CEmu is a third-party emulator for the eZ80-based TI-84 Plus CE and TI-83 Premium CE graphing calculators, built with a C core and a Qt/C++ GUI. It emphasizes developer features such as breakpoints, a disassembler, memory/CPU viewers, and TI-Basic debugging.
Use cases
- emulate a TI-84 Plus CE calculator on my desktop
- debug eZ80 assembly programs for TI-CE calculators
- test calculator programs without a physical TI-84
- dump and run a ROM from my own TI calculator
- step through TI-Basic code with breakpoints
- capture screen recordings of calculator programs
- profile and benchmark calculator code with a cycle counter
When to choose
- you develop assembly or TI-Basic software for TI-84 Plus CE / TI-83 Premium CE calculators and need debugging tools
- you want fast, accurate emulation with screen capture and state saving on Windows, macOS, or Linux
- you need hardware-revision-specific emulation (ASIC variants) or USB transfer emulation
When to avoid
- you need an officially TI-licensed emulator for classroom compliance (use TI-SmartView CE instead)
- you want to emulate older TI calculators like the TI-84 Plus (non-CE) or TI-83
- you don't have access to a physical calculator to dump a ROM from, since CEmu requires your own ROM
