Whoops, there was an issue on some Windows builds regarding update checking, sorry!

(Also, a typo was fixed in the welcome message)

  • GetStringInput var ('$') support in the variables pane
  • Button to toggle the ASCII side of the memory view
  • Support for transferring bundle files (.b83/.b84)
  • Added more icons everywhere
  • Full screen modes (F11 key)

GUI improvements

  • Better layouting behaviour of some panes regarding resizing and extra space/margin
  • Use a more appropriate location for the FPS indicator (bottom right of the status bar)

  • The bottom corners of the keypad are now rounded
  • Append the git SHA next to the CEmu version labels
  • Updated the about window with more credits and better layout

Other improvements

  • The disassembler code has been replaced by a new one written from scratch by @jacobly0, zdis
  • The built-in memory view code has been rewritten and is now much shorter and to the point
  • The built-in console has been revamped, it supports more things and is faster now

  • Improved variable content preview support (underlying library updated)
  • Improved timer-related code in the core
  • Improved OS keypad scanning hardware-like accuracy
  • Qt 5.10.1 + a newer MSVC version are now used to build the default Windows binaries

Version 1.0 is here!

Many new features have been developed the past few weeks/months, you should definitely update to this version.
Note: if you had a previous version installed, we advise you to click "Yes" on the startup popup telling you some old (and probably incompatible) settings should be deleted.

Downloads for various OSes are listed above. For Linux releases hosted on the OBS, please go here.
More download options are also available on this page.


CEmu is a third-party TI-84 Plus CE / TI-83 Premium CE calculator emulator, focused on developer features.
The core is programmed in C and the GUI in C++ with Qt, for performance and portability. CEmu works natively on Windows, macOS, and Linux.

Here are some screenshots showcasing some of the features and various layouts, on these OSes:
