I put an entire 1991 Macintosh Quadra with Mac OS 8.1 into an Electron app, together with a bunch of apps and games. It runs on Windows, macOS, and Linux... and JavaScript. Again: I'm sorry.

Go grab it here: https://github.com/felixrieseberg/macintosh.js
This is a toy, but you can transfer files in and out, mount disk images, and time-travel back to the 90ies.

The real work here was done by Christian Bauer, the master of classic Macintosh emulation, and @ur_friend_james, who compiled it with Emscripten 🙇‍♂️
If you're looking for an old game or app from years past, check out archive projects like https://www.macintoshrepository.org . I, for instance, just installed Encarta. Or the Japanese version of Mac OS 8.
Yeah, exactly! It’s the Macintosh Quadra 900, which is the hardware this thing is pretending to be.
