Jiffydos-c64.bin

JiffyDOS for the Commodore 64 is a fast DOS replacement ROM that dramatically speeds up disk and serial-device access by replacing slow, handshaking-based routines in the C64/1541 I/O firmware with a high‑speed protocol. "jiffydos-c64.bin" is the binary ROM image for the C64 side of that system (the other half typically runs in a peripheral like the 1541-II, a modern SD2IEC device with JiffyDOS support, or in a fitted 1541 drive ROM).
