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.

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.

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

- 9 official software titles (they are all built in to the core, use the Cartridge option in the menu to change)
- No sound!

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.

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.
