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This core has been superseded by Atari 7800 core. 2600 repository disabled from further updates and now is read-only.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.

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.

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:
