Basilisk II is described as 'Open Source 68k Macintosh emulator. That is, it allows you to run 68k MacOS software on your computer, even if you are using a different operating system. However, you still need a copy of MacOS and a Macintosh ROM image to use Basilisk II'. There are six alternatives to Basilisk II for Windows, Linux, Mac, Android and iPhone. The best alternative is AppleWin, which is both free and Open Source. Other great apps like Basilisk II are MESS (Free Personal), Mini vMac (Free, Open Source), PCE (Free, Open Source) and Sheepshaver (Free, Open Source).
MESS emulates portable and console gaming systems, computer platforms and calculators. The project strives for accuracy and portability and therefore is not always the fastest emulator for any one particular system.
The Mini vMac emulator collection allows modern computers to run software made for early Macintosh computers, the computers that Apple sold from 1984 to 1996 based upon Motorola's 680x0 microprocessors. The first member of this collection emulates the Macintosh Plus.
