Genesis8
Abalore just released his latest project, no more no less than a newémulateur multi platform Amtrad CPC emulator, but only compiled for Linux at the moment. It do not support CPC+ but can read .CPR cartridge and run Alcon 2020 for example.

Amstrad CPC CRTC Compendium v1.9 by Longshot (May 2026) and his blog
-
Genesis8
Longshot has released version 1.9 of the Amstrad CPC CRTC Compendium (15th May 2026) which is a documentation about the CRTC 6845 (and some others circuits). Note that the CRTC is a generic component used in several computers including the IBM PC.
It is possible to check if an emulator is good with the SHAKER tests by Longshot. SHAKER is a program designed to run on CPC machines produced by AMSTRAD in the 80s-90s. The objective of this program is to carry out extensive tests on the video circuits of this machine. These video circuits are the GATE ARRAY and the CRTC 6845. AMSTRAD produced several series of GATE ARRAY and used CRTC models produced by different manufacturers (HITACHI, MOTOROLA, UMC, AMSTRAD). This has been causing compatibility problems on operations that exceed the functional specifications of these circuits. The identified CRTCs are numbered from 0 to 4.
And last, if you like reading, don't hesitate to go check Longshot's blog.
PicoZ80 by Engineers@work, a replacement of the Z80 processor

Genesis8
The PicoZ80 by Engineers@work is un replacement of the Z80 using a Raspberry Pico 2. It features a faster CPU, more memory (ROM/RAM banking), virtual devices, networking (WiFi, BT thanks to an ESP32), rapid application loading from SD card and WiFi management.
It is possible to configure the PicoZ80 with a .JSON file to adapt to the host machine, already working for the Sharp MZ-700 (and later for the MZ-80A, MZ-80B, MZ-800 and other Sharp computers). The author want to also to provide a profile for the Amstrad PCW. So I think it isn't impossible to make one later for the Amstrad CPC.
A 128 Kb to 1 Mb Amstrad cartridge for CPC+/GX4000 by Eto
The weather is gloomy, with no sun at all. There's not much joy left in your heart, but maybe I have the solution for you: just watch the video the Amstrad CPC for Noobs by Nicolas PREIRE below, and maybe a ray of sunshine will appear behind you.
Interview by Felisuco of Mark Eric Jones, the engineer of the Amstrad CPC and PCW (and a bonus)

Felisuco has made at the start of October 2025 an interview of Mark Eric Jones who is one of the engineer of the Amstrad CPC and PCW. The interview is in spanish but as usual there is a translation possible on Youtube.
Abatape by Abalore, tape emulation featuring multi loading on Amstrad CPC and more
-
Genesis8
Abalore has a project he is working since September 2024 : the Abatape.
It is using an Arduino Nano ATMega328p@16 Mhz, a 700 mAH battery for about 24 hours of use, a SD reader and an OLED screen. It is especially able to detect the two motors making a real taping moving the magnetic band so it can support multi loading. Someone did suggest to add writing support to create new tape files. The Abatape supports of course the Amstrad CPC (.CDT) but several other computers as it is based on a Maxduino firmware :
Spectrum : TAP, TZX
MSX : CAS, TSX
ZX80 : O
ZX81 : P
Acorn Atom, Electron : UEF (without compression), TSX
Dragon 32/64, Tandy CoCo : CAS, TSX
SVI Spectravideo : TSX
Oric 1/Atmos : no .TAP support unless converted to TSX
