A new version of the Super Nintendo emulator bsnes has been released. The author (byuu) has been very busy this summer, so the list of changes in version 0.109 is huge::
  • greatly improved macOS support, fixing all obvious bugs and adding fullscreen support
  • added libretro target [Themaister, rtretiakov]
  • much smarter automatic HD mode 7 perspective correction support [DerKoun]
  • added CPU and SA-1 overclocking support
  • added fast forward speed limiting
  • added a new "hotfixes" option to fix critical (deadlocking) bugs that also occur on real hardware (eg for Dirt Racer)
  • added options to emulate bugs in ZSNES and older Snes9X releases to increase compatibility
  • added dialog for IPS patching to choose whether they were made for headered or unheadered ROMs
  • lowered volume during fast forwarding and rewinding to reduce audio distortion
  • added option to mute sound during fast forwarding and rewinding
  • added an option to deinterlace all SNES games by rendering at 480p (almost no speed hit; highly recommended)
  • added multi-monitor support to Windows, Linux, and BSD
  • improved pause and frame advance support
  • improved mosaic emulation for the fast PPU
  • added entropy (randomness) settings; default to no randomness for movie recording (guarantees consistent playback)
  • improved MLT_REQ Super Game Boy emulation; fixes Killer Instinct to default to player 1 instead of player 2 [endrift]
  • added option to disable video dimming during pausing (useful for screenshots with window decorations)
  • redesigned the settings and tools windows to use lists instead of tabs
  • redesigned the input and hotkey settings windows to be easier to use and with clearer naming + icons
  • added option to make hotkeys combinatorial (eg Ctrl+F) instead of separate (eg F11 or Gamepad L-shoulder)
  • restructured the settings menu to be more intuitive
  • fixed path selection dialog from sometimes appearing offscreen
  • added wildcard search support to the file loading window
  • fixed the --fullscreen command-line option
  • redesigned the thread scheduler to allow enhanced compatibility with SA-1 and SuperFX overclocking
  • fixed the pseudo-hires blur emulation support with the accuracy PPU
  • removed template integer classes from the fast PPU to make the code more portable
  • removed icarus from bsnes and merged the heuristics directly into bsnes itself
  • ~5% speedup by optimizing CPU memory accesses and the PPU counters
  • fixed an out-of-bounds memory access in the DSP core [Sour]
  • enhanced the snow effect with depth-of-field and alpha blending support
  • double-clicking a cheat finder result will now add the new cheat code directly
  • added "[HLE]" indicator to the title bar when coprocessor HLE is being used
  • simplified game titles with multi-carts (eg omit "Super Game Boy +" in SGB mode)
  • the emulator now pauses on Windows when navigating the menus
  • added SNES support for decoding Game Genie and Pro Action Replay codes
  • added Game Boy support for decoding Game Genie and Game Shark codes
  • added many more tooltips to explain GUI functionality
  • minor speedups to SuperFX and Cx4 emulation (via object locality)
  • simplified the mode 7 rendering code for the accurate PPU
  • suppress Alt+F4 while in fullscreen mode
  • fixed every reported regression caused by the speed optimizations I've been adding recently
