Rewind feature

The RetroArch CPC emulator has the most convenient rewind feature: Demonstration. To reverse the game, the user press and hold the rewind button. And at any point, releasing the button makes time goes forward again.

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

One 128KB snapshot per frame allows 10 seconds of rewind with 64MB (128KB * 50 frames * 10 seconds) of memory for the rewind feature. A more efficient method saves only the previous RAM values that are changed between 2 frames, allowing much longer rewinds (even if the CPC is equipped with 4MB RAM expansion) while using less memory, as shown by the GBA emulator SkyEmu.

For step-back debugging, the emulator just needs 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 initialised with zeroes, as RAM in real machines is not initialised during boot. Source
Configuring the CRTC to stop refreshing part of the RAM. This behaviour has never been emulated. Source

The way to cause the RAM refresh to fail in both a Plus or normal CPC is simply to stop a few bits of the CRTC address changing (ie. never refresh the selected area).
Generally, only the Row address needs to be cycled, so stopping MA0 through MA7 from changing, and stopping the CPU from reading those rows, will cause data to be lost, quite quickly (generally around 4ms).

Playing with the "floating" bus. Using Z80 read I/O commands to write to chip registers. Accessing ghost registers. Using undocumented I/O ports. Writing to multiple chips simultaneously. Changing PPI and PSG ports direction.
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 TRACK commands.

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

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, Super HALT Invaders Test and Chromatrons Attack.
