I would like to know about sponsor versions. I would like to know if is possible I sponsor one. reply at [... email address ...] .

It certainly should be possible. The bottom of the Variations Service Directions page gives directions for sponsoring a variation.

Let me know if anything isn’t clear, or if you have any suggestions for improving the Variation Service.

I’m thinking I should split the directions for sponsoring to a separate page, and link to it from places like the latest variations page.

New version Mini vMac 3.5.7 wont run on PPC G3 systems.

Console crash log: "incompatible cpu-subtype"

Thanks for the report. I have verified this issue on PowerPC G3. It turns out my GCC compiler version defaults to requiring G4 or later. I think I have a fix (changing the command line arguments generated by the Mini vMac build system).

The fix should be included in the next version, probably Mini vMac 3.6, unless some other serious problem turns up in 3.5. (Since nobody reported this in the 4 month beta period, I guess it isn’t too high priority.)

update - Mini vMac 3.5.8 should fix this.

Hi Paul,

Mini vMac stopped with code 0301 when I tried to open the background script of a card (the last card, where the user level is set) of Hypercard 2.2's Home stack. System 7.1.2. The host is running Windows 10 (32) on an Atom processor.

As regards the "sound" error I got the other day I haven't yet been able to reproduce it. I'll stay on the case.


Kind regards, Karl

Do you know about Classic Menu? I've used it for years and love it. However, it is 32-bit. Apple will soon kill all those apps. So, how can I get Classic Menu to be 64-bit? Is there someone to hire to do this.

Currently, Classic Menu is not being developed.But you can get the source code from http://www.sigsoftware.com/classicmenu/. Can you suggest anything that might help me keep this app alive?

Jorge Santini [... phone number ...]

I’d think the first step, if you haven’t already, is to ask the original developer. There is a contact form on that site.

I’m not the right person to ask. Classic Menu is pretty much the opposite of Mini vMac, which tries to look like a simple, standard, well behaved application from the the point of view of the operating system. I’m not an expert on OS X programming, and don’t want to be. Most of the complexity of Mini vMac is in platform independent code which is of no concern of the operating system.

Classic Menu seems to be mostly about modifying the behavior of the operating system. This sort of thing tends to be very brittle as the operating changes. Updating it to modern MacOS would likely require a complete rewrite (to start with, moving from the Carbon API to the Cocoa API), if it is possible at all. The general trend has been to restrict modifications of the operating system.

Probably the simplest and cheapest way to continue using it is to run it in a virtual machine. The Classic Menu page says it has problems with OS X 10.7. VMware Fusion, for example, supports running OS X 10.6 server.

Hi Paul,

today I've had a crash on a Mac II mini vMac with mini vMac Code 0F19. System 7.1.2, I was working in Hypercard 2.2. Hope this info helps,

Kind regards,

Kar l

Code 0F19 indicates Mini vMac reached a part of the emulation of the Apple Sound Chip (ASC) that hasn’t been implemented yet. The problem of ASC emulation is a bit different than for FPU emulation. The FPU is fairly well documented, but extremely complicated. The ASC is much less complicated but not documented at all. So to emulate the ASC, one can observe how code is trying to access it, and guess what it is trying to accomplish. There is no way to implement a feature of the ASC without finding some code that uses it.

So, if you can give me a reproducable path that gets the Code 0F19, there is some chance I can fix it in a reasonable amount of time.

Support for two versions of the ROM from the “Twiggy” Macintosh prototype is new to Mini vMac 3.5 Beta. This is not currently supported by the Variations Service, you need to compile your own version. Be aware that normal Macintosh disks will not work with it, you need images of System Software made for this particular hardware.

The various Parameters stored in PRAM on a real Mac, such as caret blink speed, sound volume etc., aren't stored by Mini vMac, instead the Emulation uses the values defined during compile time (if I understand right).

Now that Mac II emulation is in stable beta, could you perhaps add a parameter for the colour of selected (highlighted) text? This can be set in at least System 7's "Color" Control Panel, but the setting currently doesn't survive a shutdown and restart of Mini vMac. Thanks!

First, thank you for your work on Mini vMac; it is a phenomenal program! My question, though is how to correct my Apple keyboard's Option and Command keys being recognized as switched?

That is, in Mini vMac (and only in Mini vMac; the keyboard works correctly in macOS/OS X), when I press Option MvM recognizes a Command key, & vice-versa.

I know you have a compile-time option to switch the Command & Control keys, but is there any way to have MvM swap the Command & Option keys? (Or am I missing some other cause for my problem?) Thank you!

~Travis Clark

Thank you for the bug report. That is strange, it hasn't been reported before. What kind of computer, and operating system, and keyboard are you using? And what version of Mini vMac?

If a keyboard for Windows is attached to a Macintosh, the position of the option and command keys will be swapped. But that applies to all software, not just Mini vMac. I was thinking about providing a option/command key swap for this situation.

How do i install colors in system 6.0?

For one thing, to see colors you will need the Macintosh II emulation. When installing the System, you may want to include “32-Bit QuickDraw”, so it can work with thousands or millions of colors. This used to be required for Mini vMac to work in color at all, but this seems to have been fixed by Mini vMac 3.4.

Follow-up to: Can you tell for sure whether it says “Abnormal Situation” at the top? It is very hard to imagine how this message can be shown more than once per run of Mini vMac...

-> I can't see the words "Abnormal Situation" in the window. I tried to provoke the behaviour by hitting keys, moving the mouse (i.e. finger on trackpad), clicking etc. It seems that the tablet (or, rather, ist keyboard) "sees" a CTRL key press when I press the trackpad in a certain way.

The window does not appear when I am very gentle and careful with the trackpad.

My Interpretation is that the build quality of the tablet's keyboard is rather poor and that Mini vMac is behaving as it should - it's the tablet's problem, not Mini vMac's. I've not come across this behaviour on other machines on which I've tried the same variations. Thus, false alarm. Apologies! Kind regards, Karl

That’s good news.

My guess of what may going on is that the trackpad can detect multiple finger gestures, but doesn’t have a direct way to report them to the computer, and instead tries to fake it. So perhaps a two finger tap is simulated as holding down the control key while clicking the mouse button.

Paul - apologies, I am using 8480 and 8481, not 8440 and 8441.

This is happening on a rather cheap Windows 10 tablet with an Atom processor. The number is very briefly shown in the window that usually pops up when I hit the control key (to set speed, full screen etc). The window shows up for maybe a fifth of a second and then closes again without me pressing any key. I haven't seen this on any past variation that I've tried on other computers (Macs and PCs).

My impression is that it's happening when I move the mouse cursor using a trackpad on the keyboard attached to the tablet.

I'll try those same variations on a "real" pc, i.e. a normal Windows 10 laptop, as soon as I can and will report back.

Regards, Karl

Can you tell for sure whether it says “Abnormal Situation” at the top? It is very hard to imagine how this message can be shown more than once per run of Mini vMac. However, Mini vMac can also display other error messages in a similar style. In which case the top line would say something else. Another possibility is that the error is actually being only displayed once, but somehow getting suppressed temporarily. But in that case the keyboard shouldn't work.

By the way, what specific kind of Windows 10 tablet are you using? Perhaps I should buy one for testing, as I don’t currently have anything like that.

Hello Paul,

I'm using variations 8440 and 8441. I am shown many, many "Abnormal situations" very briefly during normal Operation - in fact so briefly that I can't see the number (and thus won't be able to report it).

Thus a suggestion: Have the software collect the abnormal situation codes and display them on demand from the control mode (perhaps via a new entry).

Thanks for your great work, kind regards, Karl

Thanks for the bug report. This is very strange. Mini vMac Abnormal Situations reports should not behave this way. The report should stay up until the ‘c’ key is pressed. And after the first report no more should be displayed until the program is quit.

Are you quite sure this is a Mini vMac Abnormal Situation report, which is displayed in a similar style to the Mini vMac Control Mode, and not some sort of error message from the emulated Macintosh?

Does pressing the ‘c’ key stop the reports? What specifically are you doing when the reports appear, or does it happen in multiple situations? (Including what System Software version, and what applications?)

By the way, varations 8440 and 8441 are of Mini vMac 3.4.1, where Abnormal Situation reports do not report a number. Reporting a hexadecimal number was added in Mini vMac 3.5.6.

There is a compile time debug option for outputting a log file, including all abnormal situation reports. This can potentially quickly generate gigabytes of output, and completely fill a disk. For less advanced users, this could be an unpleasant situation. So this is not a supported option for the variation service.

Hi Paul,

I am trying to use FDisasm to disassemble the final version of the NewWorld ROM (the "CDG5" project at the MacOS9Lives forum if you're interested). Although I am making progress, I need to patch FindCode to treat F-line opcodes as valid code.

But all my compiles of FindCode (using Symantec C on MPW 3.6d7/Mac OS 9.2.2, and MPW C on MPW 3.1/System 6.0.8) produce an app that quits immediately on launch. It seems to be a clean quit, not a crash. I am able to compile FDisasm without a problem, however.

Any thoughts?

Best wishes, and my congratulations for your great work,


This sort of problem would normally be tracked down with a debugger. If that is not convenient, another approach is to insert a single SysBeep call somewhere in the startup code and see if you hear the beep. By moving the SysBeep call around, you can figure out exactly where the failure aborted the startup.

FDisasm is believed to be pretty accurate, since it can disassemble a number of ROM images well enough to be reassembled back to the original image. FindCode is not so easy to test. Worse, it hasn't been updated as fixes were added to FDisasm. Probably it would be simplest to throw out most of the instruction decoding in FindCode and derive it again from the FDisasm code.

This sounds similar to a previous message. The previous reply:

If so, moving an application into another folder from where you first unzipped it is supposed to be one way to disable this.”

“Otherwise, as documented in the ROM section in the Emulated Hardware Reference, there are two other place Mini vMac for OS X will look for the ROM image: “/Users/[your_UserName]/Library/Preferences/Gryphel/mnvm_rom/” and “[Application Bundle]/Contents/mnvm_dat/”.”

Is there a set folder that mini vMac winds up in? Also, as I'm using a Windows emulator (Basilisk II) to carry out the Mac functions, I'm finding the Stuffit-expanded system startup files are, when transferred from Mac to Windows, winding up still with a .bin extension. I'm going to try manually changing those to .sea but wasn't sure if there wasn't something else going on.

Hey Paul,

I've got two bits of feedback for you

1. Using my compilation of 3.4.1, I can boot every classic version of Mac OS except 2.0.1b (System 4.1, Finder 5.5) and System 5.1 (System 4.3, Finder 6.0). These two require me to use a non-color hardware for some reason, even though both should theoretically work with a Mac II (where some of the earlier Systems that DO work, obviously should not). Any idea what might be going on here?

2. I've been having difficulties building minivmac-3.5.6-imch under macOS Sierra in XCode 8.3.2. I'm getting the fatal error "source is configured for 32 bit compiler" but I can't figure out where this is coming from. Is there some new undocumented config flag for 64-bit in the config system? Have I somehow forgotten an -ev value that's needed?

Thanks for your tireless work and feedback!

Sent: Mon Jun 5 06:18:55 2017

Finally figured out how to get rid of the fatal error: set the architecture to 32-bit only. That seems odd though; my older builds handled 64-bit just fine, and the error check is the same in old and new builds. Did something change in the target build script?

Thanks for the report on the Macintosh II emulation issue. It seems similar to this previous message.

Regarding the second issue, for anyone else, to compile the Mini vMac 3.5.x using recent XCode, you can use options to the Mini vMac build system like “-t mc64 -ev 8210”.

It will boot up just fine but when using More About This Mac (which comes with OptiMem RamCharger 8) it will say "zero K" for several things including the built in memory (I am using system 7.5.5) . Using the same build options with Bloodshed Dev-c++ works as expected but that doesn't allow building 64 bit versions. More About This Mac can be found here : http://www.jumpdev.com/

Here is what I am using that is not working like it should (it doesn't matter if I use wx86 or wx64 the result is the same). Yet do the same exact thing with -e dvc it works fine.

Thanks for the bug report. I have verifed this happens with just the options “-t wx86 -e lcc -m II”. And I have also found this happens in Mini vMac 3.4.1 too. I notice that Speedometer doesn’t work either.

I’d suspect a bug in lcc, but I don’t know for sure that Mini vMac is not doing something that isn’t defined by the C language.

If you just want a working version, you can you request one from the Variations Service. It would likely also be several times faster, since Mini vMac 3.5 is optimized for a particular version of the gcc compiler, and not lcc.

how do you unzip file once you have downloaded on a mac

A double click on the file icon should work.

I’m not sure what sort of file you are talking about. Perhaps you mean a Mini vMac application archive, whose name ends in “.bin.tgz”. This a Gnu Zip compressed TAR archive. OS X has the built in ability to decompress it. Double clicking on the icon is one way. You can also select the icon and chose the “Open” command from the “File” menu. Or you can right click on the icon and choose Open. And there are a number of other ways.

Or you might mean a zipped hfs disk image from my collection of Software for Macintosh Plus, or one of the Mini vMac Extras. OS X has the ability to decompress these too, using the same ways described above.

G'day Paul,

I have been using Mini vMac for years. Simply fabulous.

I recently installed it on my Android phone (Android 5.1) and it boots up with the floppy disk icon with flashing question mark.

This is obviously looking for the boot disk image but unfortunately there is no menu to allow me to either drag the image or look for it. This is similar to the Linux version but at least here, the Mini vMac doesn't fill the whole screen so I can just drag the image into it and hey Presto!

I am pretty conversant with the emulator, but I cannot for the life of me figure out how to access the boot image.

Tell me I am stupid because I am fairly certain I am missing something very obvious.

In the meantime, keep up the good work. Are you planning to to ever do a colour version that runs say OS 8 or 9?

G'day again Paul,

Yep... I'm stupid.

I finally worked it out. On Samsung Galaxy there is no menu button but rather it is a long press on the left hand screen button.

This brings up the opportunity to insert the boot image.

Perhaps you might want to post this to FAQ so other idiots like me can figure it out.

Works like a charm. Thanks again Paul

I’m glad you figured it out.

I’m not involved in the Android port of Mini vMac, and don’t know much about, and in fact have never used it, which is why there is no documentation about it on this website. Perhaps in the future this may change.

The last version of system software that Mini vMac may eventually be able to run is 8.1, as mentioned in the FAQ (and the last version Mini vMac can currently run is 7.5.5).

The incomplete Mac II emulation of Mini vMac can do color, and works well enough to play many games. (It should not yet be relied upon for more serious uses.)

Thanx for great software!

I wish that you in future versions could include some easier way to exchange files between host computer (OSX) and Mini vMac - perhaps a folder that would look like a volume in Mini vMac.

Also, support for reading the host computers's CD-drive would be great!

Thank you for your donation.

I wouldn’t say never to a shared folder, but it would be complicated, and there are many other things with higher priority. Meanwhile, there is ImportFl, ExportFl, and MiniUnZp.

Using a CD-drive might work on some operating systems by mounting the device file as if it was a disk image file. Otherwise, you could make an image file from a CD and then mount the image in Mini vMac. Making an image file is a good idea anyway, for backup. A CD won’t last forever.

I tested your beta mini vmac 3.5.3 on Mac OS X 10.5.8 on Power PC. It Works for me.

Are you doing away Mac OS classic build ? I look they are no Mac OS classic build on this Beta page.

I hope to bring back classic 680x0 and PowerPC builds eventually. Both appear to be currently broken by compiler bugs. Perhaps sometime I’ll try harder to get the Retro68 compiler working, and then port changes to GCC version 4.7.4, which I use for all other targets. The 680x0 build turns out to have been broken in Mini vMac 3.4.1, and no one reported it until recently.

Hi. I downloaded "SSW_6.0.8-1.4MB_Disk1of2.sea.bin" and "SSW_6.0.8-1.4MB_Disk2of2.sea.bin", but I get the message "the document ... could not be opened because it is damaged or incomplete". Trying with Stuffit, I get a System Startup Image, but when I click on it, I get the message "legacy image should be converted". Is there something that I can do to continue? I use OS X (10.12.3) and a late 2013 iMac. My email is [... email address ...]. Thank you

Problem solved. [... email address ...]

THANK YOU It is great!


I’m not sure what the issue was, but I’m glad you solved it.

For anyone else, the Getting Started with Mini vMac page discusses ways to extract the System disk images and what to do next.

Hi Paul,

I noticed that all the Dynamix adventure games (Willy Beamish, Heart of China, Rise of the Dragon) cause the system to crash when launched when emulating a Mac II. It displays the bomb icon and states a system error has occurred, illegal instruction. Are you aware of this issue and is there any prospect of it being resolvable in future releases?


Thanks for the bug report. This was much easier to debug than I expected. It turns out that for the CMPI instruction Mini vMac is considering some addressing modes to be illegal when they are actually fine. This should be fixed in the next 3.5 beta.

Hi Paul,

Moving the rom file to "[Application Bundle]/Contents/mnvm_dat/" worked perfectly for the Mac Sierra issue I was having with the custom builds. I missed that self-contained write-up when looking through the site.



That’s good you have it working. I should get OS X 10.12 and look into the Path Randomization stuff. (But there may not be anything to do except document work arounds.)

[previous message]

Hi Paul,

My apologies for not including enough details in my original message.

I cannot get custom variations from the variations service to recognize the necessary ROM file. Checksums match although the message is "unable to locate ROM image" rather than corrupt or incorrect ROM.

OS: OS X 10.12.4 (Sierra)

Path: "/Applications/Classic Mac Emu"

My primary issue is with builds for the Mac II rom (e.g. builds 7976, 7977, 7978, 7980, 7981, 7982, 7983).

The md5 checksum for file "MacII.rom" located with the apps in "/Applications/Classic Mac Emu" is 66223be1497460f1e60885eeb35e03cc which matches one of the expected Mac II md5 checkums at http://www.gryphel.com/c/mac68k/

I also tried the MacII.rom file included in the CJ-Classics app, but it failed with same message even though it works with the 3.4.1 Intel build inside the app bundle and reports "Macintosh II" in "About This Macinstosh...".

This rom file has the md5 checksum 2a8a4c7f2a38e0ab0771f59a9a0f1ee4 which matches the Mac II FDHD/Mac IIx/Mac IIcx/Mac SE/30 checksum at http://www.gryphel.com/c/mac68k/

The rom is named "MacII.rom" rather than "MacIIx.rom" which confuses me. Based on earlier messages in the archive, I take it you built the CJ-Classics app (thank you again), so I must be missing something. I've searched your entire site to see if 3.5.x beta is set up different or what I might be doing wrong, but can't figure it out.

I previously had an issue with build 7984 and vMac.ROM but it works fine now and I can't recreate the issue. But build 7847 in the same folder with the same vMac.rom that works with the standard 3.4.1 build fails with "unable to locate ROM image" for "vMac.ROM" message.

Standard Mac drive format so it's not case sensitive, but renaming the files to .ROM do not resolve the issue.



Thanks for the further details.

I’m suspecting this has something to do with a new security “feature” in OS X 10.12: Path Randomization. The operating system can copy the application somewhere else before executing it. If so, moving an application into another folder from where you first unzipped it is supposed to be one way to disable this.

Otherwise, as documented in the ROM section in the Emulated Hardware Reference, there are two other place Mini vMac for OS X will look for the ROM image: “/Users/[your_UserName]/Library/Preferences/Gryphel/mnvm_rom/” and “[Application Bundle]/Contents/mnvm_dat/”.

I'm putting together a system using a raspberry pi, a 1024x768 lcd and a touch panel.

My intent is to run minivmac, full screen, magnified 2x.

Works great with a mouse, and the touch screen works if windowed.

What happens in the full screen is that the scaling of touch is off. A middle rectangle of 1x size is getting scaled corner to corner in the 2x screen.

Can you suggest where in the code would be a good place to fix this scaling?


Using a touch screen in Full Screen mode will probably work better with the “-emm 0” option.

Hi Paul,

Thank you for mini vMac. I've searched your site and apologize if I missed a easy answer but I cannot figure out where to store the associated ROM file for the custom 3.5.x builds. When stored in the same folder as app, the emulator complains it can't find the required file ("MacII.ROM" or "vMac.ROM" respectively). The filenames and md5 checksums are correct. What am I missing?



Thanks for the bug report. By custom builds, do you mean from the variation service (in which case, what is the variation number), or that you have compiled yourself (in which case, with which options, and what development enviroment, including version)? In either case, what is the host operating system and version? Are there any odd characters (anything besides a-z and 0-9) in the path (the names of all enclosing folders)? Does it make any difference if you move the application and ROM image somewhere else (like the root folder of the boot disk)?

After trying to compile in Visual c++ 2005, i keep getting this message.
