Download a "base HDF" (OS only, no games) from archive.org, then use xdfcopy or dim2hdf scripts to add games.

In the context of emulation and modern flash-cartridge hardware, an HDF file is a raw byte-for-byte image of a hard disk drive.

Widely considered the gold standard for accuracy, this closed-source Japanese emulator is the top choice for purists. Setting up an HDF involves going to "Tools" -> "Options" -> "SASI" (or SCSI), enabling the drive, and pointing the emulator to your .hdf file.
