The two original developers of ZSNES are finally back together! Introducing SUPER ZSNES! Re-written completely from scratch, this GPU-powered SNES emulator is here to bring you the following: some of what is familiar, some of what’s new, and then some of what goes beyond.
Key features:
- Far more accurate CPU and Audio cores than the original ZSNES
- GPU-powered PPU core to allow for hi-res Mode 7 and special per-game enhancement features
- Classic UI with falling snow, modernized with higher definition and improved UX
- Fast forward, rewind, save states, auto save history, save bookmarks, cheat codes, quick load, and more
- No Vibe Coding. Classic development style.
- Super Enhancement Engine, where the ZSNES developers are enhancing the games one at a time
Users didn’t flock to zsnes because it was the most accurate, they used it because it completely nailed the user interface for loading, saving, input, and configuration.
And because it was the first SNES emulator to play games full-speed on a 486.
Things changed after 0.800. My Pentium PC struggled after the following release. IIRC it replaced some assembler code with C code that was less efficient.
It looks like 0.700 is actually when they switched to C.

I believe it, though. SNES9X was coming into its own at about the same time period, and the inaccuracies were starting to catch up with ZSNES.
