- CPU
  . Dynamic Re-Compiling
    . drcbearm64
      . Added some glue for supporting memory access optimisations. Emit optimised code for native-width reads and writes no larger than native width. Added disassembled UML comments to logged native assembly language (cpu\drcbearm64.cpp).
      . Correctly identify valid immediate constants for add/sub/cmp (it was too conservative). Don't unnecessarily copy UML register values kept in host registers for CMP. Fixed detection of TST against immediate zero and optimised generated code. Optimised TST against immediate with all bits set (cpu\drcbearm64.cpp).
      . Fixed issues with and optimise ADD[C]/SUB code generation. Fixed potential crash on generating code for UML ADDC or SUBB with immediate operands (GitHub #13475). Optimised generated code for various degenerate cases and cases where register loads can be avoided. General cleanup (cpu\drcbearm64.cpp).
      . Minor fixes and optimisations: Clear V/Z/S bits in flags register after SETFLGS or RESTORE. These flags are kept in the native NZCV register and SAVE assumes the corresponding bits in the flags register are clear. Don't use an extra temporary register for SETFMOD with operand loaded from memory. It doesn't allow additional parallelism anyway. Slightly optimised generated code for GETFLGS. Avoid a redundant TST when flags are requested for the non-optimised ROLAND case. Also avoid unnecessarily updating flags when not requested. Don't update flags for ADD/ADDC/SUB/SUBB/AND if not requested. Slightly reduces pressure on the NZCV register. Added TODO notes for opportunities to use CSEL/FCSEL rather than conditional branches (cpu\drcbearm64.cpp).
      . Optimised conditional operations using carry flag. Track the state of the native carry flag to avoid unnecessarily manipulating the native NZCV register. If the native carry flag does nnot correspond to the UML carry flag, test the bit in the flags register nfor the C and NC conditions. Use condition select instructions to implement conditional forms of MOV and FMOV when advantageous. Fixed EXIT with C/NC/A/BE condition not working properly if it doesn't immediately follow a CMP or SUB. Extended reach of conditional EXIT to +/-128MiB (was +/-1MiB for conditions other than U/NU). Moved code to set up skipping conditional instructions to a common function. mUse TBZ/TBNZ for short backward jumps with U/NU/C/NC conditions to save one instruction and a temporary register. Simplified/optimised ADD[C]/SUB code generation - avoids an unnecessary register copy when one operand is in memory and the other is a small immediate value. Also fixed another unnecessary register copy for SUB when an operand is kept in a host register. Slightly optimised generated code for AND immediate. Reduced number of temporary registers used for AND with some operand combinations. Don't emit code for UML NOP - the simplifier litters the code with these for elided operations (cpu\drcbearm64.cpp).
      . Fixed some cases where a conditional MOV could unexpectedly clear the upper bits of the destination. Attempt more optimisation on one more load immediate operation (cpu\drcbearm64.cpp).
    . drcbex64
      . Align HANDLE entry point to 16-byte boundary. Fixed a number of cases where 4-byte operations wouldn't clear the upper half of the destination (there are plenty more of these caused by the simplifier that will be harder to fix) (cpu\drcbex64.cpp)
      . Improved code generation for various arithmetic and logical operations. More AND/OR/XOR/ADD/ADDC operand combinations are optimised. Special cases of ROLAND/ROLINS are optimised. Don't treat operands to FADD/FMUL as commutative. This isn't true when one is a NaN (cpu\drcbex64.cpp).
      . Avoid a lot of unnecessary flag manipulation on shift/rotate operations. Don't calculate flags when not requested. Don't preserve carry in for operations that don't use it as an input. Avoid loading CL when ECX can be used. Loading CL doesn't clear the upper bits, so it depends on the previous value of RCX, causing pipeline dependencies. Loading ECX can grab a fresh rename register (cpu\drcbex64.cpp).
      . Print an error message and abort when running off the end of a generated code block (cpu\drcbe*.cpp).
      . Fixed upper bits of UML registers being cleared when used as address offset for LOAD/STORE. Don't do expensive zero/sign flag update for shift operations if only carry flag will be used. Reduced copy/paste in READ[M]/WRITE[M] generators (cpu\drcbex64.cpp).
    . Realigned some comments that had drifted (powerpc\ppcdrc.cpp)
    . Be explicit about turning nullptr into a pointer to data (util\mfpresolve.h).
    . Handle some more cases where ROLAND can be turned into AND in the simplifier (cpu\uml.cpp)
  . hyperstone E1
    . Use osd_printf_error for diagnositc output and make more local variables const. Get rid of a redundant TEST - ROLAND can set the Z flag (e132xs\e132xs.h and e132xs\e132xsdrc_ops.hxx).
    . Refactored code generation to improve performance and fixed some issues: Moved a considerable amound of logic from execution time to code generation time. Fixed some cases where add/subtract carry was being interpreted incorrectly. Fixed a case where a load double intruction was incorrectly writing the same register twice. Use UML flags to generate condition codes for addition/subtraction. Use UML carry flag for carry-/borrow-in. Reduced UML register pressure (improves performance for hosts with fewer callee-saved CPU registers). Moved more logic to helper functions to simplify maintenance (e132xs\e132xs.h and e132xs\e132xsdrc_ops.hxx).
    . Cleaned up and commented code for generating an exception, reducing about nine memory accesses to update SR to two. Implemented NEGS and fixed ADDS and SUBS not setting excption handler address. Optimised code to update Z flag on logic operations to avoid branches. Reduced copy/paste a bit more (e132xs\e132xs.h, e132xs\e132xsdrc.cpp and e132xs\e132xsdrc_ops.hxx).
    . Made interrupt check function generate far more compact code (about 85% reduction in number of native instructions on x86-64). Optimised out-of-cycles check. Applied prior optimisation for trap/interrupt checks to static exception checks as well (code is still copy/pasted) (e132xs\e132xs.h, e132xs\e132xsdrc.cpp and e132xs\e132xsdrc_ops.hxx).
    . Fixed IO2 interrupt check in recompiler. Also further reduced conditional branches and logic operations in interrupt check. Fixed regression in exceptions (e132xs\e132xsdrc.cpp). Fixed a flags issue in the recompiler (e132xs\e132xsdrc_ops.hxx).
  . MIPS-I: Removed embedded syscall logging (mips\mips1.cpp)
  . MIPS-III: Don't start a new block for every callable helper (mips\mips3drc.cpp)
  . Motorola MC68000 (Musashi) and Motorola MC68000 FPU: Fixed fmovem effective address increment bug (m68000\m68kmusashi.h and m68000\m68kfpu.cpp)
  . NEC V60: Improved CVTSW flags and fixed issue with float-to-u32 cast. Implemented correct rounding mode when converting float to integer (v60\op2.hxx).
  . Zilog Z80: Switched *R (LDIR, OTIR, etc) debugger flag to STEP_OVER (z80\z80dasm.cpp)
- SOUND
  . Namco /15xx/CUS30: m_voices is a configuration parameter, so it shouldn't be part of the save state (sound\namco.cpp).
  . Seibu Sound System: Read coin inputs through sound device. Coin inputs are read through the sound MCU, so this documents the connections better and allows fake I/O ports to be removed. Also cleaned up code and improved tags.
  . TMS52xx: Enable command buffering during speak operation. Removed legacy spchrom implementation (sound\tms5220.cpp).
  . TMS5220: Five an example VERBOSE value that will actually do something rather than LOG_GENERAL which isn't used in the file at all.
- DEVICE
  . Floppy
   . Internal overhaul. Replaced custom reference counting wrapper with std::shared_ptr. Renamed fsblk_t::block_t::copy to write and use it in a few more places. Added fsblk_t::block_t::read. Renamed fsblk_t::block_t::offset and rooffset due to name collisions and privatize these helper functions. Renamed fsblk_t::fill to fill_all for clarity's sake (formats\fsblk.cpp).
   . Return INVALIDIMAGE from floppy_image_device::identify if no format scores (imagedev\floppy.cpp).
  . Intel 82371 southbridge, MediaGX CS5530 Bridge, SiS 85C496/497 chipset and SiS 950 LPC Super-South Bridge: Lift cargo cult 0xe0-0xef noprw (machine\i82371sb.cpp)
  . S3 86C988 ViRGE/VX: Added virgevx_pci stub. Hookup Leadtek WinFast 3D S600DX BIOS alt to virgedx_pci (pci\virge_pci.cpp)
  . S3 86C325/75 VGA core: Added stub Serial Port implementation and retire s3virgedx_rev1_vga_device (video\s3virge.cpp)
  . Samsung S3C24xx: Fixed Clang 20.1.0 erroring due to using memset on non-trivial objects (devices\machine\s3cXXXX.cpp). Got rid of a layer of indirection on LCD bitmaps (machine\s3c24xx.hxx).
  . Taito TC0080VCO/TC0100SCN/TC0480SCP: Mark gfxram dirty after loadstate
  . Zilog Z80C30 SCC: Reassert interrupt if conditions persist (machine\z80scc.cpp). Fixes (MESS) x68000 [metlunit, metluni2]: Reaction on mouse use is only partial (ID 09141).
- cdi.cpp
  . Renamed matte flag constants and refactored matte handling code. Renamed "regions" to "mattes" to match Green Book convention (philips\mcd212.cpp).
  . Fixed handling of transparent layers and simplified code. Only execute the first matte that triggers on an X coordinate. Ignore transparent layers when mixing. Show the backdrop when both layers are transparent (philips\mcd212.cpp).
- ddragon.cpp: Increase overall ADPCM volume. Fixes broken music and too low sound effects volume in Double Dragon (World set 1) and clones (ID 07947).
- ddragon3.cpp: Small cleanup to source code spacing (technos\ddragon3_v.cpp)

- mcatadv.cpp: Cleaned up code: Use sign extension and bit extraction helpers. Avoid unnecessary device replacement in machine configuration. Made more variables const and updated comments.
- model1/2.cpp: Write the results of an ALU operation before writing to register/memory. Sega Rally has an instruction that calculates d += p and loads a value into d at the same time; it is the loaded value that should be used, not the result of the ALU operation. Also only test the d register when performing an ALU operation (mb86233\mb86233.cpp).
- mystwarr.cpp: Small cleanup
- neogeo.cpp: Correct link MCU rom label. Updated documentation

  . Identified 'Draw Poker HI-LO (unknown, rev 1)' as Sure Shot. Added custom palette, buttons-lamps layout, inputs and machine config for Sure Shot. Added a default NVRAM and buttons-lamps layout and derivated inputs for 'Fast Draw (poker conversion kit)'.
  . Promoted dphl, dphla, dphljp, dphlunkb, drhl, drhla, fastdrwp, norautua, norautub, smshilo, ssjkrpkr and sureshoto to working.

- Renamed (dphlunka) to (sureshoto), (drw80pkr) to (drw80wld), (drw80pk2) to (drw80pkr), (kovqhsgs302) to (kovgsyx), (mrwoo) to (mrwoou) and (multchmp) to (multchmp25)
- MAME
  . VIDEO RENDERING SYSTEM
    . Remember last partial updates reset time because of scheduler time travel issue. Fixed possible race condition at reset_origin if vblank start == vblank end (emu\screen.cpp).
    . Make 'Qiji 6 (V118CN)' show the attract demo (emu\emupal.cpp)
    . Bulk replace screen_update suffixes and m_rotatingsprites -> m_sprites (tatsumi\*)
  . UI/OSD: Added newline at end of -version output (mame\clifront.cpp)
  . CHD/CHDMAN: Hacked around GitHub #13029 (issues creating delta CHDs). The code depends on getting away with trying to read at least one hunk past the end of the parent CHD. Previously it just ignored any errors from reading the parent CHD, but adding error checking broke it. This hack just ignores that specific error. Also cleaned up some gross flow control and made more things const. The code should obviously be fixed properly, but that's non-trivial. This gets it to a state no worse than it was in 0.270. Use a C++17ism to reduce if nesting a bit (util\chd.cpp).
  . 3rdparty
    . Updated to LUA 5.4.7 and expat 2.6.4. Added dummy expat_config.h to hopefully fix macOS buid (3rdparty\expat\lib\expat_config.h).
    . Removed unused global LITTLEENDIAN/BIGENDIAN macros, as well as TRUE/FALSE macros (3rdparty\softfloat\mamesf.h and softfloat\milieu.h).
  . Consolidate driver into single file (esd16.cpp and simpl156.cpp)
  . MiniMAWS: Set option strict for JavaScript code (scripts\minimaws)
  . Removed spurious spaces with name and supported values for consistency (hash\*)
- SDLMAME: Nothrow is passed to operator new, not to reinterpret_cast. Pass in explcit alignment to operator new just in case (osd\modules\file\posixfile.cpp).
- Fixed some things causing save states to be unportable: Don't save block stride as it depends on alignment rules (emu\save.cpp). Don't send display orientation to machine outputs (windows\winmain.cpp).
- Fixed paper size selection for building MAME PDF documentation. Also set paper size to widespread A4 for dist.mak and CI (github\workflows\docs.yml, dist.mak and docs\Makefile).
- Recursively discover device types when filtering output. Don't waste time/memory collecting device types when not filtering. Added null check (mame\infoxml.cpp).
- VGM player: Give visual feedback for playing/paused and loop state (virtual\vgmplay.cpp)
- Compiling
  . Bail if no argument specified (scripts\build\check_include_guards.py)
  . Sort driver projects and sources within driver projects to give more determinisitc output on filesystems that don't enumerate in order by filename (e.g. XFS or ext) (scripts\target\mame\mame.lua).
- Debugger
  . Added option to disable window grouping. Option is in debugger console window Settings menu. Changes apply on hard reset or restarting MAME. Setting is saved to default.cfg (debugger\win\*).
  . Changed "Exception Points" to "Exceptionpoints" in the debugger documentation and help. This better matches "Watchpoints" and "Registerpoints". Also, it's very confusing that you see the help topic listing showing "Exception Points" but typing "help Exception Points" doesn't actually work (debugger\exceptionpoint.rst).
