![]() Mini vMac emulates compact Mac models (such as the Macintosh Plus, although it also supports models from the 128K to Classic. BasiliskII is mostly more ambitious, because their driver replacements actually *do* allow things like SCSI and Serial ports to work, at least to a limited degree. There are three main classic Macintosh emulators: Mini vMac, Basilisk II and SheepShaver. vMac also plays tricks with "faking" things like mouse emulation by directly poking into system registers instead of emulating the raw hardware, so their approaches really aren't that different. ![]() The most optimistic thing it tries to do is emulate the sound hardware (which is really primitive and nasty in a Mac Plus), with mixed results. Last I checked vMac mostly just emulates "stubs" for things like serial ports and SCSI so it perpetually looks like there's nothing attached. I suppose in principle one could reduce startup time by a few milliseconds if you rewrote the code to persistently cache the patched version but I've never seen that.Īlso note that vMac "emulating" hardware is a pretty optimistic way to describe it. The ROM file on the drive is the plain binary image pulled straight off the Mac. BasiliskII just goes further and hacks the video/audio/network drivers as well. Basilisk II- The best free GNU Mac emulator, emulating the Mac IIcx through the Mac. Both emulators replace the ROM floppy driver with their virtual disk driver. E-mail sheepmyshaver123- For any fan mail, requests or questions. (Or, in the case of running newer OSes, with a New World ROM image.)Īlso note that the main reason BasiliskII and vMac can't use the same ROM image is because vMac normally emulates 68000-based machines (it *does* have a limited MacII emulation mode now as well) while Basilisk *solely* emulates a 32-bit clean MacII or Quadra.Īnd, also, technically speaking, vMac also patches the ROM. Both Mini vMac and SheepShaver are far superior emulators, though Basilisk II does fill the hole between 7.5 and 8.5 which some vintage software requires. (It doesn't like Powerbook, Quadra AV, or Quadra 580/630-family ROMs.) Same goes for Sheepshaver, which will run with varying degrees of success with ROM files from most beige PCI Power Macs. Basilisk does only work with a limited selection of Mac ROMs and some work better than others (most people use a 1MB ROM from a specific Performa model and that is often linked off the howto sites) but that selection does include most 32-bit-clean Mac II family, LC, and Quadra ROMs. Yes, they do heavily patch the ROM, but they do it at runtime.
