MacOS is a lot bigger then the ROMs in a game console.
Yes, in principle you could write an emulator which emulated every aspect of the target platform's OS and could run programs without requiring a disk image. Without that OS, the emulator is lacking the resources required to run any programs. So you can do the same trick.) However, a Macintosh is a *computer* with a disk-based operating system, just like Windows XP runs on a computer, and needs to boot from a hard disk before it can run any programs. (Likewise, since you mention it most Amiga games were self-contained on a boot disk. That makes is relatively simple to make an emulator that lets you double-click a file and 'just run it'.
A game console emulator doesn't need an OS image, because everything not part of the console is already on the disk image, ROM image, whatever. You're comparing 'Apples and Oranges', so to speak. MacProgram.extensionwhatever on a winxp without the need to installĪn entire MacOs like what we do in pearPC Then what is the name of this emulator that makes me run a: I dont have a mac!!so.dmg are archives.ok!!
