- CPU
  . Dynamic Re-Compiling
    . Fixed various recompiler issues and added functionality:
      . Added BREAK, SETFLGS, MULSLW and MULULW opcodes. Limit range of immediate shift count arguments for consistency. Fixed simplification of multiplication and division operations (cpu\uml.cpp).
      . Added more methods of accessing OP_CARRY. Fixed flag calculation for BSWAP and MULS opcodes. Made calculation for shift and rotation opcodes consistent. Return mapvar register ID instead of value for mapvars (cpu\drcbec.cpp).
      . Fixed bugs in various opcodes to make them behave like the C backend (cpu\drcbex86.cpp and cpu\drcbex64.cpp). Fixed SAVE, RESTORE and SETFMOD (cpu\drcbex64.cpp).
      . Implemented MULLWx and MULLWOx using the new MULSLW opcode (powerpc\ppcdrc.cpp).
      . Clear top half of iregs on loads to I0-I3, fixed LOADS sign extension and fixed FLOAD/FSTORE data size (cpu\drcbex86.cpp). Use appropriate register size for LOAD (cpu\drcbex64.cpp).
      . Fixed parameter sizes for READM/WRITEM and clear upper half of registers after 32-bit operations (cpu\drcbec.cpp). Fixed definition for FSREAD/FSWRITE, FDREAD/FDWRITE and READM/WRITEM simplification (cpu\uml.cpp).
      . Make uml::is_param_out a member function and really fix build error (cpu\uml.h)
      . Added a 64-bit ARMv8 (AArch64) DRC back-end (cpu\drcbearm64.cpp). Use saved return address from stack for op_recover. Handle landing pads save the LR/FP pair, so the return address for the first level of callh, exh or "no code" handler can be recovered from below the base frame pointer (cpu\drcbearm64.cpp).
      . Removed unused vector type (cpu\uml.cpp). Fixed crash with LOG_HASHJMPS enabled (stack needs to be 16-byte aligned before calling debug_log_hashjmp_fail) (cpu\drcbex64.cpp).
      . Moved member function resolution code to a common location (util\mfpresolve.cpp). Use common member function resolution code (util\delegate.cpp, cpu\drcbex64.cpp and cpu\drcbearm64.cpp).
      . Moved some stuff to anonymous namespaces (cpu\drcbex86.cpp, cpu\drcbex64.cpp and cpu\drcbearm64.cpp). Defer allocating labels if they aren't always needed (cpu\drcbex86.cpp and cpu\drcbex64.cpp).
      . Calculate NZ flags for shifts/rotates by 0 bits (cpu\drcbec.cpp, cpu\drcbearm64.cpp, cpu\drcbex64.cpp and cpu\drcbex86.cpp). Fixed flag calculation for 64-bit multiplication when result is zero (cpu/drcbex86.cpp).
      . Be nicer to the return address predictor (cpu\drcbex64.cpp). Give hints to use short displacements for jumps to local unbound labels (cpu\drcbex86.cpp). Use references for some things that must not be null pointers (util\mfpresolve.h).
      . Added write byte with explicit mask. This wasn't added to the DRC implementations when it was added to the address space classes (cpu\drcbe*.cpp).
      . DRC cleanup and minor optimisation: Build all native back-ends if any native back-end is enabled so errors caused by changing interfaces can be found faster. Moved resolved member function stuff to a place where it can be shared by back-ends (cpu/drcbeut.cpp). Use ubfx instruction to extract unordered flag (cpu/drcbearm64.cpp). Bypass trampolines when calling get map variable value and debugger instruction hook functions (cpu/drcbearm64.cpp, cpu/drcbex64.cpp). Moved some internal helpers that don't need to be members to anonymous namespace (cpu/drcbearm64.cpp). Added a comment with some info to help when debugging generated code (cpu/drcbearm64.cpp). Put code in the drc namespace (cpu\drcbec.cpp).
      . Slight DRC code generation optimisation: Consider a RIP-relative LEA for generating 64-bit values (7-byte instruction versus a 10-byte MOV instruction). Seems to work pretty well for heap pointers (cpu\drcbex64.cpp). Changed the near cache base pointer offset from 0x80 to 0x100.  The value 0x80 was copied from the x86-64 back-end where it was choses to allow an 8-bit signed displacement to reach as much of the top of the near cache as possible. However, AArch64 use 9-bit signed displacements, so a quarter of the range was being wasted. cpu/drcbearm64.cpp: Consider an adrp/add sequence for generating immediate values as well as memory references (cpu\drcbex64.cpp).
      . Fixed off-by-one errors in map variable handling (cpu\drcbearm64.cpp and cpu\drcbec.cpp)
      . Fixed ADRP usage. ADRP output must always be an X register. Tidy up some stuff (cpu\drcbearm64.cpp).
  . hyperstone E1-32XN: Removed workarounds for recompiler backends not clearing upper half of I0-I3 on 32-bit load (e132xs\e132xsdrc_ops.hxx)
  . IBM PowerPC
    . PowerPC 601 has POWER and PowerPC instructions, allow both in disassembly. Strip the debug info (powerpc\ppc.h, ppc_dasm.h and ppccom.cpp).
    . More support for the 601's POWER/PPC dual nature, including several POWER instructions (powerpc\ppc*).
  . Intel 8085A: Correct some variable types
  . Intel 8086: Don't clear physical irq pins state at reset (i86\i86.cpp)
  . MCS-51
    . Fixed P3.1 output logic. Mode 0 is still incorrect. Update savestates. Don't mask P3.1 at reset. Added some TODO notes (mcs51\mcs51.cpp).
    . Implemented PES bit for DS5002FP. PES bit is peripheral enable select on bytewide bus. Improved execute_run icount timing. Max opcode cycles is 4 (mcs51\mcs51.cpp).
    . Removed unneeded powerdown check. Removed old changelog from comments and copypasted comment block. Clean up source code spacing (mcs51\mcs51.cpp).
  . Motorola MC6800: Added dummy read to CLR opcode (m6800\6800ops.hxx)
  . Motorola MC68000: Fixed disassembly of CAS (m68000\m68kdasm.cpp)
  . RCA CDP180x: Fixed load init phase (cosmac\cosmac.cpp)
  . Texas Instruments TMS57002 'DASP': Fixed input sample overflow
- SOUND
  . HC-55516: Correct variable type of digital sample in hc55516 class. Small cleanup. BTANB NOTE: Outputs a low-volume but very high-pitched background tone when /FZ is active and the hardware doesn't have a low-pass filter.
  . ZOOM ZSG-2: Update stream before reading
- DEVICE
  . Brooktree Bt481 RAMDAC: Implemented RAMDAC with hardware cursor (video\bt48x.cpp)
  . Floppy
    . Removed code supporting functionality that's no longer used. Eliminated floppy_get_drive_type and floppy_set_type. No callers for these functions allowing us to get rid of the FLOPPY_TYPE_ defines as well. Drop flopimg_get_image, floppy_drive_get_next_id, floppy_drive_read_track_data_info_buffer, floppy_drive_write_track_data_info_buffer, floppy_drive_format_sector, floppy_drive_set_index_pulse_callback, floppy_drive_get_current_track_size, floppy_wtd_w  floppy_wpt_r, floppy_dskchg_r and floppy_twosid_r. Drop flopimg_get_sectors_per_track and flopimg_get_id_callback. Drop unneeded state variables: m_id_index and m_rdy. Make some members as private (imagedev\flopdrv.cpp).

- MAME
  . VIDEO RENDERING SYSTEM
    . Cherry-pick Wayland improvements from upstream BGFX. Properly support Wayland under EGL and Vulkan. Dynamically load libwayland-egl.so.1 when dealing with Wayland to remove dependencies at program startup. Support both X11 and Wayland in the same build: Works for both Vulkan and OpenGL. Removed --with-wayland from genie options. Vulkan loads all three extensions for surface creation instead of only one. Added width and height parameter to GlContext::createSwapChain(), which is needed for EGL to create a SwapChain with the given window size. Dirty-fix the example-22-windows to recreate the FrameBuffer by first destroying and then recreating to make sure the window is released of its swapchain. Fixed dbgText glitch in example-22-windows. Removed old X11-related dependencies for GLFW3. Adapt to latest bgfx wayland code. Fixed Vulkan swapchain invalidation issue. Always clamp render pass to frame buffer size. Fixed formatting. Hopefully fix macOS build (3rdparty\bgfx\*, osd\sdl.lua, osd\sdl_cfg.lua and render\drawbgfx.cpp).
    . Mark gfx ram dirty after load state (emu\digfx.cpp)
    . Account for flipped tilemap in get_info_debug (emu\tilemap.cpp). Fixes tilemap viewer doesn't account for screen flipx x/y when hovering mouse cursor over tiles (ID 09067).
  . DEVICES: Round scaled clock to nearest integer (emu\device.cpp)
  . LUA engine: Expose mame_ui_manager::show_menu() to LUA (mame\luaengine.cpp)
  . UI
    . Don't rescale icons that are close to the target size (ui\selmenu.cpp)
    . Make inc/dec slider control consistent with other sliders where holding ctrl = 'big steps'
    . Use a smoother, symmetrical highlight texture (ui\widgets.cpp) (ID 09095).
  . INPUT: Fixed enum range warnings in debug builds (interface\inputcode.h)
  . PLUGINS: hiscore.dat update (plugins\hiscore\hiscore.dat)
  . 3rdparty: Updated AsmJit to latest upstream (3rdparty\asmjit)
  . Set_clock_scale takes a double, not a float (cps2.cpp, backfire.cpp, deco_mlc.cpp, konamigx.cpp, segas24.cpp and littlerb.cpp)
  . Updated copyright years to 2025 (docs\source and language\*). Rearranged README.md sections and updated links. Updated brief instructions for compiling with Visual Studio. Added repobeats activity graphs. Linked CI badges to workflow pages (README.md). Removed obsolete reference to MESS.
  . Removed "all rights reserved" copyright comment (src\*)
- Compiling
  . Don't treat K&R function definitions as an error. Some AArch64-specific code in C/CpuArch.c uses () when it should be using (void) (lzma; src\3rdparty.lua).
  . Disable command line string escaping, fixes MAME 0.273 incorrect paarsing SDL_INI_PATH directive and build faild #13150.
  . Adjust MSVC warning settings (scripts\genie.lua and scripts\src\3rdparty.lua)
  . General: Housekeeping and MSVC warning elimination. Avoid potential unsafe use of bool and empty controlled statements. Annotate some unused variables. Removed some undefined functions (i386\i386segs.hxx, machine\arm_iomd.cpp, ui\prscntrl.cpp, tools\nl_convert.cpp, igs\igs_m027.cpp, namco\namcos22_v.cpp and namco\namcos23.cpp).
  . Deal with NUL when osd_uchar_from_osdchar uses mbstowcs (osd\strconv.cpp)
  . Added constexpr to the bitswap with explicit count. This was a hangover from poor implementation of constexpr in older compilers (util\coretmpl.h).
  . Added helper for getting CPU cache line size (cpu\drcbex86.cpp, drcbex64.cpp, lib\osdlib_macosx.cpp, osdlib_unix.cpp, osdlib_win32.cpp and osd\osdcore.h)
  . Added libfontconfig-dev in preparation for Ubuntu 24.04 (github\workflows\ci-linux.yml)
  . Added missing standard library headers (util\corestr.cpp and sound\sdl_sound.cpp)

- CPU
  . ARM7 CPU: Added Intel StrongARM SA-1100 variant (arm7\arm7.cpp)
  . Dynamic Re-Compiling
    . Optimised load/store and call generation. Removed fallback to static address space accessors. Removed static trampoline fallbacks for get map variable value and debugger instrcution hook functions. Added scaffolding for directly dispatching memory accesses. Optimised immediate value generation. Detect immediates that can be generated with a single movz/movn/orr. Prefer adr over add to base register (no register dependency). Don't bother trying to load base register value from memory. Got rid of loop in check for contiguous mask values. Slightly optimised generation of ROLAND/ROLINS shift counts. Further optimisation: Recognise immediate values that can be generated using a movn with shift 16 or an orr immediate into a W register. Recognise repeating patterns that can be represented as a bitmask immediate value. Slightly optimised generated code for UML AND when at least one argument is immediate zero. Added optimised UML AND code when the instruction size is 8 but the second argument is a valid 32-bit bitmask immediate. Shuffled RECOVER instructions a bit to be nicer to the CPU's scheduler (cpu\drcbearm64.cpp).
    . Don't use static address space accessors. This gives a big performance improvement. Removed static trampolines for get map variable value and debugger instrcution hook functions (cpu\drcbex86.cpp).
    . Made failure to resolve address space accessors fatal. Removed static address space accessors. Don't allocate from the DRC cache unnecessarily. Allocate label helpers and map variable changes from the process heap. They're only used during code generation and have no business being in the DRC cache. Keep map variable changes contiguous, don't deallocate label helpers and map variable changes on completing a block. Got rid of simple_list, more const, tidied a little (cpu\drcbeut.cpp).
    . Don't use goofy X64_WINDOWS_ABI macro, just check _WIN32. The only other environment that uses the Windows calling convention is (U)EFI, and we can move feature detection to util/abi.h if we ever need to care about it. Removed fallback to static address space accessors. Fixed regression in FWRITE. Removed static trampoline fallbacks for get map variable value and debugger instrcution hook functions. Correct stack diagram in comment. Directly dispatch memory accesses no larger than native width to specific handlers. Fixed handling of address map global mask. Fixed Final Furlong failing to boot. Slightly optimised some degenerate cases for memory accesses. This gives a very small improvement for systems with 32 address lines and no global address mask (e.g. pmac6100, sf2049 or coolmini). Shuffled RECOVER instructions a bit to be nicer to the CPU's scheduler (cpu\drcbex64.cpp).
    . Moved some member function pointer manipulation stuff into the library. Gives another slight reduction in the size of libemu (util\mfpresolve.cpp).
    . Moved DRC backend declarations out of headers and into anonymous namespaces
  . Motorola MC68000: Added missing set_current_cpu function (m68000\m68000.cpp)
  . MIPS-III: Removed static address space accessors. All they were doing was hurting performance (mips\mips3.cpp)
  . NEC uPD7725: Prevent out-of-bounds reads (upd7725\upd7725.cpp)
  . Philips SCC68070: Limit external memory addresses to 24 bits, fixes (MESS) cdi:zombie and clones and possibly others (m68000\scc68070.cpp).
  . RCA CDP180x: Added pull callbacks for int/dmain/out (cosmac\cosmac.cpp)
  . Sony CXD8xxx: Added a delay after SPU DMA is triggered to prevent a lock up in Pocket Racer and Primal Rage II test mode & improved logging (psx\dma.cpp).
- SOUND
  . FM core: Sync to latest (3rdparty\ymfm). Apparently there is no internal flag when latch was written. OPNA does not have 4 latches (3rdparty\ymfm\src\ymfm_opn.cpp). Actually emulate opl2 waveform enable bit. No need to check for IsOpl2Plus here (3rdparty\ymfm\src\ymfm_opl.h).
  . MSM5232: Cleaned up some inconsistent formatting (sound\msm5232.cpp)
- DEVICE
  . ATA
    . Abort ATA commands when writing to command block registers and DRQ or BSY is set, which is mentioned in the ATA3 specification as a possible outcome. Removed the equivalent hack used by the cojag games. Improved the logging in the ATA code. Don't abort commands if the drive/head register is written with the current value (machine\atahle.cpp). Reading the status doesn't acknowledge interrupts unless BSY is 0, update RDY when reading either cs0 or cs1, log the correct device number even when device 0 is standing in for device 1, don't log data reads/writes if the device isn't selected, fixes regression that prevented slave devices working. Fixes regression in 'Tropical Chance' booting and 'Psyvariar -Revision-' save settings, by reverting to ignoring writes when BSY flag is set (machine\atahle.cpp).
    . ATA-1 specification says that some drives will de assert interrupts if there is more data to be read (machine\atastorage.cpp)
  . ATAPI: Store sense key in ATA error register (ata\atapihle.cpp). Attempt at implementing unit attention how software needs it to be rather than any standards and removed ATAPI_FIXED_CDROM & ATAPI_FIXED_DVDROM (ata\atapicdr.cpp, firebeat.cpp, hrdvd.cpp, mtouchxl.cpp, namcos12.cpp and stingnet.cpp).
  . ATAPI CD/DVD-ROM and SCSI CD/HD: Fix for 'Tropical Chance' booting since MAME 0.272 (machine\t10mmc.cpp) by setting the correct media type. Added support for mode sense dbd flag & mode select shouldn't use the length in the header.
  . Cassette tape image: Prevent regression in cass images. Put allocation outside loop again and check more allocations for failure (formats\cassimg.cpp).
  . CD-ROM: Fixed wrong track number in error messages (util\cdrom.cpp)
  . Centronics: Hookup The Adaptator DE-9 multitap device (centronics\ctronics.cpp). Register a possible DDR variable (centronics\adaptator.cpp).
  . Cirrus Logic GD54xx: Rectify linear addressing enable (video\pc_vga_cirrus.cpp)

  . K001006 Texel Unit: Cleaned up code. Suppress side effects for debugger reads. Use bit helpers, made some variables constant. Derive from device_palette_interface for palette. Throw a fatal error if the texture ROM size is not a supported size. Match texture data size to texture ROM size (konami\k001006.cpp).
  . K001604 2D tilemaps + 2x ROZ: Fixed max palette numbers of gfxs (konami\k001604.cpp)
  . K037122 2D Tilemap: Fixed max palette numbers of gfxs (konami\k037122.cpp)
  . K051733 Protection: Suppress side effects for debugger reads, use logmacro.h logging and cleaned up code (konami\k051733.cpp)
  . K053936 Video Controller: Correct source/destination parameter order to alpha blending function. Also moved blending tests inside the loop (video\k053936.cpp).
  . K055673 Sprite Generator: Improved sprite blending (konami\k053246_k053247_k055673.cpp). Minor K053247_device::zdrawgfxzoom32GP cleanup: Moved variable declarations closer to use. Use appropriate variable types. Mark applicable variables as const. Moved "cull off-screen objects" early out check earlier in function. Moved back "dst_" vars under appropriate comment. Further reduce reuse of "eax" variable. Use cliprect directly inside function. Renamed various "eax" variables. Simplify switch-case to if statement (konami\k053246_k053247_k055673.cpp) (konami\k053246_k053247_k055673.cpp)
  . Z80 DMA Controller: Suppress side effects for debugger reads (machine\z80dma.cpp)

- dec0.cpp: Lower OPL2 volume. Fixes difference in Bad Dudes music of MAME 0.236 and PCB (ID 08116).
- ddenlovr.cpp 
  . Improved DIP switch settings for Mahjong Daimyojin
  . Fixed credit limit settings for Mahjong Daimyojin and Hanafuda Hana Ginga. The credit limit is multiplied by the coin rate for these games.
  . Added DIP switch definitions for Hanafuda Night Rose. Game is still marked not working due to game-breaking emulation issues similar to Hanafuda Hana Gokou.
- fortune1.cpp
  . Big improvements to Video Poker/Fortune I driver: Changed driver name rom videopkr.cpp to fortune1.cpp, being the most significative hardware. Hooked mechanical counters to all games. Added hopper support to all games. Changed the parent/clone relationships. Hooked the new CPU and therefore all the functions. Added NVRAM support to the MSC51 family. Worked the 8155 connections.

- After Burner: Make 'prequel' a parent set
- After Burner II: Correct DIP switch settings
- Air Rescue: Prevent out-of-bounds reads in the upd7725 cpu core
- Ali Baba and 40 Thieves: Added debugger side effects check
- Amiga (alg.cpp, arsystems.cpp, cubo.cpp, mquake.cpp and upscope.cpp)
  . Misc popmessages aimed at AGA unsupported stuff (amiga\amiga_m.cpp)
  . Added vblank line mechanism for penalties (amiga\agnus_copper.cpp)
  . Trigger an irq if channel DMA gets disabled during playback (amiga\paula.cpp)
  . Amiga AGA: Removed intermediate misprint. Hookup bplam for single playfield mode. Hookup bplam for single playfield mode. Implemented pf2ofx color table. Fixed playfield-sprite collisions. Implemented CLXCON2 and palette reads (amiga\amigaaga.cpp).
  . Hookup 8-bit NVRAM device (amiga\cubo.cpp)
  . TOD is not latched when CRB_ALARM is set (MOS8520; machine\mos6526.cpp)
- Battlantis: Actually emulate opl2 waveform enable bit (ymfm\src\ymfm_opl.h). Fixes music sounds wrong in Battlantis after the MAME 0.231 OPL rewrite (ID 08391).
- Beastorizer: Beastorizer (USA bootleg) was not listed as promoted to working, so assume the "not working" flag was removed inadvertently
- Captain Lucky: Added 6809 sound CPU. Some ROM and RAM is mapped, based on Sigma B52 sound CPU map. Communication is not hooked up.
- Cow Tipping: Fixes for MC68EZ328: Allow selection and use of Port A: On EZ and VZ, PASEL is reserved, and it was hard-coded to 0 (disabled). However, the user manual notes: "In an 8-bit-only system, you can configure these pins as a parallel I/O port by writing a 1 to the WDTH8 bit of the SCR". According to the MC68328 datasheet, something similar should be needed to activate its Port B, but that change is not included here. Its PBSEL is exposed, so there is likely no difference in emulation. Fuller implementation of timer: The existing implementation left the timer counter (TCN) at zero until the compare value (TCMP) was reached. However, some software relies on reading the TCN values to measure elapsed time. The timer counter (TCN) now increments on every timer tick (machine\mc68328.cpp).
- Fruit Bonus 2010: Added default NVRAM and correct dips
- GameCristal and Games Family: Pull up non-existant COM3 access (machine\sis950_lpc.cpp)
- Gauntlet Legends: Correct button labels. Fixes gauntleg, gauntleg12, gauntdl and gauntdl24 "Fight" and "Magic" button labels are reversed (ID 09100).
- Gratia: Fixed roztiles file names to match PCB silkscreen
- Hana Doujou: Added proms hookup and sketchy video emulatio. Improved colors and pinpoint service DIP. Preliminary IOX HLE devices (seta\iox_hle.cpp). Inputs improvements and patch protection check 1. Hookup NVRAM and identify a couple service inputs.
- Juno First and Tutankham: Cleaned up code. Increased main CPU ROM region size to fix out-of-bounds accesses in some banks. Reduced sound CPU ROM size to match area mapped in address map. Made some variables const and reduced preprocessor macros (konami\junofrst.cpp and konami\tutankhm.cpp). Use a device finder array for audio filters (shared\timeplt_a.cpp).
- Konkyuu no Hoshi: Tweak some of the sound clocks
- Mega Drive (hshavoc.cpp, megadriv_acbl.cpp, megadriv_sunmix.cpp, megaplay.cpp, megatech.cpp and puckpkmn.cpp): Hook up z80 busrq pin (sega\megadriv.cpp)

- Mini Vaders: Cleaned up code. Restrict drawing to clipping rectangle, reduced literal tag usage and improved member names.
- Mole Attack: Reduced unrealistic 6502 clock
- N-Sub: Dumped PAL for clone N-Sub (cocktail)
- Nibbler: Removed BAD_DUMP flag and fixed bits comment for ic10 in Nibbler (rev 9, set 2). ROM passes test and the fixed bits comment simply isn't true.
- Operation Wolf: Added support for Taito TC0060DCA volume control and hooked up to Operation Wolf. Updated stream before setting level (taito\tc0060dca.cpp).
- Othello: Timer dipswitch was wrong way around. Tweak sound clocks. Fixes BGM Plays at double speed and higher pitch (ID 09122).
- Phozon, Shanghai (Japan) and Zaxxon (set 2, unknown rev): Dumped PLDs
- Quick & Crash: Dumped correct dotcpu rom for clone Quick & Crash (US)

- The Simpsons: Cleaned up code. Reduced literal tags and run-time tag lookups and use more descriptive tags.
- Sliver: Minor cleanups and added some notes
- Space Invaders / Qix Silver Anniversary Edition: Fixed position offsets when screen is flipped and restrict drawing to clipping rectangle. Use BIT helper to extract bits. Reduced literal tags and redundant code. Improved member names.

Added workaround to unmask the inputs for the gambling mode. Redefined the interrupt system. Documented all the different modes and features. Documented the reverse-ingeneering done to get all the modes working. Documented the inut system through reverse-engineering. Modded the coin-in input, now tied to the PIA6821.
- Tutankham: Cleaned up code. Increased main CPU ROM region size to fix out-of-bounds accesses in some banks. Reduced sound CPU ROM size to match area mapped in address map. Made some variables const and reduced preprocessor macros (konami\tutankhm.cpp). Use a device finder array for audio filters (shared\timeplt_a.cpp).
- WWF Superstars: Removed old changelog, note about scrolling (it's same as pcb), scrollregs trampoline and obsolete vblank hack. Fixed palette OOB access.
- Wyvern F-0: Cleaned up code. Use memory share creator to allocate banked RAM. Use explicitly sized types for member variables that need to be saved. Reduced literal tags, run-time tag lookups, redundant code and unnecessary variables.

- Renamed (cameltry) to (cameltryu)
- MAME
  . MEMORY SYSTEM
    . Got rid of static accessors structure and added a helper for obtaining info for dispatching specific accessors (emu\emumem.h and emu\emumem_aspace.cpp)
    . Moved some member function pointer manipulation stuff into the library. Gives another slight reduction in the size of libemu (emu\emumem_aspace.cpp).
