New Computer Core: Homelab
Homelab was a series of Hungarian KIT computers in the 1980s invented by József Lukács and Endre Lukács.

MiSTer conversion by JasonA, HTP support by Flandango

Distribution repo:
- Using the new Cores Wiki page (https://github.com/MiSTer-devel/Wiki_MiSTer/wiki/Cores) as the source of truth to retrieve the list of cores.

- Download script reimplemented in python.
- Fixed bug that inserted NVRAM.dat file in Coleco games folder (file is now removed).
- Fixed bug that caused the omission of APPLE-I and PDP1 files and folders.
- Using authentication token in GitHub API call to avoid rate limit issues.
- Additional metadata support for tags in the DB calculator step.

ao486:

- Add CPU rating presets (newsdee, spark2k06, me).

Note: it's very approximate rating and doesn't provide cycle accuracy. Depending on specific application it may run either faster or slower than advertised rating.

Tomy Tutor:
- Support for Cartridges with RAM
- Fixed CPU bug that caused some graphic glitches
- Added Video Cropping to remove top and bottom borders (not 216p though)

- Timer: reset TMR0 on falling HBlank instead of rising HBlank

Distribution repo:
- Improved filtering for MGL files and top folders by including the folders related to such content. For example, using the term !mgl will remove not only all MGL files but also all the associated 'games' and 'docs' folders. Or using !computer will do the same for all computer folders.

Menu:
- updated framework.

Main:
- ini option to disable autofire.
- Use names.txt for MGL and MRA as well.

New Arcade Core: Slap Fight / ALCON (Anton Gale)

XSleena
Core update:

• Unified core using dynamic PLL reconfiguration to adjust the speed to the pixel video clock for support different video modes (57.4Hz and 60.0Hz).
  Many thanks to Martin Donlon aka @WickerWaka for helping me to understand how this works.

• Added a Hacks menu to alternate CPU speed between 1.0x and 2.0x turbo mode.

You need to update both rbf and mra files.

New console core: BBC Bridge Companion

The BBC Bridge Companion was a console dedicated to teaching the game of bridge, released in 1984. It's features included:
- 12 buttons on the console (so you'll need a keyboard for this, please check the README for key bindings)
- 9 official software titles (they are all built in to the core, use the Cartridge option in the menu to change)
- No sound!

- Love&Destroy
- all Code Monkeys video-puzzle games, e.g. Animal Football, Dalmatians, Dinosaurs

fixes/improvements:
- GPU: allow full 512 pixel height and 1024 pixel width in framebuffer mode(480p hack now allows 512i->512p content)

- CD: clean up CD command handling in respect to pending IRQ
- CD: add current sector time when going into pause
- CD: limit maximum seek time, even if seek was done while other command was still pending
- DMA: stretch CD DMA data transfer to real PSX values

PCXT:

- XTIDE ROM update: Updated with the Full Operation Mode option enabled, it is now compatible with the BASICA application and some other Tandy 1000 software that might be incompatible with this mode disabled. Thanks @akeley for investigating this problem.

Note: This update is about the SW folder of the GitHub repository, to take advantage of it you must rebuild the ROMs with the corresponding scripts located inside the same directory.

PCXT:

- PCXT31 and Micro8088 ROMs updated: Updated with the Full Operation Mode option enabled, it is now compatible with the BASICA application and some other Tandy 1000 software that might be incompatible with this mode disabled. Thanks @akeley for investigating this problem.

Note: This update is about the SW folder in the GitHub repository, to take advantage of it you must replace the ROMs of the games/pcxt folder in MiSTer with these, which contain the embedded XTIDE BIOS.

Main:
- Added Michael Simone's Y/C module to template.
- Add control for Y/C output.
- Fixes in HDR (Sam Hardeman).
- Improve single BIN PSX image handling (zakk4223).
- video: default preset and reset option (Martin Donlon).
- Support for disk routines of C128 core (Erik Scheffers).
- Support to use mouse wheel as spinner (Matheus Fraguas).

Note about Y/C output:
1) All cores will need update. They will be updated soon.
2) CVBS output is done through green channel (with Sync-On-Green enable option/switch). There are several ways to get CVBS (composite). a) through vga_mode=cvbs INI option, but voltage level is lower than CRT TV expects, so you may get dark video depending on your TV. b) through vga_mode=svideo and connect green and red outputs together. It will give a better voltage output. c) using external mixer/amplifier board to get a proper output.
CVBS also has dot crawl issue, so to workaround it, yc.txt file should be placed to the same location as MiSTer.ini which includes manually adjusted parameter for each core.
3) S-Video uses green as luma and red as chroma signals.

Menu, NES, SNES, NeoGeo:
- NES: support for keyboard (greyrogue).
- Updated framework.

Minimig:
- RTC: support for seconds (fixes RTC in Workbench 1.3).
- Updated framework.
