BlitterStudio/amiberry v8.1.5

on GitHub

Amiberry 8.1.5 is a feature and stability release focused on configuration handling, new FPU options, GUI polish, and platform fixes across macOS, Windows, Android, and libretro.

This update adds optional 80-bit Softfloat FPU emulation, a brand-new ImGui-based on-screen keyboard, adaptive VSync, persistent per-config filter settings, a refreshed macOS full-window behaviour, groundwork for iOS, and a long list of bug fixes across the GUI, .uaem sidecar metadata, CD/filesystem path handling, and Android input.

New Features

• Softfloat FPU (80-bit): Added optional Softfloat support for 80-bit FPU emulation, selectable when accuracy matters more than speed.
• On-Screen Keyboard: Replaced the legacy bitmap virtual keyboard with a new ImGui-based on-screen keyboard.
• GUI: Window title now shows the loaded configuration name and its modified status.
• GUI: Added screenshot controls to the Misc panel.
• GUI: Filter settings now persist per configuration. (#1954)
• GUI: File dialogs now include missing extensions in their filters.
• .uaem sidecar: Exposed sidecar metadata options in the GUI, and reduced unnecessary .uaem creation.
• VSync: Added an adaptive VSync mode, decoupled frame pacing from swap blocking, and removed the old lagless path.
• Windows signing: CI now integrates SignPath to sign Windows artifacts.
• libretro: Added support for .hdf images.

Bug Fixes

• GUI: Fixed the empty controller dropdown in the Add/Edit Hardfile dialogs.
• GUI: Fixed chipset fields not syncing when toggling internal IDE/SCSI boards. (#1956)
• GUI: Raised the HD/directory mount limit to 50 entries. (#1950)
• GUI: Fixed UI scaling on Windows.
• GUI (X11): Fixed the GUI staying in the foreground on resume under WM-less X11. (#1962)
• CD Dialog: Fixed the start path for the CD image dialog, empty-slot CD browse, and relative CD browse paths.
• Filesystem: Fixed relative filesystem and hardfile config paths. (#1957)
• Paths: Initialize multipath search directories from the configured default paths.
• .uaem: Fixed timestamp updates after file writes, timestamp-only sidecar creation, and preserved explicit file dates on close; my_utime paths are now converted to UTF-8.
• Input: Made multi-mouse opt-in and fixed port shuffling on toggle. (#1906)
• Softfloat: Fixed uae_u64 / uint64_t type mismatch and build errors on Linux and libretro.
• SDL3_image: Fixed bundled packaging and added an independent per-library bundling fallback.

macOS

• Fixed the GUI window filling the entire screen after full-window emulation. (#1930)
• Fixed full-window focus handling.
• Switching from fullscreen to full-window now takes effect without restart.

Android

• Fixed controller input: custom mapping, pause button, and mapping UI navigation.
• Fixed the on-screen joystick not working at startup, and the pause menu Advanced Settings entry.
• Fixed the on-screen joystick setting from the Kotlin UI.
• Allowed multi-file selection when importing in the File Manager.
• Switched to a time-based versionCode so internal builds are unique without bumping the CMake version.
• Removed maxSdkVersion from the manifest, bumped AGP, and refreshed dependencies.
• General UX improvements.

iOS

• Groundwork: Added CMake infrastructure, platform guards, and packaging for iOS builds.
• Phase 2: Added dependency gating and compilation fixes for the iOS Simulator.

libretro

• Restored save_state_internal and restore_state_file for the libretro build.
• Added the missing SDL_GetWindowFullscreenMode stub.

Core / Sync

• Synced with the latest WinUAE updates (through 6100b1).
• Updated ImGui to the latest version.

Packages for Linux, macOS and Windows are included with this release.
Android testing release invites will start going out to the project supporters shortly.
