If you get "Not Ready" or "Drive A: Insert System Disk," your boot order is wrong—the emulator is still looking for a floppy. Disable the floppy drive in the config.

Originally, the X68000 relied on 5.25-inch floppy disks. Playing a masterpiece like Akumajō Dracula (Castlevania) meant constant disk swapping and long load times. For years, emulation was a headache because you had to manage hundreds of individual .dim or .xdf files. The Solution: The HDF Format

: Similar to the "eXoDOS" projects, this is a highly curated, metadata-heavy set designed for easy use in front-ends like LaunchBox.

: The HDF must be formatted with Human68k (v3.02 is standard). The sys c: command is required to make the image bootable after copying the system files.
