- pdc20262: Hookup PDC20268 Ultra100TX2 [The Retro Web].
- pit8253: Improved timing accuracy (#15064): machine/pit8253.cpp: Improved timing accuracy; the counter is loaded and decremented on the falling edge of CLK; GATE and GATE transitions (for edge-sensitive modes) are sampled on the rising edge of CLK; mode 3 treats GATE as edge-sensitive; in modes 2 and 3, GATE has an immediate effect on OUT; deferred the execution of `set_clock_signal`; removed 8253 timing workarounds from sixtrak. pit8253.cpp: Ensure the recent fix for mode 3 does not yet apply to `set_clk` configurations [m1macrophage].
- prail07: Changed manufacturer to "Takara Tomy" [James Charles Taylor].

- scsi_s1410: Return seek error on out-of-bounds seek [Curt Coder].
- sh7709s: Update bank conflict precharge penalty timing (#15087): Handle the precharge of the last active bank in the background and only pay the penalty on a bank conflict and only pay the remainder of the wait cycles that haven't elapsed since the last access; update the read->write wait penalty time for dirty writeback eviction since wcr1 should contain that value; fix LRU cache replacement updates (#15098). Only update LRU values greater than the current LRU value on cache hit; fix bug in DRC memory accessor using clobbered IO reg (#15074). Fix a shift error in the wcr1 register values Add bcr2 plumbing for determining cache line fetch reads based off BCR2. Area 0 is set via external pins so hardcoding the cv1k value, this is typically code space though so it only affects timing during copy of code to main memory; convert the cpu cycles to bus cycles properly (#15078) [Jesus Ramos].

- sis6326_vga: Add line compare "disable", fix display at 1600x1200; fix lambda capture; implement video overlay playback; improve VCLK PLL handling; preliminary HW cursor; start hooking up MD config pins, base hookup of TV Out space; add remaining Sequencer registers, improve logging; add CRTC counter latches; fix bug with dxdiag setting the wrong ramdac mode from 16bpp fullscreen to 8bpp desktop [Angelo Salese].
- sis950_lpc: Add pin mapper, add PCI slots to base sis630.cpp driver; hookup relocable IDE IIRQA/IIRQB pins [Angelo Salese].
- tmp94c241: Implement DMA subsystem (HDMA + DMAR) and fix port reads (#15003); add serial port sub-device with I/O interface mode (#15015): Add serial port sub-device with I/O interface mode; replace the inline serial stubs (which just instantly set TX-complete) with a proper sub-device implementation supporting: I/O interface mode (mode 0): Synchronous clocked serial using SCLK pin. Supports both internal (baud rate generator) and external (IOC=1) clock sources. TX double buffering with auto-load from buffer to shift register. Pre-outputs bit 0 on TXD before first clock edge so receiver can sample it on the rising edge; baud rate generator: Configurable via BRxCR register with divisor and clock source selection. Timer drives SCLK at the configured rate. Clock frequency derived from CPU clock. TX/RX data callbacks: txd(), rxd(), sclk_out(), sclk_in() for connecting external devices to the serial ports. tx_start callback: Signals the start of each byte transmission with the current PFFC pin function state, allowing connected devices to distinguish real transmissions from phantom ones. The serial registers (SC0BUF/SC1BUF, SC0CR/SC1CR, SC0MOD/SC1MOD, BR0CR/BR1CR) are now delegated to the sub-devices in the internal memory map. TX-complete flags (INTES0/INTES1 bit 7) are set at device_reset to indicate empty TX buffers at power-on. UART modes (7/8/9-bit) are recognized but not yet implemented; also moves interrupt register indices from a file-scope enum to public static constexpr members of tmp94c241_device. tmp94c241: Move IRQ vector map to static const class member: Per galibert's review suggestion: defining the IRQ vector table as a static const member of tmp94c241_device and providing the out-of-class definition in class scope allows the INTE* constants to be referenced without tmp94c241_device:: qualifiers in the initializer. The nested struct is named irq_vector_entry. NUM_MASKABLE_IRQS is replaced by std::size(irq_vector_map) directly at each use site inside member functions. tmp94c241: use enum for public interrupt index constants. tmp94c241: use required_device for serial sub-device parent access. Replace dynamic_cast with required_device using DEVICE_SELF_OWNER to access the parent CPU from the serial sub-device. This provides automatic type checking during MAME's -valid pass. Break the circular header dependency by replacing the #include of tmp94c241_serial.h in tmp94c241.h with a forward declaration and having tmp94c241_serial.h include tmp94c241.h instead. The .cpp files include what they need directly. Addresses review feedback from galibert on PR #15015 [Felipe Corrêa da Silva Sanches].

- w65c02: De-virtualize SBC implementation [AJR].
- w65c02s: De-virtualize SBC implementation [AJR].
- wd1000: Set ID not found error properly (#15070). This makes the wd1000 controller report the ID not found error condition on read or write operations. This fixes an issue with valdocs on the QX010 not detecting a CR1510 hard drive properly. This is due to Valdocs probing the hard disk geometry via the read command and expecting the drive to report an error if the geometry is incorrect [Brian Johnson].
- wd9710_pci: Add extended ports so that it doesn't drop in MDA mode [Angelo Salese].
- x68000: BugFIX #09402 [Media Support] (sharp/x68k.cpp) x68000: Reading floppy disks does not work [AJR].

- abc1600.cpp: Refactor the MAC into a 68008 MMU; fix SASI callback [Curt Coder].
- apple2.cpp: (apple2_cass.xml: Split out required_ram from usage info; many other metadata corrections and improvements. Fix typo [AJR]. Remove phantom (probably lost) ROM set that was always commented out; remove this leftover entry, too [AJR]. (apple2_flop_orig.xml), (apple2_flop_clcracked.xml) Added 50 dumps, combined 2 item, and metadata updates cleanups (#15018). Focus: The great MECC metadata cleanup [A-Noid33].
- cdi.cpp: Add Audio Mixing (#15105): Remove Allocation Removes unnecessary memory allocation in CDDA decoder. The class already has m_samples prepared for this purpose; simplify XA Audio This removes an allocation of 56 bytes by instead using an orphaned array which was intended for this purpose; add Audio Attenuation Storage Breaks existing savestates; reduce crashes from Audio Previously, attenuation commands were not processed resulting in executing data bytes as code. This placeholder properly skips 5 bytes, increasing stability of the system; add Audio Mixing CD-i audio mixing now largely working. To verify, try Zelda Wand of Gamelon and notice the audio now fades correctly; reduce Audio Peaking Changing to 0.25 removes some noticeable audio peaking. For example, the intro Philips logo [Vincent-Halver].
- debut.cpp: Use pwm_display_device for the LCD [hap].
- esq5505.cpp: Add support for the Ensoniq VFX OS version 2.30 ROMs (#15080). UART is an mc68681_device, not an scn2681_device (#15114) [Christian Brunschen].

- sis630.cpp: Move ACPI implementation in own core, add enough SMI glue logic [Angelo Salese].
- spc1000.cpp: Corrected AY-3-8910 clock to 2MHz. (#15103). The PSG on this system is clocked at half the CPU frequency (4MHz / 2 = 2MHz), which is necessary for the sound to be played at the correct pitch and speed [Miso Kim].
- specnext.cpp: Emulated The Spectrum Next UART (#15058). Separated VRAM memory (#15117). The Next moved typical VRAM pages (bank5&7) from SRAM to internal FPGA BRAM. bank7 has only 0x2000 and it's mirrored to the second half - this is also covered in this implementation. KS1..3 variants as clones; Added v30204 BIOS options (#14997). "dot commands" loading issue with NextZXOS - switched back to safer sdcard implementation which not such sensitive to timings (#15066) [holub].
- spectrum.cpp: (spectrum_cass.xml) Added 11 working items + 1 redumped (#15109). Cleanups and fixes: parent/clone relationships, descriptions, publishers, years and languages info. Added "" property (replacing the usage property in several cases) [ArcadeShadow]. Focus on debugger memory window crashing the emulator if exp devices are not activated (#15066) [holub].
