Hardware and Parts


Peripherals support

Mass storage devices

Emulator support is as follows:

Audio devices

Emulator support is as follows:

Graphics devices

CPC graphics display expansions (CRTC Type 5, Amsdap GFX9000) are not supported by emulators.

CPC graphics acquisition devices (Dart Scanner, VIDI digitizer, Digitaliseur Ara) are not supported by emulators.

CPC printers are poorly supported by emulators. The only emulators that at least do some print rendering emulation are JavaCPC and Caprice Forever.

Input devices

Some lightguns / lightpens are emulated by ACE, ACE-DL, Caprice Forever, JavaCPC, CPCEC, CPCEPower, Virtual CPC, Wiituka.

CPC mouse support is as follows:

Note: AMX and MultiPlay are the most widely supported mice in CPC programs

Hacking devices

Emulator support is as follows:


Rewind feature

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

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.

  • CPC DiAG also shows that the primary colours themselves are a bit different. Blue is more vivid and Green is less fluorescent on Amstrad displays.
  • Colours are less saturated and black is not as profound on CRT monitors than they are on modern displays.

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
  • Playing with the "floating" bus. Using Z80 read I/O commands to write to chip registers. Using undocumented I/O ports. Writing to multiple chips simultaneously
  • Focusing on the minute details in Z80, CRTC, PPI and PAL 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. Many emulators don't even support the FDC SCAN or FORMAT commands

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

  • Emulator undetected in Open Tower Defense

  • Emulator detected in Open Tower Defense

Additionally, an Emulator IDs system is available for easier detection of CPC emulators.

On ZX Spectrum, gamedevs are challenging emulators real hard with titles like MEMPTR Snake and Chromatrons Attack
