These last years several expansions allows you to use mass storage (USB or sd...) on Amstrad CPC, each needing a ROM to use it correctly.

And if you use two of these expansions, you will need to load two ROMs, so less RAM for your Amstrad CPC.

So Offset did write UniDOS and drivers to be able to use another expansion, needing only one ROM with features being the same whatever the expansion. Unidos can manage actually :

• Albireo by PulkoTronics
• M4 Board by Duke
• X-Mass by Tot0
• Symbiface II by Dr.Zed
• Nova by PulkoTronics

Offset also wrote UniDOS Cartridge Creator (v1.4) which is an utility to create Amstrad Plus cartridges equipped with a patched firmware which allows to add UniDOS and its DOS nodes. You can furthermore configure up to 30 additional tool ROMs (such as Utopia, Maxam, Protext..) in the cartridges (compatible with ParaDOS and Burnin' Rubber) without requiring a real ROM board. The tool also let you automatically download the latest UniDOS ROMs from the official web site.

Unidos v1.51 is a minor release released in September 2024, which is only fixing the|COPY RSX so that it also works properly with weird binary headers generated by some PC tools.

New versions by Roudoudou of his RASM Z80 assembler v2.2.9 and of his ACE-DL Amstrad CPC emulator (10/26/2024) :

• Dandanator goes to Basic mode without cartridge to avoid side effects
• new button in Machine configuration to reinit the entire machine (no plugin, no rom, no breakpoints)
• import of natives ACE breakpoints from RASM symbol file
• may click Timer in Trace to reset nop counter
• may press F7,F8,F10 when trace mode but focused on another window
• added HOME/END and Shift+HOME/END in memory explorer to navigate in memory and selection
• more persistence for CRTC register value change
• update also RASM to benefit direct import of native ACE breakpoints

Caprice Forever v2024-10 by Frédéric Coste is a modified version of the Caprice emulator (by Ulrich Doewich) for Windows (32/64 bit) and also a 2022-06 for Windows XP.

New version yesterday by Roudoudou of his ACE-DL Amstrad CPC emulator.

After downloading the emulator, you can also get a SymbOS disk image or OPL3 music to be used with the Willy OPL3 plugin.

ESPectrum is a ZX Spectrum emulator for the boards Ilygo TTGo VGA32 and Olimex ESP32-SBC-FabGL. There is now since a few an Amstrad CPC emulator named CPCESP, with a 3D printed packaging by Jose Lopez (other photos). The first software version of CPCESP was released the 7th July 2024 on Github. You can find CPCESP on :

• CPCESP on Facebook
• CPCESP on Twitter

Olivier Poncet is the author of an Amstrad CPC emulator : Xcpc v0.52.0 for Linux, BSD and Unix. It doesn't emulate the + models though.

He is talking about how to write an emulator on his web site.

And also quite interesting, he has released last month AYM JS which is a sound chip emulator written in JavaScript emulating the AY-3-8910 PSG (Programmable Sound Generator) and the YM2149 SSG (Software-Controlled Sound Generator). You can test AYM JS here (press the Power button and the Play button). At the moment YM files must be converted to javascript (but the conversion tool isn't available yet), but direct support of YM files is on the way.

Caprice Forever v2024-06 by Frédéric Coste is a modified version of the Caprice emulator (by Ulrich Doewich) for Windows (32/64 bit) and also a 2022-06 for Windows XP.

RetroVirtualMachine v2.1.15 by Juan Carlos González Amestoy is available since the 14th June. It's an Amstrad CPC emulator (and more computers) for MacOS, Windows and Linux.

• Windows
• Raspberry pi (raspbian)

Longshot has released version 1.8 of the Amstrad CPC CRTC Compendium (8th May 2024) 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.

dMagnetic v0.37 by Dettus is available since May 2023 for several versions of Unix (BSD, Ubuntu, Debian, Gentoo) with ANSI drawing in a terminal. This utility lets you play adventure games by Magnetic Scrolls.
