- SMPC: Eliminate spurious INTBACK interrupts
- SMPC: Prevent COMREG writes when a command is in progress. Fixes some boot issues leading to the "Disc unsuitable for this system" message
- SMPC: Prevent optimized INTBACK report from occurring unless a continue request was sent. Fixes input issues with Yaul-based homebrew
- SMPC: Prioritize INTBACK continue requests over break requests
- System: Tighten synchronization between the two SH-2 CPUs and remove artificial timeslice limit. Improves performance and fixes Fighters Megamix and Sonic Jam intermittent boot issues
- VDP1: Lower command limit to work around problematic games that don't set up a terminator in the command table
- VDP1: Significantly slow down command execution when running the VDP1 renderer on the emulator thread. Fixes Dragon Ball Z - Shinbutouden freeze after SEGA logo
- VDP2: Apply horizontal mosaic effect to rotation background layer. Fixes missing effect on Race Drivin' Time Warner logo
- VDP2: Apply window effect to sprite layer. Fixes graphics going out of bounds in many games
- VDP2: Check for invalid access patterns to determine if NBG characters should be delayed. Fixes background offsets in many games
- VDP2: Disable NBG1-3 only if both RBG0 and RBG1 are enabled simultaneously
- VDP2: Honor access cycles and VRAM bank allocations to restrict pattern name and character pattern accesses. Fixes garbage graphics in Panzer Dragoon Saga, Sonic 3D Blast and Street Fighter Alpha/Zero 2
- VDP2: Invert back screen color calculation ratio. Fixes black background on Sakura Taisen FMVs
- VDP2: Move existing VCounter into VDP2 VCNT register. Fixes Assault Suit Leynos 2 freeze when going in-game and King of Fighters '95 not booting
- VDP2: Synchronize background enable events with the renderer thread. Fixes FMV slicing issues on slow machines on Sakura Taisen
- ymdasm: Fix SCU DSP unconditional JMP disassembly

Обновился эмулятор Atari ST - Hatari.

Emulation improvements:
- 030+MMU:
 - Workaround to correct prefetch data after bus errors
- DSP:
 - Fix: JMP can also form a long interrupt instruction
- VME/SCU:
 - TT / MegaSTE SCU registers and interrupts implemented
- Falcon Videl:
 - Refresh rate of monochrome monitor is now correctly detected with 71 Hz
- MegaSTE:
 - Add support for CPU Freq / Cache control at $FF8E21 when running in cycle accurate mode. This gives cycle exact memory accesses when running at 16 MHz, as well as emulation of the external 16 KB cache
