![]() ![]() dmg extension and running truncate -s 819284 your_image.dmg to produce a Disk Copy image. ![]() Note, you'd be wise to use lsar on the file first as Macintosh files contain characters like spaces rather commonly and unar does not provide an option to rename the output file during extraction.Īt this point I recommend renaming or copying the. If the image is wrapped in BinHex, we can use The Unarchiver's unar/ lsar to unpack the file. ![]() We'll address that first since it's far more common. sea self-extracting disk image, possibly with a BinHex (. It will be either a Disk Copy image (819284 bytes) or a. However, if the image you are using comes from Apple, it will not be raw. Just fdformat the floppy device for 1.44MiB as you would for any other DOS/Windows/Linux machine and write the image using a command like, dd bs=512 if=floppy_image.img of=/dev/floppy If the image you're using is a raw image (819200 bytes exactly, often used by emulators, that's easy. Yes, Windows (still) uses FAT12 as the default file-system for floppy disks.Here's what I've been able to determine: A short filesystem on a floppy should work fine, as long as the blocks are in the right order.

What exactly is the meaning of “IBM formatted” and what is theĭespite what some may think, in the past, much software was ported to most of the available platforms (which was a pretty big feat since there were so many back then, but without the benefit of cross-platform, portable code frameworks).Īpplication programs were often cross-platform, but cross-platform games were even more common. I have often come across floppy disks in the past that were marketed ![]()
