Notes¶

MAME requires a number of BIOS and device files, place in the bios folder in zip format. Boot disks are from MAME's software lists, floppy images need to be extracted and renamed. It is recommended to use a hard drive option if available, System 6.0.8 if not. From mac_flop: macos3.img = sytem tools.img from sys30.zip macos608.img = system tools.img from sys608.zip From mac_hdflop: macos701 = disk tools.img from sys701.zip macos75 = SSW750_DiskTools.img from sys75.zip From mac_hdd: mac601.chd, mac701.chd, and mac755.chd lr-minivmac requires MacII.ROM and MacIIx.ROM. If booting from a hard drive, floppies may not load at boot. For best results, make a copy of one of the bootable drives, load disks manually via the MAME menu, and copy or install them to the hard drive image. Disk images will only load on Mac IIx and are not bootable.
