Top 23 Rust Emulator Projects

Many of the old games and movies still play back well with Ruffle installed (https://ruffle.rs/). Newgrounds embeds it by default for old interactive flash media that they couldn't convert directly to video.
It's not a perfect fit, but it works. The speed of Ruffle loading on a page is similar to that of Flash initializing, so you can arguably still make flash websites and animations to get the old look and feel if you stick to the Ruffle compatibility range. The half-to-one-second page freeze that was the norm now feels wrong, though, so maybe it's not the best idea to put Flash components everywhere like we used to do.
Runescape proved that Java could be a pretty decent system, but so many inexperienced/bad Java developers killed the ecosystem. The same is true on the backend, where Java still suffers from the reputation the Java 7 monolithic mega projects left behind.

- Project mention: A brand new 68k Mac emulator dropped last night | news.ycombinator.com | 2025-06-26
The original submission was to a post that explains why this is news, and not just a random project:
A brand new 68k Mac emulator quietly dropped last night!!
“Snow” can emulate the Mac 128k, 512k, Plus, SE, Classic, and II. It supports reading disks from bitstream and flux-floppy images, and offers full execution control and debugging features for the emulated CPU. Written using Rust, it doesn't do any ROM patching or system call interception, instead aiming for accurate hardware-level emulation.

I understand why links get re-written, but I think the context is relevant and can help the random reader who is unfamiliar with the project.
