Added color emulation support to the original “mono” WonderSwan.
Note that WS games on WS are displayed using linear gamma, as opposed to WS games on WSC.
Fixed bugs involving cartridge-side RTC protocol emulation
Improved APU emulation accuracy

Nintendo - Game Boy Advance

Latch lower address lines when accessing ROM during burst transfer
Improved background VRAM access timings
Updated cartridge database
Fixed handling of mid-scanline writes to linear background scroll registers
Fixed some bugs that occurred when pixel accuracy was disabled

Nintendo - Famicom Disk System

Added delay to disk state when swapping disks, resolving issues with multiple games where a disk swap was happening too quickly

Nintendo 64 / Aleck 64

Fixed an issue that could cause an application hang under certain titles that deactivate the VI
Add support for the unreleased port “O.D.T. - Escape… Or Die Trying” to the internal DB
Fixed ID in internal DB for Rampage 2, so controller pak and rumble pak should now work correctly
Added compile-time accuracy flag to bypass IPL2 checksum validation for development purposes
Improved error messaging if the Aleck 64 Pif ROM is missing when trying to load an Aleck 64 game.
Added support for configurable Controller Pak storage sizes
Applied a fix to allow booting ROMs with non-standard PI DOM1 parameters in headers
Disabled super-sampled RDP readbacks: fixes some accuracy issues/passes more test cases in the official RDP test suite.

Nintendo - SNES / Super Famicom

Fixed loading of some games that require additional firmware for chips included in the cartridge

Sega - Master System

Updated PAL only entries in the local DB so that they play at the correct 50Hz

Sega - Mega Drive / Genesis / CD / 32X

Fixed incorrect hash for Wonder Boy in Monster World (USA, Europe) that allows for correct EEPROM detection, making the game playable
Fixed YM2612 LFO ‘AM’ bit emulation (Fixing broken audio in Kid Chameleon and others)
32X: In H32 mode, the display is offset by approximately 3.25 pixels to the right
32X: Fix registers and machine state on reset
CD: Fixed an issue where resetting the system while a game was running would result in the BIOS locking up on reboot.
32X: Improve synchronisation between MD/32X: fixes H/V tests in testpico when running in 32X mode.
Improved VDP IRQ delay emulation
Improve YM2612 timer emulation

Sony - PlayStation

Fixed an assertion in Lunar disc 1 when walking into Alex’s house or the barn to the right of it, preventing a crash.

UI / Program

Fixed a runtime crash on arm64 Linux with builds compiled with GCC
Improved compatibility inside sandboxed environments

Fixed an issue with the displayed release version name on Windows
Fixed an issue causing malformed save directory names when a custom save path was specified
Fixed an issue causing the “missing firmware” error to appear twice
