• Improve DMA timings
• Implement that the prefetcher should halt only once DMA is accessing ROM
• Prevent DMA from interrupting ROM accesses
• Fix controls when using a rotated screen
• Reload timer value after tick
• Use separate latches per DMA channel
• Implement graphics viewer in the debugger

Nintendo - Nintendo 64

• Clear R0 register only when written to (Performance optimisation)
• Fix an issue where loading save states would not set the correct audio frequency
• Add missing fields to save states
• Refactor to remove the branch state machine from the instruction epilogue (paving the way for future recompiler improvements)

Sega - SG-1000

SNK - Neo Geo

• Fix an issue where cartridge ram was not included in save states for the Jockey GP mapper.

Sony - PlayStation

Shared Components

ARM7TDMI

• Fix reading SPSR register in user and system modes
• Improve LDM/STM edge case handling

NEC V30MZ

• Fix DAS overflow flag emulation
• Fix instruction prefix handling
• Fix IP on interrupt fired when prefixes are being used with non-prefixed instructions

Other

• Fix an issue where settings may not save correctly on non-english locale
• Improve the OpenGL integration with librashader; matching the implementation for the Metal driver
• Improve the OpenGL driver on macOS: Fix flickering on resize, add fullscreen behavior toggle and fullscreen monitor selection
• Fix building using Make 3.81 (macOS users no longer need to install a newer Make manually to build ares)
• Properly detect the target arch when compiling with CL
• Improve compatibility with FreeBSD
• Fix an issue where the settings window would be too small to show all options on some configurations
• Add the ability to switch between the interpreter and recompiler at runtime; previously this was a compile time switch unavailable to end users. You can use the "Force Interpreter" setting to force the 32X, N64 and PS1 cores to use the interpreter.
