Atari 2600:

This core has been superseded by Atari 7800 core. 2600 repository disabled from further updates and now is read-only. All further bug fixes and improvements for Atari 2600 should be made in Atari 7800 core which is fully compatible with 2600. Also 7800 core has improvements in 2600 part. All supported mappers are automatically detected and don't require special file extensions. So simply rename them back to standard a26 or bin extension.
Atari 2600 core still can be downloaded manually from its repository in its current form.

Tatung Einstein TC01
+ new computer core

Tatung Einstein TC01
+ Added video mixer and updated sys to support shadow masks, etc.

Downloader:
- Version 1.4 released.
- Added support for custom download filters: Users can now avoid installing files that they are not interested in. More info here: https://github.com/MiSTer-devel/Downloa ... filters.md
- Fixed makedirs errors.
- Improved backup handling when a file is downloaded but the hash is wrong.
- Option url_safe_characters introduced (which is used aturllib.parse.quote(safe)).
- Better logging for update_only_linux and update_linux=false.
- Output is stored in the correct order in the logs when a Linux Update happens.
- Custom databases can now trigger sleeps through its header property.
- Better log when a file has override protection and could be updated.
- Other general improvements: optimizations, more test coverage, code cleanup...

CoCo3
CoCo3_220124.rtf Updates:
1: Fully supports CoCo3_FPGA / GIME-X byte move transactions (GART) via addresses $FFE1-$FFE9 [see docs].
2: Fully supports CoCo3_FPGA / GIME-X font manipulation [see docs].
3: Cold Start implemented new approach. The fixes the problem of going from Disk Basic to Extended Basic and not seeing a
difference. The change has side effect of not being able to cold start out of OS9. Work-around: <ctrl><alt><ins> followed by
<ctrl><alt><del>.
4: Memory size now supports 16MB. New OSD control allows the memory selections of 512K, 1M, 2M, and 16M.
5: New OSD option to 'Force Turbo' mode. If set the OSD turbo mode speed settings always control the coco's clock rate.
6: Tons of code cleanup including closer alignment to GIME-C and CoCo3_FPGA code. Better Cart compatibility.
7: MPI selection in the OSD has changed. Orch90 has been removed [you can load it as a cartridge or disk]. The selections are
(Slot 3) ECB and (Slot 4) Disk.
8: RTC has been added via addresses [$FFC0 - $FFC7] - [see docs].
9: New 'Force Turbo' mode is OSD.

Tatung Einstein TC01
+ You can now switch to the Einstein 256 in OSD

PMD85 core update
+ MHB8251 implemented (i8251 clone, games use it as a timer and TxD and RxD signals are now connected to MiSTer user port = you can communicate from PMD85 MiSTer core to PC now)
+ All RAM implemented (games like Hlípa and Magicland Dizzy works now)
+ eprom range decoder fix
+ interface 8255 chip select fix

Introducing MT32-pi lite for MiSTer

This is simplified version of MT32-pi board. It uses Raspberry Pi Zero 2W. It doesn't have any buttons or displays and very compact. It sits firmly on the side of the case. It also doesn't use cable, so it has more stable connection.

More info you can find here:
https://github.com/MiSTer-devel/Hardwar ... 32PiHat_LT

Release gerbers are in usual place:
https://github.com/MiSTer-devel/Hardwar ... r/releases

Main:
- Add UEF tape converter for BBC/Acorn cores (alanswx).
- input: calibration menu/save/load for GunCon 2 (Nolan Nicholson).
- PSX: add encryption map generation using markun's code.
- x86: fix ide flags.

CoCo2
+ fixed CoCo disk support
+ dragon disk support is there, but doesn't work quite right

Main:
- Adaptive scanlines support by Wickerwaka (cores will be updated to support this feature).
- IDE: Set default block size for multi r/w (Alex Oughton) (fixes Linux boot in ao486 core).
- PSX: change saves handling. Now memory card 1 is automounted per-game (like other cores).
- PSX: auto-pick cue/iso if only one available in folder and other tweaks/improvements.
