This was the golden age of dedicated utilities. Programs like Copy-Tape (from Your Computer magazine), Lerm (short for “Lerm’s Excellent Replicating Machine”), and Trans Express emerged. These worked by:
As software became more complex, so did the methods used by publishers to protect their intellectual property. The "arms race" between software houses and copy utility developers became a defining feature of the mid-to-late 1980s. Developers implemented "speed loaders" and custom header formats to bypass the standard ROM loading routines, making simple copy tools obsolete. In response, copy software evolved into sophisticated "bit-copiers" and "nibblers." Programs like "SoftCopy" and the legendary "Lerm" series were designed to read the raw pulses from the tape, ignoring the logic of the data and simply replicating the magnetic patterns. These tools often included features to "crack" protection schemes, such as finding and disabling the code that checked for specific timing intervals or hidden data blocks. zx copy software
