These files are for the TI84 Plus CE, 83 Premium CE, and other "CE" calculators with color screens. BASIC programs are compatible with the TI84 Plus CSE and some BASIC programs written for monochrome 83+/84+ calculators will also work correctly. Assembly and C programs must be written for the CE calculators specifically; running them on calculators with an OS newer than 5.5 requires jailbreaking the calculator.

First Fantasy is one of the first RPG ever released for the TI84 Plus C Silver Edition and the first ever one for the TI84 Plus CE, TI83 Premium CE and TI82 Advanced Edition Python! The CSE version uses Doors CSE 8.1 libraries to enhance TIBASIC language, while the CE/82AEP version uses CE Textlib and a custom font. This very loose remake of Mana Force for the 83+ brings enhanced graphics, new magic spells and enemies, new cutscenes, expanded storyline and many new challenges. There are 16 magic spells available, 7 character classes, 8 dungeons (12 in the CE version), 49 monsters (77 in the CE version) and several hours of gameplay. If you are a fan of SquareEnix Japanese roleplaying games such as Final Fantasy, then you should try it!

I wrote this program for the classic Pong game in my spare time when I started experimenting into game programming. This version is a two player version of pong, where two players play each other on the same calc, Left player using 2nd and Alpha to move, and the Right player using the Up and Down keys. You a score a point when your opponent lets the ball slip past his defenses. First to 5 points wins! Have fun playing this game, looking at the code, or whatever you want. Just don't take credit for it. This version comes with two types, a full screen game (prgmAPONG), which is easier (more time in between hits to calculate where to hit the ball), and a shorter screen game (prgmAPONGSML) which is harder (less time to calculate where to hit the ball).

I know that James Vernon and Patrick Davidson already made much better TI84 Plus CE shootemups in ASM (Spaze Invaders and Calcuzap), but for a long while I wanted to jump in the 2D space shooter bandwagon and decided to make one written in hybrid TIBASIC: GalagACE. Basically, this game is a remake of the crappy Space Invaders clone I made in early 2002, which could be found in Omnimaga Pack 25 games in 1. I decided to rename it to GalagACE, which is a play with the words Galaga, Ace and CE. I am now using sprites rather than the home screen. This remake now has 18 stages, new scoring system, allows you to shoot three bullets at once and new graphics.
