Originally developed by Creative Micro Designs (CMD), JiffyDOS is a replacement for the Kernal ROM in your C64 and the DOS ROM in your disk drive (such as the 1541 or 1571). Unlike software-based fast loaders, JiffyDOS is built directly into the computer's operating system, providing a permanent and highly compatible speed boost. Key Benefits

The “bin” in your query likely refers to a —a raw program or data file—while “hot” might indicate a technique such as “hot loading” (loading without resetting the computer) or a cracked/scene release label. In the context of JiffyDOS, binary files benefited the most from the speed increase because they transferred as pure data without the overhead of BASIC tokenization.

If you are using an emulator like VICE , you can load the jiffydos64.bin file to emulate the enhanced ROM:
