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
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.
