These instructions work for MacOS High Sierra as the host OS, although with some tweaking they may run under Linux/Windows. ZX Spectrum emulators available for the Macintosh platform, including Mac OS X.Here is a short guide on how to build QEMU to run Mac OS 9 with working audio. In the Name field, enter the name for the disk image.The trd file stores floppy disk image formatted by ZX Spectrum TR-DOS.

At this point, we're talking about having a Mac Plus with hard drive, and imaginary proprietary software that runs on the old computer and the new. Clone QEMU forkWithout a hard drive, of course, the 512K Mac Plus can't juggle 800K.I have also enabled LibUSB, KVM, HyperVirtualization Framework, and the Cocoa UI. Welcome to your home for Apple Macintosh cloud.Start by cloning the fork of QEMU with experimental audio support: $ git clone -b screamer qemu-screamerThen configure the source to use MacOS CoreAudio. Img use our generated disk image for the hard drive-cdrom /Downloads/Mac OS 9.
Harddive Images Emulator Mac OS 9 With/qemu-screamer/qemu-img create -f qcow2 macos92.img 5GIf you have an ISO of a Mac OS 9 install disc (a Mac OS X classic install disc won't work), then you can use that in the next step. I made mine 5 GB in size, which is plenty for Mac OS 9.In our qemu-screamer directory, we will use qemu-img to create the disk image. Create HD for Mac OS 9We will need to have a hard drive image for our emulated system. /configure -target-list="ppc-softmmu" -audio-drv-list="coreaudio" -enable-libusb -enable-kvm -enable-hvf -enable-cocoaThis will create a binary in qemu-screamer/ppc-softmmu/qemu-system-ppc that we can use. -M mac99,via=pmu will define the Mac model and enable USB support May not actually need this. -L qemu-screamer/pc-bios sets the BIOS. /qemu-screamer/ppc-softmmu/qemu-system-ppc -L qemu-screamer/pc-bios -cpu "g4" -M mac99,via=pmu -m 512 -hda macos92.img -cdrom "~/Downloads/Mac OS 9.2.2 Universal Install.iso" -boot d -g 1024x768x32 Install Mac OS 9This won't install quite like Mac OS 9 did, but instead use Apple System Restore to restore an image onto the hard drive.Start up QEMU with the following options: $. One partition is good.After initializing the disk, run Apple System Restore with the Mac OS 9 lives disk image as the source and your disk as the destination. Go ahead and do that, using Mac OS HFS Extended as the file system. -g 1024x768x32 default to 1024x768 resolution and 32 bit colourOnce it starts up, you will be able to run Disk Initializer to format your hard drive image. -cdrom "~/Downloads/Mac OS 9.2.2 Universal Install.iso" use the ISO for the cdrom -hda macos92.img use our generated disk image for the hard drive Record loan payment in quicken for macIt will open a dialog letting you select your ISO. If something breaks your Mac OS 9 installation then you can restore the file.You can dynamically attach CDs/DVDs to the emulated system by going to the menu bar on your host system for the QEMU application and selecting the option to attach to the CD IDE drive. /qemu-screamer/ppc-softmmu/qemu-system-ppc -L qemu-screamer/pc-bios -cpu "g4" -M mac99,via=pmu -m 512 -hda macos92.img -boot c -g 1024x768x32It should boot up and you will have a running Mac OS 9 with audio! TipsWhen the emulator is shut down, just make a copy of the hard disk image to create a backup. Boot Mac OS 9Similar to the last command, except we start up from the disk we created. Once done, shut down the emulated system.
