CEmu does not rely on downloading an OS from TI's website nor does it have a custom boot/loader: a ROM from your own calculator is required. Note that Release builds have an update checking feature, which is disabled in development builds. Official stable releases are available here: If you need an official TI CE emulator, TI-SmartView™ CE is for you. Note: CEmu is not a TI product nor is it TI-endorsed/affiliated. For performance and portability, the core is programmed in C and its customizable GUI in C++ with Qt. CEmu is a third-party TI-84 Plus CE / TI-83 Premium CE calculator emulator, focused on developer features.ĬEmu works natively on Windows, macOS, and Linux.
