For home computers (Amiga, Atari ST, MSX, ZX Spectrum), the (The Old School Emulation Center) standard applies. MiSTer packs for these often include .adf (Amiga Disk File) and .hdf (Hard Disk File) images that work seamlessly with the Minimig core.
Unlike software emulators, the MiSTer FPGA ecosystem requires specific, often meticulously named and version-matched ROM files (especially for arcade cores). “Mister Rom Packs” (often found via Internet Archive, GitHub, or private trackers) are curated collections that bundle BIOS files, console ROMs, and arcade ROM sets (e.g., MAME 0.270 or Update All-compatible) into a drag-and-drop folder structure for SD cards or USB drives.
