Note thatthe ROM image file is copyright Apple Computer, and may notbe redistributed. A program such asвЂњ CopyRomsвЂќ,when run on a real Macintosh Plus, will savethis information to a file, which can then be transferredto the computer on which you want to run Mini vMac. So Classic only works on Tiger if running on PowerPC hardware or in a PowerPC emulator like QEMU.The ROM (вЂњRead Only MemoryвЂќ) contains information needed forthe Macintosh Plus to function, and the emulation of theMacintosh Plus also needs this information. Rosetta lets you run software written for PowerPC OS X if you're on an Intel Mac with OS X up to Snow Leopard. Classic lets you run software written for Classic MacOS if you're on a PowerPC Mac with OS X up to Tiger.

Power SwitchWhen Mini vMac launches, it will look for a ROM image file in a numberof possible locations. There are only a few bytes different in version 2 from version 1, to fix a bug where the Macintosh Plus wouldnt boot if an attached SCSI devices was not turned on. The original (and rare) version 1 ROM was recently reported not to work, presumably because of problems with SCSI emulation. It is a system that has been received positively in an environment that is otherwise filled with controversies, which put in question the very idea of the PS4 game being able to be emulated on a PC or not.Versions 2 and 3 work with Mini vMac. PS4Emus is one of the Top PS4 emulators for PC out there. If you donвЂ™t have a Macintosh Plus,you could check theвЂњ Where to buy an old MacintoshвЂќpage.PS4 Emus best ps4 emulator for Mac.

On Windows you usea 'вЂњShortcutвЂќ' file. The emulator is able to emulate a Mac Classic or Mac II depending on the Mac.Before giving up and asking you where the ROM image file is,the first location Mini vMac will look for it is in the foldercontaining the MinivMac application, with the name вЂњvMac.ROMвЂќ.The ROM image file may also be placed elsewhere, with an alias(named вЂњvMac.ROMвЂќ) to it placed in Mini vMacвЂ™s folder.'Alias' is the term used for Macintosh. Once you have told Mini vMacwhere the ROM image is, booting will resume.OS9exec - execution environment for OS-9/68k user-mode programs on MacOS9. Or, in the Macintosh or Windowsversions, you can choose the вЂњOpen Disk Image.вЂќ commandfrom the вЂњFileвЂќ menu,or the вЂOвЂ™ command from the Control Mode to bringup the bring up the standard dialog. You can drag the icon of the file ontoto the Mini vMac window.

If Mini vMac doesn't find theROM image in the locations described above, it willalso look in a specific central location. Or, if there is an argument ofthe form вЂњ-d вЂќ, MinivMac looks for the ROM image in. Actually, the file is really namedвЂњvMac.ROM.lnkвЂќ internally, but what you see is вЂњvMac.ROMвЂќ.)And in the X versions you use a symlink, or 'symbolic link'.An exception to the above is that in the Mac OS X version,if you create a folder called вЂњmnvm_datвЂќinside the вЂњContentsвЂќ folder within the application bundle(control click on the application and choose вЂњShow Package ContentsвЂќ),then Mini vMac will look for the вЂњvMac.ROMвЂќ file, and the disk1.dsk, disk2.dsk, etc files,within the вЂњmnvm_datвЂќ folder.This allows you to make a self contained Mac OS X application thatruns an application for the Mac Plus (especially when used with theвЂњ AutoQuitвЂќsoftware.)In the X version, if the folder containing the application can not bedetermined, Mini vMac looks for the ROM image file in the current directory.For example, finding the application directory is not implementedin OpenBSD and Minix.Also in the X version, if an argument of the formвЂњ-r вЂќ is used on the command line,that is used instead of the application directoryor current directory.

Mini vMac does notcheck if the ROM image file is too long (it should be 128K =131072 bytes).There are three different versions of the Macintosh Plus ROM.Versions 2 and 3 work with Mini vMac. Sinceno harm can be done no matter what is in the ROM, this is onlya warning, and Mini vMac will keep running. Thereis code in the ROM to do this when the Macintosh Plus boots,but since Mini vMac patches the ROM to replace the disk driver,it also patches the ROM to disable the checksum verification.So Mini vMac does the check itself, before patching the ROM,and gives a warning message if the checksum is incorrect.

Mini vMaccanвЂ™t tell if the emulated operating system has been properlyshut down, but it can tell whether any disk images arecurrently mounted, and so uses that as the test for warnings.If no disk images are mounted, Mini vMac can be quit withControl-Q, or by clicking in the close box of the Mini vMacwindow, or with the quit command in the menu(Macintosh/Windows).If a disk image is mounted, clicking in the close box orchoosing the quit command in the menu will bring up a warningdialog. Justlike with the real computer, you should shut down the operatingsystem running within the emulated computer first. There are also many other ways of launchingapplications for each operating system, such as by installingit into the dock of Macintosh OS X, the Apple menu ofMacintosh OS 9, or the start Menu of Windows.Off: Quitting the Mini vMac application is liketurning off the power switch of the emulated computer. Double click on theapplications icon to launch Mini vMac in Macintosh or Windows.The application can be launched from the command line in Linuxand Windows. There are only a fewbytes different in version 2 from version 1, to fix a bug wherethe Macintosh Plus wouldn't boot if an attached SCSI deviceswas not turned on.On: Launching the Mini vMac application turns on thepower switch of the emulated computer.

Alternatively, Mini vMaccan be compiled with full read/write support for this format.Compressed disk images are not supported.Besides 400K or 800K, the replacement disk driver of MinivMac will also work with disk images of any other size lessthan 2G. The utility CnvtDC42converts Disk Copy 4.2 format images to a newimage without the tags and checksums and header,that Mini vMac can write to. These images are mounted read only. The informationon a floppy disk can be transferred to a disk image file.The preferred disk image format for Mini vMac is a filecontaining just the image data, with no header, trailer,or resource fork (and therefore without checksumsor tag data).Mini vMac will accept disk images in formats withtrailing information and no header, except thatit will pass an incorrect disk size to the emulated computer,which affects programs such as Disk First Aid.Mini vMac also supports disk images in вЂњDisk Copy 4.2вЂќ format,which has an 84 byte header, and usually contains checksumsand tag data. In addition, an external floppy drive can be attached.Mini vMac does not emulate the floppy drive hardware butinstead patches the ROM with a replacement disk driver,which can mount up to 6 вЂњdisk imageвЂќ files. SeeвЂњ AutoQuitвЂќ.The Macintosh Plus has one internal floppy disk drive, thatcan use 3.5 inch 800K double sided disks or 400K single sideddisks.

The older вЂњMacintoshFiling SystemвЂќ (MFS) will also work, but this mostly is usefulonly for communicating with the emulation of the Macintosh128K. The Macintosh Plus doesnвЂ™tunderstand the newer вЂњHFS extendedвЂќ. Mini vMac defines its own icon for thesedisks (with a вЂvвЂ™), which can be seen in the Finder on theemulated computer.Bootable disk images should use the вЂњHierarchal Filing SystemвЂќ(HFS, now called HFS standard). This is not too authentic, but itis very useful.

Also in the Macintosh or Windowsversions, choosing the вЂњOpen Disk Image.вЂќ command from theвЂњFileвЂќ menu,or the вЂOвЂ™ command from the Control Mode,will bring up the standard dialog to select a disk image file. In the Macintoshor Windows versions, the icon of the disk image file can bedragged on to the Mini vMac application icon (If Mini vMac isalready running, in the Macintosh version the disk image willbe opened in the existing process, while in theWindows version a new instance ofMini vMac will be launched). This can be changed with theвЂњ -ndp 0вЂќcompile time option.Mini vMac can boot with any system version that works on areal Macintosh Plus, that is, up to вЂњ7.5.5вЂќ.There are many ways to вЂњmountвЂќ a disk image in Mini vMac.(That is, to insert an emulated disk into an emulated floppydrive.) The icon of the disk image file can be dragged on tothe Mini vMac window (Then, if the Mini vMac window isnвЂ™t infront, it will be automatically activated). However, to help prevent accidentally corrupting other files,Mini vMac will by default refuse to mount disk images that arenot HFS or MFS.
