I hear you. I don’t know about the rest of the apps, but Voyager has a fairly robust set of filter options. I regularly block things for non-dramatic reasons (like I just have zero interest in a specific subject that gets a lot of posts).

I’m not sure about using Lemmy through a web browser and what options that affords.

We do have a very incomplete X68000 core, IIRC. It’s enough to play some games at least. I’ve played Castlevania on it. My understanding is that there isn’t much available documentation for the X68000, and what is available is in Japanese. Definitely a major challenge for recreating it in FPGA form.
