Introduction
LLLLLLLLLLLL
This is a version of the game that introduced the Illusiat series, adapted for the TI-81. The goal was to attempt at fitting the original 2001 version on the TI-81 from 1990 that got discontinued in 1997 to see if it would fit in its limited 2400 bytes of RAM. It has been ported to the TI-82/83/+/SE/84+/SE calculators in 2008 and on the TI-85/86 in 2009 for those who don't own a TI-81 but still want to see how it looks.

Since 2001 there have been 3 versions of Illusiat released, including this one. The first one was my first released RPG ever. The second one was an enhanced remake utilizing Illusiat 12 walking, battle and menu engine as well as some ASM libraries from The Reign Of Legends 2. It came out in 2003 in a bundle called Illusiat 2004, containing remakes of the 4 first Illusiat RPGs in the series, with bigger and more complex maps, improved storyline, added level-up system for the two first games, which didn't used to have one, new magic spells and a lot of major changes.

This new 2008 version of Illusiat is based on the very first version ever but this time for the first TI graphing calculator ever released. Maps are similar to the first game and the graphics aren't as good but there have been some improvements in some areas, most being inspired from the 2003 remake included with Illusiat 2004. This is also the hardest version of all.

Installing and running the game
LLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL
-First make sure to clear your RAM. This game utilizes the entire calculator RAM and all 37 sub-programs.
-Because the TI-81 doesn't have a link port, you need to type in the entire game source code by hand in the PRGM editor. Because of the memory limitations you must type in the matrices as well. Both are located in the Source_Code.txt included with this readme file.
-Afterward to play the game you must run Prgm1.

How To Play
LLLLLLLLLLL

When the title screen appears you are prompted to choose 3 options:
┌────────────────┐
│LLLLLLLLLLLLLLL │
│  ILLUSIAT 81   │
│LLLLLLLLLLLLLLL │
│                │
│C2008 OMNIMAGA  │
│                │
│1NEW 2SAVE 3END │
│?               │
└────────────────┘
To start a new game type the digit 1 then press ENTER. To continue from the last location type 2 then ENTER. To quit type 3 then ENTER. Controls will be pretty much like that during the entire game, except when text appears you may have to press ENTER to continue. Do not select 2SAVE if you are playing for the first time else you will get an error.

After the intro where you are pursued by monsters the ground will break under you and you will land into the Ruins Of Behemoth, which you will have to escape to finish the game. Like in the original TI-83 Plus version of Illusiat, released in 2001, you can't move around inside rooms, you move from room to room. The difference is that due to the lack of a GetKey command on the TI-81, you have to move around by selecting the direction in the same way you selected options on the title screen or the same way you will do inside battles:
┌────────────────┐
│LLLLL     LLLLL │
│          LLLLL │
│          LLLLL │
│          LLLLL │
│          LLLLL │
│LLLLLLLLLLLLLLL │
│1< 2> 3^ 4V 5XP │
│?               │
└────────────────┘
In the 2001 version of Illusiat there was no menu. However, in this version you can at least view your character stats. As you can notice there's a 5th option called "XP". This is where you can view your character LV (level), HP (hit points), MP (magic points), HP/MP CAP (the maximum amount of HP and MP you can have for your current LV) and experience points needed for the next LV. You cannot heal yourself there though. To move around on the map you just need to select the direction from the option.

As you move around you will most likely run into a lot of monsters. There are chances that he attacks first. When it's your turn you can select between 3 battle commands:
┌────────────────┐
│MONSTER!        │
│GOON HITS U     │
│HP              │
│             374│
│MP              │
│             458│
│1ATK 2LIT 3HEAL │
│?               │
└────────────────┘
In the original version of Illusiat there was only one magic spell and you had an infinite amount of potions. However, in this game potions were replaced with a healing spell that also takes MP like the lightning spell (although twice less) to increase difficulty. The MP required by both spells is also higher. LIT takes 20 MP and HEAL 10. Both first and second options deal damage to the enemy, although the second option usually deals greater damage. The 3rd option, as you already guessed it, heals your HP. Both magic spells have a different animation to illustrate its effect.

When you win you receive experience points and when your total experience needed to level up reaches 0 you gain one level. 

In the original version of Illusiat, the first version automatically saved your progress without requiring you to save manually. This was later removed in 2002 and you had to go into specific rooms to save your progress, else, quitting the game would make your restart to your last save position. In the TI-81 version the progress is saved automatically anywhere. However, if you die in battle you have to restart at the beginning of the dungeon or right after the previous boss fight, your LV, HP and MP are restored to maximum but you lose all experience points earned for the next level.

Known Bugs And Problems
LLLLLLLLLLLLLLLLLLLLLLL

Due to the TI-81 restricted memory and TI-BASIC commands, you may encounter some glitches during gameplay. Most of them are unfixable in the current state of the game and are mostly calculator limitations:

-When you are prompted to select an option in a menu, if you press CLEAR everything above the "?" will disappear
-Selecting an invalid option in battles (or a magic spell without enough MP) will cause you to skip a turn.

*IMPORTANT: IF FOR ANY REASON YOU MISTYPED SOMETHING, DECIDE TO MODIFY SOMETHING OR DO ANYTHING THAT WOULD CAUSE YOU TO HAVE SOMETHING AROUND 5 BYTES OF REMAINING RAM, DO NOT OPEN THE LIST EDITOR!!!!!!!! THIS WILL CAUSE THE CALCULATOR TO ACT ALL CRAZY, INSERT JUNK INSIDE PROGRAM NAMES AND IF YOU MESS AROUND FOR TOO LONG AND CHANGE YOUR CONTRAST AFTERWARD OR PRESS THE ON KEY THIS MAY CAUSE YOUR TI-81 TO CRASH AND CAUSE A "Mem Cleared", MEANING YOU MUST RETYPE EVERYTHING AND RESTART FROM SCRATCH!!! THIS APPEARS TO ONLY HAPPENS IN ROM 1.1.*
