These files are for the TI-84 Plus CE, 83 Premium CE, and other "CE" calculators with color screens. BASIC programs are compatible with the TI-84 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.

Many assembly programs for the CE calculators are written in C, and will require a copy of the C libraries on the calculator in order to run.

  5. This program is a modified version of Cesium, called AGAME that does not let the user transfer games to other calculators. It also provides a passcode feature to Cesium. Please note that someone with strong calculator knowledge may be able to get around these features, so CesiumDRM is reccomended for teachers to use on students. Most students will not know how to circumvent the restrictions.
    CESIUM is a slim shell and launcher program that has support for running programs regardless of archive status, an organized and colorful GUI, and, most importantly, includes support for relocatable C and ASM libraries for use in other programs. Hide programs, lock BASIC programs from editing, and more with Cesium. Enjoy!
