Alright so my lab is pretty much functionally complete; it does everything I was hoping it would and much more.
OK so now what :D Do you know of any projects that are self-hostable and serve no functional purpose whatsoever and exist just for fun? Could be silly projects, could be games. I’d like to add a “silly things” section to my publicly facing list of web services.
For instance, I was thinking of hosting a web version of nethack. Also I enjoyed hosting a node of hypermind for a little while just because it was so silly.


https://romm.app/ - Self hosted game ROM manager that lets you play retro games directly in the browser (using RetroArch cores compiled to WebAssembly).
https://retroassembly.com/ is a similar project.
There’s also https://gamevau.lt/ which is like a self-hosted version of Steam, for DRM-free games (like from GOG).
I like this but since it’s on my own domain i’m going to refrain from illegal stuff.
Would it be a publicly available page, or accessible only for you?
If it’s a public page, you could possibly host shareware games or with other licenses with a similar effect.
And there’s plenty of games you can legally buy as ROMs (e.g. homebrews on Itchio), games that include ROMs in their files (e.g. River City Girls 0 on Steam, most Neo Geo releases on PC platforms and pretty much any MS-DOS game rerelease), and if you’re from a region with laws not as draconian as the DMCA, there are games with ROMs embedded in their files and that can be extracted. So if it’s a private page, you could go for those too.
Password protect it and just let friends use it? Or have it just for yourself :D
