New Features
Integrated graphics filters: CRT and smooth
Display tool: modify filter, scaling, aspect ratio, and border while gameplay is ongoing
Mapper 45 (GA23C) support, used by MMC3-based multicart cartridges
Fuzzy searching in the file picker, with top matches appearing first
A log viewer (Settings → Debug → View log) with per-line context, copy and file export abilities, alongside a rolling log file
Updates
Nightly Linux builds are now classified as a distinct development flavor, with existing nightly Flatpak installations migrating automatically
Debug tools are accessible through the in-game menu under “Tools” instead of the Debug settings tab and can be associated with keys or gamepad buttons. Previously opened panels are preserved
The execution log now shares its column with debug tools instead of having a dedicated column
Gamepad input now utilizes the upstream gamepads plugin with standardized button and axis names across all platforms. Existing gamepad bindings will be converted as necessary
Updated to Flutter 3.47 and Dart 3.13. The minimum supported macOS version is now 12.0 (Monterey)
Resolved Issues
Corrected touch screen control binders that would deactivate immediately after being tapped, making binding by touch impossible
Fixed the ROM grid on the main menu and the save state screen to prevent overflow on mobile devices and narrow windows
Addressed a situation where opening a debug tool in a narrow window would reduce the game display to nothing
Fixed overlapping debug tools when multiple are open simultaneously
Resolved the issue with arm64 deb and Flatpak files missing from release pages, as they were overwritten by x64 files
Addressed the lack of rewind capability on macOS for Intel Macs and earlier than 26.4, as the bundled LZ4 library was built solely for Apple Silicon. It is now a universal binary operational on macOS 12.0 and newer
Fixed GPU rendering on macOS silently reverting to CPU rendering
Addressed flickering and black frames during rewinding
Fixed graphical corruption in battery-backed games when loading a save state from the main menu
Resolved the issue with ROM thumbnails appearing black on Android
