We've had some nice feedback and bug reports after the v1.0 release!
This new "minor" update (actually, it's pretty big) addresses most reported issues, add new things, and improves others.


  • Handling of invalid ROM types (for example, if a non-CE ROM is loaded)
  • Setting to choose the update rate of the FPS and emulation speed indicators
  • New no-settings CLI argument (in order not to load or save them)
  • Ability to force-redistribute the panes by double-clicking on their borders
  • FP and OP stacks viewer/editor (new pane), assuming normal OS execution
  • Message types and colors support in the console pane
  • TI-Basic syntax highlighting added to the variable viewer
  • 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)
  • Use a higher-resolution icon set
  • 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
  • The memory and stack views now support infinite scroll
  • Dock grouping is now optional and togglable in the settings

Other improvements

  • Check write permissions on the settings folder and use portable configuration as fallback
  • Use a more appropriate path for settings storage
  • Try to migrate as many settings as possible between versions
  • The disassembler code has been replaced by a new one written from scratch by @jacobly0, zdis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
  • Simplified and reworked debugging-related code in the core (stepping, watch/breakpoints...)
  • 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

Bug fixes

  • Don't show the no-update-available popup for the auto-check (was already backported into 1.0)
  • Fix portable mode behavior and paths (especially on macOS)
  • Fix invisible new "Memory view" window (Windows-only bug)
  • Fix various threading related issues
  • Fix incorrect screen recording speed
  • Fix floating windows' behaviour and default look
  • Fix sorting issue with the state list
  • Fix CLI sending and use a delay compatible with old ROMs
  • Fix state restoring conflicting with translations
  • Fix incorrect interrupt trigger on a specific LCD condition
  • Fix LCD displaying garbage data under specific conditions when SPI was used
  • Fix LCD dock being cropped off by 1 pixel at the top in some conditions

Version 1.0 is here!

Many new features have been developed the past few weeks/months, you should definitely update to this version.

Downloads for various OSes are listed above. For Linux releases hosted on the OBS, please go here.

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:
