Create a destination folder on your system that you will install MAME in.The latest versions for Windows, OSX and linux can be found on MAME’s site. Exit Mame and write or copy the initialized blank.cdd image file to your target media.Run Mame and Initialize your image file using the patched version of: HD SC Setup 7.5.5 or Drive Setup 1.5 or Drive Setup 1.7.3.Use DD or some other similar tool to create a image of your physical drive, SD card, CF card or other media and rename to blank.cdd (or whatever you want).Download my 2GB System 7.5.5 drive image and rename to mac755.chd.
For this blog entry I’m going to walk through setting up MAME to emulate a Macintosh Plus with the assumption your using MAME instead of Basilisk II because you want to initialize and partition an image file that you created from a physical drive, SD card etc. Most people use it to emulate old arcade systems and gaming consoles, but it also provide support for several of the 68k Macintosh Systems (search the page for mac.c). You likely already know what MAME is, but if not, the simplest description is a multi-purpose emulator.
