program that came
with your machine (Tandy DOS disk) to reset your video memory.  For more 
information on how to reset your video memory, consult your Tandy owner's
manual or call Tandy technical support.


Tandy 1000 TX
-------------

SimEarth requires the Tandy 128k memory upgrade kit in order to run on a
Tandy 1000 TX.  Contact your local Tandy dealer for more information on the
Tandy 1000 TX memory upgrade kit.
