Here it is, SimCity for your TI82/83...
 
(Turn your word-wrap on...)

As far as I know, the only SimCity ever made for the TI-82. Has save/restore with data file integrity checking, built-in multitasking capabilities (city continues to grow while building and on selection screen), and about the most complex AI that one can run on a TI82 at an acceptable speed. The TI-82 and TI-83 versions are nearly identical; some program syntax is changed slightly for compatibility with the 83.
 
The option menu:
 
NEW: Creates a new city. This will erase any city currently saved.
RESUME: Resumes a city previously saved. 
Pic1 DELETED: Redraws the city screen, normally saved in Pic1 (In case it has been deleted, eg to save memory)

Playing the game: (I assume you are familiar with the PC version, the SNES version, etc.)
 
You start with $20,000 to build your city. Zones (Residential, Commercial/bong shop, Pot, 'Shrooms, Cocaine) are $500. Press the <2nd> key to get to the selection menu, where you can choose a type of zone to build and see the current month/year in your city. To quit, press <CLEAR> on this option screen. DON'T USE ON/BREAK to quit, or things may not be saved properly. The city is automagically saved to matrix [A].
 
Generally, the more Pot, Shrooms, Cocaine and Bong shops you have, the more people will want to live in your city and the faster it will develop. The more residents you have, the more revenue you will receive per year. Eventually you will come to a point where there is no more room on the screen for any zones. Don't worry! You can stack them on top of each other, just drop a new zone on an existing one.
 
Growth and development:
 
As you build your city and things start growing, you will see the changes onscreen. Undeveloped areas look like this:
(R) Residential, (B) Bong shop, (P) Pot, (S) Shrooms, and (C) Cocaine.
Developed areas will look like this:
([]) Residential (0) ('theta') Bong shop, (a twig-shaped thing) Pot, (o) Shrooms, and (*) Cocaine.
 
At the end of each year a tally of residents, developed areas, revenue and total funds will be displayed.
 
The city will continue to grow and develop as long as you are running the game, even as you are building or on the selection screen. The city screen will not update when on the selection screen, so areas may not look developed even if they are. Passing over them with the cursor (+) will update them, but it really doesn't matter to the program engine.
 
Save and restore:
 
The city is automatically saved when you quit from the option menu. It is loaded from 'RESUME' on the main menu, exactly as you last left it. For faster loading, the image of the city as you last left it is saved in Pic1. If you're hurting for RAM, you can delete Pic1 without any ill effects. If you delete Pic1 or it gets overwritten with a graph (or by another game :) use 'Pic1 DELETED' on the main menu to redraw.
 
You can transfer cities to and from other calculators, just use your Link menu to send Matrix [A]. (You may also want to send the program itself, if the other guy doesn't have it.) The matrix file will be about 1750 bytes.
 
Well, that's about it, I guess. If anyone is interested (bug me about it) I may write some sort of technical documentation, eg. how the program works, how it discourages cheating by checking the matrix file for tampering, the format of the matrix file, and how it determines when a certain zone will or will not develop. (Hint: It's NOT just at random!)
 
Have fun, and make sure you don't get caught playing during your math class :)
