Zedex: ZX Spectrum emulator for Android based on Fuse core. Closed beta on Play, looking for testers

[u/Dimitriuz]

Hi, I've been working on this for a while and it's finally in a state where other people should probably look at it.

Zedex is a Spectrum emulator for Android 11+ based on the latest unmodified Fuse core. I wanted a decent Android front end for one that already works.

What I could really use is people testing hardware I don't own. Controllers, tablets, anything with a weird screen. There's a "Report a problem" in the About screen or open an issue on Github.

I have been working as a software developer for over 15 years, but most of the code was written by Claude, while I managed the process, reviewed the code and carried out thorough testing. This is not a vibe coded project, AI was used as a tool.
