1.  Keys
--------------------------------------------------------------------------------------
	There are only three keys used in this program, yet...  They are:
	
		MODE 	- Select Next Picture in RAM

		CLEAR	- Quit from the Menu
			- Return to the menu from Viewing a Picture

		ENTER	- Veiw Picture


2.  History
--------------------------------------------------------------------------------------
01/20/00 -- Update
		-Notes:
			I improved the routine that copies the image to the screen slightly, such
				that it is only one byte smaller (big deal).  Also, the byte of
				difference meant that i had used another command, which greatly
				improved the preformance and speed of this version.  It looks a bit 				better, and that is all that changed

12/15/99 -- New Version!
		-Notes:
			You may wonder what makes this version 1.0 instead of version 0.3... Well,
				here's why.  In the previous versions of this program, I cheated and 
				used Joe Wingbermuhle's "ionLargeSprite" and "ionFastCopy" routines. 			
				(Thanks, Joe!) In this version, however, I used my own sprite
				routine (*YAY!*). Instead of copying the image to the graph buffer
				and then copying the graph buffer to the screen, I made a routine 
				that copies the sprite directly from it's RAM location to the 
				screen.  This greatly improves the performance of the program, and
				improves the image quality.  Now, the four-color grayscale is
				almost flawless (no flicker), but the 8-color grayscale leaves 
				something to be desired.  That is my opinion, even though it is
				MUCH better than the previous method.

		-Keys are still the same
		-Updated the Regular 83 version
		-Now, instead of using ION's XOR routine, it uses the equivelent of an AND routine,
			so you may now use tools like "iStudio 1.1" to make images, but then you
			have to add the header, still.

11/27/99 -- Update!
		-Forgot to include instructions on how-to-use in the actual program.
			-Added in this program
		-Fixed missing pixel bug in the title
		-Update only for the 83+ Version.

3.  Requirements
--------------------------------------------------------------------------------------

	- An 83 or 83+
	- Ion v1.1
	- At least one picture file -- Will automatically exit if you don't have
				       one in RAM

I am releasing the source code with this, but please don't copy it and put your name on it... I
especially don't want the source code for my Direct-Copy Sprite routine used without my permission. 
Also,if you make a change/revision to the code, please email me a version. (PMarks@employees.org)

For information on making pictures, see GPic_Dev.txt

4.  Known Bugs
--------------------------------------------------------------------------------------
Sorry to announce that this version has a couple of bugs that I know of.  The first, most important
one is on the 83.  There is no routine to do something that I use on the 83+, so this version still has the pixel bug.  All of the pixels on the right side of the screen in the Main Menu, are off.  

		-83:
			-Right column pixel bug still persists (sorry, guys)
