Yes, many people have already written about emulating Mac OS 9, but only recently (2018) did experimental audio support come out for QEMU. I recalled that QEMU could emulate other architectures, surely someone has already tried to emulate Mac OS 9. My first instinct was to reach for VirtualBox, but that is a no go as I need to emulate a Motorola 68K or IBM PowerPC architecture. I was curious to see what applications were around back then - what about emulating Classic Mac OS to see? These magazines are freely available on the Internet Archive, including their cover discs. Building websites, graphic design, hacking the appearance of the UI, all these were explained in the pages of magazines. Growing up around that time, I remember reading a lot of MacAddict and MacWorld to learn what I could do with a Mac.
I recently got an urge to revisit old computer media from the late 90s and early 2000s.
