Default Floppy Disk or Hard Drive Image
When launching into a core that uses virtual disks, you might desire to have a system disk or other favorite disk pre-mounted, especially if the OS requires a certain disk to be present to continue the boot process. To use this feature, simply name your disk image “boot.vhd” and copy it into your core’s subdirectory.
Default BIOS ROM or Cartridge ROM
Some cores might require a special BIOS ROM, DOS ROM, BASIC ROM, etc. to be present to continue the boot process. To use this feaure, simply name your ROM image “boot.rom” and copy it to your core’s subdirectory.
