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.
- Home folders are now read from that list, instead of extracting them from the CONF_STR.
- 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.

games affected by fixes:
- Internal Section
- Final Fantasy Tactics
- Primal Rage
- Simple Series Billard
- Alien Resurrection
- Grandia
- Aconcagua

fixes/changes:
- emulated justifer: implemented offscreen trigger mode for both offscreen shooting and using triangle button
- emulated justifer: implemented irq on/off command so that 2 players with justifiers are now supported
- emulated justifer: adjusted screen mapping to better match what games expect
- CD: don't stack up cd sectors when XA is playing
- CD: queued up IRQs will not be handled instantly anymore after old IRQ is cleared by CPU
- CD: increases pause waiting times to min values of psx spx documentation
- CD: fix bug where pending drive response would fill 3 slots in response fifo
- CD: on read after seek, keep seek status bit active until read status bit is set
- Video: store paused values instead of live values in savestate
- Video: corrected odd/even bit timing for both 240p and 480i content
- SNAC: Select fix, remove initial delay, cleanup, clk gen only done when port is active now
- GPU: add drawing area and offset to softreset
- SPU: repeat ignore also when voice is off
- SPU: always transmit written data so data fifo will get empty
- fixed a bug that could lead to wrong values being cached when using Turbo

accuracy improvements:
- Video: set hblank sample point significantly before end of line(fulfill HW test)
- Video: generate Hblank timer from video out statemachine, but instead of hblank for video/scaler also during vblank
- 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.

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.

Fix mouse sensitivity when used as a paddle
Fix virtual lightgun not working when "crop overscan" is enabled
Improve virtual lightgun accuracy and add horizontal tuning option
Add option to allow some quirky usb to paddle adapters to have both paddles on the same controller (READ THE README)
Add support for new 7800 "Bankset" mappers (power of two sizes only)
