Updated the ZX Spectrum emulator - Fuse.

Emulation core improvements:
 - Expand automatic tape-loader detection and acceleration for Microprose, Software Projects, Gremlin 2 and Movieload loaders
 - Improve automatic tape playback for custom loaders, letting Basil the Great Mouse Detective, Viz: The Computer Game, Moonlighter and Trzy Wymiary load without manual tape control
 - Fix accelerated loading of Bomb Jack and similar loaders
 - Avoid accelerating the Technician Ted loader
 - Do not automatically restart rewound tapes at end of tape, making it easier to change sides in multi-side games such as Echelon
 - Handle bare tape flag blocks explicitly, improving compatibility with unusual tape images
 - Restore tape-loading sounds for beeper machines
 
Machine specific improvements:
 - Support both 8K and 16K Interface 1 ROM images, preserving their size in snapshots
 - Enable DISCiPLE on 128K machines, with inhibit behaviour and an exposed magic button in widget UIs
 - Correct +D address decoding for more accurate peripheral behaviour and software compatibility
 - Remove the beeper capability from Timex machines, their amplified beeper sounds different
 
User interface improvements:
 - GTK3: restart the fullscreen autohide timeout so menu and status bars respond immediately
 - GTK3 and SDL2: set the correct application identity so Linux desktop environments display the proper Fuse icon
 - Correct CAPS SHIFT handling when multiple host cursor keys are held
 - Show pulse counts for RLE Pulse blocks in the tape browser
 
Scaler improvements:
 - Improve the composite scaler, with better performance and colours correctly extended to the screen edges
 
RZX improvements:
 - Fix RZX playback desynchronisation from EI-delayed interrupts, letting affected recordings replay without desynchronising
 - Reproduce some Spectaculator CPU behaviour and +D snapshot paging, SPIN 0.5 frame-boundary and tape-save input quirks, and the R register from recordings made before Fuse 0.7, letting more recordings play correctly
 - Handle legacy Spectaculator Scorpion Z80 pages in Z80 snapshots
 - Place autosave snapshots after interrupt processing so unfinalised recordings can restart correctly in other RZX players
 - Report missing snapshots and compatibility warnings more clearly, making playback failures easier to diagnose
 - Fix the --playback command-line option so RZX playback can again be started from the command line
 
Debugger improvements:
 - Allocate Pokefinder working memory only when it is needed

A developer known as LackofTrack has released an unofficial port of the classic Super Mario Bros. from NES/Famicom to the 8-bit Sega Master System. The project also includes new graphics and sound modes that leverage the hardware capabilities of the SMS.

Near-perfect Accuracy: The game plays almost exactly like the original. While I cannot guarantee perfect accuracy, I feel confident that the port is accurate under normal gameplay.

New Graphics Mode: The port introduces a new graphics mode based on the SNES/SFC port of the game in Super Mario All-Stars/Super Mario Collection. Savor the pseudo 16-bit graphics with more color, backgrounds, and style!

New Sound Mode: The port also introduces a new sound mode that takes advantages of the YM2413 FM synthesizer found in the Japanese Sega Master System and commonly added to systems through aftermarket modifications. This new sound mode's music is based on the music in Super Mario All-Stars/Super Mario Collection. Immerse yourself in the rich, 16-bit style arrangements!
 - Requires a console with a YM2413.
 - The Sega Mark III's FM Sound Unit is not compatible with this mode.

Updated the ZX Spectrum emulator - Fuse.

- Improve ZX Spectrum ULA beeper emulation with separate MIC and speaker paths and improved speaker-response modelling
- Automatically select the appropriate speaker response for each emulated machine, with universal manual overrides
- Preserve snapshot peripheral ROMs across soft resets and correct Multiface ROM handling after a machine reset
- Improve tape trap accuracy, including correct handling of short ROM blocks and ROM flag comparisons
- GTK3, SDL2 and Win32 UIs: coalesce dirty display areas per frame to reduce redundant scaling and presentation work
- Reduce display dirty-tracking memory usage and improve its address decoding
- Avoid rereading startup media files and improve Windows distribution dependency handling
- Expand display, scaler, snapshot, Pokefinder and Z80 disassembler test coverage, including MinGW builds
- Various minor bugfixes and cleanups

The PC-Engine / TurboGrafx-16 - Ootake emulator has been updated.

- The sound volume balance has been adjusted to more closely match the real hardware
- Added "Early games Use Old System Card" to the CD-ROM menu. Among the early CD-ROM2 titles released before the launch of the Super CD-ROM2, games that appear to have been developed for System Card v1.0 will automatically boot using the older system card (the one set as Old System Card). If you do not have an image file of v1.0, please uncheck this option
- Added "Arcade0 Stretched" to the Screen menu. In the 256-pixel horizontal mode, the display uses an aspect ratio that provides dot-by-dot(1:1 pixel mapping) rendering. Unlike "Non-Stretched", black bars appear on the left and right sides. For games that operate in modes of 320 pixels or wider, the image will be displayed slightly narrower horizontally compared to "Arcade1 Stretched"
- Added "Auto Aspect Ratio (Gradius II with Arcade0 Stretched)" to the Setting->Improve menu. When playing "Gradius II" with the Arcade0 Stretched display mode, only the PCE-exclusive opening and ending scenes are shown using the pixel aspect ratio of Real Stretched instead of dot-by-dot (1:1 pixel mapping)- -- Fixed an issue in the opening visual scene of "Cosmic Fantasy" where the ship graphics were not displayed correctly. The sprite rendering limitations of the original hardware are now properly reproduced
- Fixed an issue where a game installed from CD could not be recognized correctly after its game title was renamed, if the new name contained certain full-width characters such as "ソ"
- Corrected the game title recognition for the following CD-ROM titles:
 - "Yokoyama Mitsuteru Sangokushi (J)"
 - "Yokoyama Mitsuteru Shin Sangokushi (J)"
 - "Kagami no Kuni no Legend (J)", and ""Ultra Box Soukangou (J)"
If save data from an older version cannot be loaded due to the game title change, please manually rename the save data file. After saving once, you can confirm the new file name
- Various minor issues have been fixed and improvements have been made
