Single-Board Computers / Raspberry Pi

LibRetro / RetroArch is used as the foundation of Lakka, Recalbox, Batocera and RetroPie alternative OSes for the Raspberry Pi and other SBC. But you can also use RetroArch for Amstrad CPC emulation on a stock Raspberry Pi OS. Or you can use these stand-alone CPC emulators:

Mass-storage

Emulator support for mass-storage expansions is as follows:

Dobbertin Harddisc is emulated by MAME
uIDE is emulated by Arnold
Symbiface II IDE/PATA interface or compatible (X-Mass, Cyboard) is emulated by ACE, Caprice Forever, MAME, WinAPE, WinCPC, Arnold, Virtual CPC
Albireo is emulated by ACE, Caprice Forever
M4 Board is emulated by CPCemu
Vortex Winchester Drive, USIfAC / ULIfAC and Symbiface3 / RSF3 are not supported by emulators

CPC cartridge slot

Emulator support for a CPC cartridge slot is as follows:

Dandanator brings a non-standard physical cartridge port and a very exotic non-standard memory mapper that spies on Z80 instructions (sacrificing compatibility without any justification). It is emulated by ACE, Retro Virtual Machine, CPCEC, ZEsarUX, DSP
Plus2CPC brings a standard physical Plus cartridge port to the CPC. It is not supported by emulators
Play2CPC is an evolution of the Plus2CPC, adding RMR2 Plus mapping, R/W cartridge support, CRTC cursor raster interrupt and a 3-channel soundchip conforming to the PlayCity base spec. Play2CPC is emulated by ACE
M4 Board simulates a standard Plus cartridge port on the CPC and handles standard CPR files. M4 Board is emulated by CPCemu

Audio devices

Emulator support is as follows:

SSA-1 speech synthesizer is emulated by ACE, Caprice Forever, JavaCPC, MAME
Dk'Tronics speech synthesizer is emulated by ACE, Caprice Forever, JavaCPC, MAME
Techni-Musique speech synthesizer is emulated by ACE, Caprice Forever
Amdrum is emulated by ACE, JavaCPC, MAME, WinAPE
Digiblaster is emulated by ACE, Caprice Forever, JavaCPC, MAME, WinAPE, CPCEC, CPCEPower, WinCPC, Virtual CPC
PlayCity is fully emulated by ACE, MAME, Arnold, SugarBox. The audio part of PlayCity is emulated by Caprice Forever, JavaCPC, CPCEC
Play2CPC implements the PlayCity base spec (aka Arcade Sound System). It has one additional soundchip instead of two and no CTC chip. It is emulated by ACE
Willy OPL3 is emulated by ACE
Willy MIDI is emulated only by ACE for Haiku
Music Machine, Speak&SID, LambdaSpeak, Amsdap (SE-One, Moonsound, etc...) are not supported by emulators

Rewind feature

ACE-DL has a rewind feature, but it is not as good as it could be: Demonstration of rewind in ACE-DL

At the moment, only the RetroArch CPC emulator has a proper rewind feature: Demonstration of rewind in RetroArch. To reverse the game, the user press and hold the rewind button. And at any point, releasing the button makes time goes forward again.

A very simple approach would be to make a SNA for each frame and limit the RAM snapshot to 128KB, which is ok for 99% of CPC software. For a 10-seconds long rewind functionality, only 64MB RAM is needed (128KB * 50 frames * 10 seconds).

A more efficient approach is to store only the values that are changed in RAM between two frames, so that RAM can be restored when rewinding. This allows for long-rewinds, even of a CPC equipped with a 4MB RAM expansion. Proof of it is the GBA emulator SkyEmu demonstrating super long rewind while needing very few RAM.

For debugging, going back to the previous instruction is easily implemented. The emulator has to store the time when the previous instruction was executed so that he can go back to that instruction. In the same way, emulators can provide access to the previous HBL, IRQ, VBL, etc.

Emulator Detection

If you want to promote usage of real CPC computers, you can detect CPC emulators by:

Checking if the memory is initialized with zeroes, as real machines have random memory values at boot
Focusing on the minute details in Z80, CRTC and PPI chips. They are most often wrong in emulators
Examining the FDC chip. It is only replicated more or less superficially in all emulators because the internals of the chip are still unknown

Combining these methods will definitely get you a 100% success rate in detecting emulators, even the toughest ones.

Emulator undetected
Emulator detected

There is also this initiative for emulators who willingly want to be detected: Emulator IDs
