NESd 0.15.0

Added

• Added support for Bandai FCG (mapper 16)

Changed

• The emulator display can now fill the entire screen
• Improved compatibility with Android and macOS
• Greatly reduced the performance cost of the rewind feature, especially on lower-end devices
• The emulator core now runs on a dedicated background thread, reducing stutter and making emulation smoother
• Volume hotkeys now adjust the persisted volume setting instead of a session-only value
• Emulation speed now locks to actual audio playback, fixing gradual audio drift and pops after stutters
• Frames are now presented in sync with the display refresh, reducing judder
• Audio recovers from underruns faster
• Fast-forward now mutes audio instead of producing crackling
• Improved emulation core performance
• Frames are now uploaded directly to the display surface on Android, removing a per-frame bitmap copy and render pass
• Auto-save and save states no longer cause a periodic hitch (async file IO)
• Console reset no longer restarts the audio device
• Further improved emulation performance on low-end devices by batching PPU background rendering and reducing per-cycle overhead
• Debug overlay now shows the audio underrun count and minimum buffer fill
• Reduced rewind snapshot capture rate on mobile, improving performance on lower-end devices
• Rewind playback now paces against the audio buffer like normal play

Fixed

• Fixed the menu button being covered by the status bar on Android
• Fixed the recent ROM list showing an error instead of the ROMs when a single thumbnail failed to load
• Fixed zapper hits not being detected reliably
• Fixed uninitialized framebuffer memory being visible in areas the PPU never draws
• Fixed some settings getting cut off on Android in portrait mode
• Fixed touch controls not getting enabled when enabling them for the first time
• Fixed battery-backed save RAM not being restored when loading a game
• Fixed a memory leak that slowly increased memory usage during play while rewind was enabled
• Fixed CHR RAM not being writable for iNES 1.0 ROMs without CHR banks
• Fixed a race condition in the native audio buffer that could cause crackling audio
• Fixed multiple corruption issues in save states
• Fix return address bookkeeping in the debugger, fixing step-out
• Fixed a crash when reading save RAM that's smaller than 1 KB
• Unexpected errors no longer kill the emulator thread, and a load that times out now restarts the emulator instead of failing forever
