Many games (Ocean, Ultimate, Hewson) wrote their own loading routines instead of using the Spectrum's ROM loader. Copy software had to:
Place the original card on the device's induction area and click Start Decoding in the software. zx copy software work
These systems used precise timing loops. The game would check if a certain routine executed in exactly X microseconds. Copy software worked by emulating the tape loading routine inside its own code, then patching the game to skip the timing checks. Many games (Ocean, Ultimate, Hewson) wrote their own

But what exactly does this phrase mean today? How did copy software actually function on such limited hardware? The game would check if a certain routine
