Square wave sounds are approximated, being forced to fit into the same 22255 samples per second as other sounds. Mini vMac estimates execution time using a table of average number of cycles for each of the 65536 primary opcodes. The ‘P’ command of the Mini vMac Control Mode gets the options from an existing variation, and includes this Branch setting. In Windows 7 and Vista, "C:\Users\[your_UserName]\AppData\Roaming\Gryphel\mnvm_rom\". Mini vMac doesn’t implement this feature. You will remain in the Control Mode until you release the ‘control’ key. While in Control Mode, visual feedback is displayed on top of the emulated screen.

So Mini vMac goes ahead and transmits the modern keys.
I don’t know of any program for which this emulation isn’t good enough, so there are no plans for an even lower level emulation of the mouse movement interrupts. The rollers are each connected to a disk with a series of small holes. Double mounting is not actually possible in Mac OS 9 or in Windows.

The emulated computer sees this as a disk with the lock tab set.

The emulated processor of Mini vMac can run at approximately that speed (1x), but a number of other settings are also available: 2x, 4x, 8x, 16x, 32x, and All out. The ‘I’ command of the Mini vMac Control Mode presses the Interrupt button of the emulated computer. In the X version mouse buttons 1, 2, and 3 are equivalent. The ROM (“Read Only Memory”) contains information needed for the Macintosh Plus to function, and the emulation of the Macintosh Plus also needs this information.

This might be changed in some future version. This small area of memory is preserved even when the power is off. This can be easier to read, since modern screens often have smaller pixels than in the original Mac Plus (about 1/74th inch).

No pull requests, please; to contribute to Mini vMac, contact Paul via the Gryphel web site. The "mnvm_rom" folder may be an alias to where ever you keep your ROM collection. For example, finding the application directory is not implemented in OpenBSD and Minix. See the “ Copies to the clipboard (of the real computer, not the emulated computer) a string containing the options describing this variation of Mini vMac. The Macintosh Plus has an external keyboard with its own processor. The method used to get the velocity (not just absolute location) of the mouse of the real computer may not work on all computers. The Macintosh Plus doesn’t understand the newer “HFS extended”. Work stopped on the emulator around 1999. Mount the source code disk image in Mini vMac. Mini vMac normally emulates a computer with 4M of RAM, but this can be changed to one of the other 3 values by recompiling. But you can make the operating system running within Mini vMac use a Dvorak layout if you want it. If you use a mouse or trackpad on iPad OS 13.4 or newer, it will be used automatically. It helps to preserve the battery on portable computers. It will pretend to have something more like a hard disk, though not exactly. The new "-svd 0" option is now implemented in classic Macintosh port. Another alternative is “ You can set the time of the emulated computer in Mini vMac, such as by using the control panel or the alarm clock desk accessory. The Magnify option is turned on automatically if your screen has high enough resolution (1024 pixels across or greater). Magnify Mode helps to alleviate this problem. You can always force Mini vMac to All Mini vMac disk access is currently synchronous, so, for example, mouse movement stops, and sound can be interrupted. Mini vMac is an open source emulator of 68000 based Macintosh computers. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. Actually, the file is really named “vMac.ROM.lnk” internally, but what you see is “vMac.ROM”.) Mini vMac has code that attempts to detect when this doesn’t work, and then switches to the absolute position mouse emulation. Mini vMac does not check if the ROM image file is too long (it should be 128K = 131072 bytes).

Mini vMac for iOS. But this emulation is not good enough for some programs (such as Crystal Quest, HeartQuest, Slime Invaders, Arkenoid, MacLanding, Apache Strike, Stepping Out, and Microsoft Flight Simulator), and for other programs (such as Dark Castle) it is preferable to constrain the mouse to the emulated screen, so you don’t deactivate Mini vMac by accident.

vMac for DOS in DOSBOX. This makes Mini vMac more efficient, since transfering images to the real screen tends to be expensive. Never mount an unlocked disk image simultaneously in two running copies of the emulator. And never mount a disk image in an emulator and at the same time mount it on the real computer. A disk image file may be locked. Mini vMac tries to correctly emulate the behavior of the SCSI port with no peripherals attached. The count is loaded from the RTC into low memory after the computer is turned on, and most of the time this copy is used and updated (by incrementing it every second) without referring to the RTC.
