[Famicom] FDS saving through UPS patch

I’m playing a Famicom Disk System game (Zelda). However, it (Nestopia UE through bleeding-edge RetroArch) doesn’t save progress.

What I would want it to do is to produce a UPS file which contains progress relative to the FDS-dump file.

Am I doing something wrong? Or is that just something waiting to be implemented or something?

It does save just fine on PC and it’s the same core on Wii. It was fixed recently so maybe it’s just you’re using an outdated core

Thanks! great news.

which means all that’s left now is microphone support!
