OpenEmu Changelog

What's new in OpenEmu 2.4.1

Jan 3, 2024
  • This is a quick fix to resolve launching on Apple silicon (ARM) Macs. For now, OpenEmu is still Intel-only and will require the use of Rosetta 2 in order to launch on a Mac with Apple silicon.

New in OpenEmu 2.4 (Jan 3, 2024)

  • This long-awaited release contains many bug fixes, performance improvements, compatibility for later macOS, localization updates, framework upgrades, UI/UX tweaks, and a massive codebase modernization with the majority rewritten in Swift. This large undertaking was a few years in the making, and while there may be a few minor regressions in the short term, the result will leave OpenEmu future-proof and easier to maintain. A full list of changes may be added later.

New in OpenEmu 2.3.3 (Jan 11, 2021)

  • Fixed a crash that can occur on app launch with macOS Big Sur.

New in OpenEmu 2.3.2 (Jan 11, 2021)

  • Added List View saving for column sort and visiblity (right click column to enable/disable) between app launches.
  • Improved UX and relaxed requirements for mitigation of App Translocation / Gatekeeper Path Randomization.
  • Fixed quitting the app during gameplay not showing confirmation alert or saving progress.
  • Fixed List View being unsorted if it was the initial view mode.

New in OpenEmu 2.3.1 (Jan 5, 2021)

  • Fixed shader configurations not persisting.

  • Improved UX to mitigate game launch issues related to Gatekeeper. — Now prompts with requirement to move to your Applications folder on app launch.
