TI-Boy will temporarily replace part of the TI-OS, for greater speed and more available RAM. The creator is not held responsible for any damages caused. This is a beta piece of software (though a well-tested one). Grab the latest pre-built release at or check out the Build Instructions to build from source. TI-83+ and TI-Nspire with 84+ keypad are not supported, and never will be. This was rewritten from scratch since the Alpha version, specifically to support newer TI-84+/TI-84+SE calculators (which have smaller RAM chips).
TI-Boy SE is a Game Boy emulator (no Game Boy Color support) for the TI-83+SE, TI-84+, and TI-84+SE calculators.
