Squash 3.1

Introduction
------------
Welcome to Squash 3, the fastest pong game for the TI-83, fully written in assemly!

Installation
------------
The installation of Squash 3 is very simple: just send the file 'ZSquash3.83p' to your calculator. Then you can run it from AShell or a compatible shell, like SOS. If you don't have such a shell yet, you can get it at http://www.ticalc.org.

Playing the game
----------------
The concept is so simple that it is hardly worth explaining, but I'll do so anyway. At the bottom of the screen you see your racket. You can move it with the arrow keys. The goal of the game is to keep hitting the ball, that bounces around the screen, with the racket, so that it doesn't fly off the bottom of the screen. For every hit you score a point. The ball will go a little faster every time it hits your racket.
Squash 3 will automatically save your hiscore, and notify you when you broke it.
WARNING!!! DO NOT SWITCH YOUR CALCULATOR OFF WHILE YOU ARE IN THE GAME!!! At best, is causes the program to disappear from the shell. At worst, it crashes your calculator.

Uninstallation
--------------
You must be kidding, right? Throwing such a good game off your calculator! But if you're determined to do so, simply delete the program 'ZSQUASH3'. There. Now you've done it. How could you.

Squash
------
At the time of writing, there are Squash 1, a TI-BASIC version on the text screen, Squash 2, which runs on the graph screen, and Squash 3, which is written in assembly and runs on the graph screen. They are all available from www.ticalc.org.

Source
------
There is a slightly commented version of the code included, called 'Squash3.z80'. If you have any questions about how the program works, or if you're just curious, have a look at it.

Legal stuff
-----------
Of course this game shouldn't harm your calculator, but it might, and if it does, I reject all responsibility.
