The Neo Geo Metal Slug games were extremely fun to play side by side with a friend. Just note Metal Slug 2 has lag problems due to the engine used, but it was later ported to MS3’s engine as Metal Slug X.
Also, most versions of the games on PC come with the ROMs, if you’d rather use your own emulator.
Another set of games we also enjoyed a lot were the River City Girls games. Just had to use health cheats on the SNES game repurposed because it was getting too hard for the time we had. "<.<
I’d try finding a community to where I’d like to post a given article, and look for its posts in the OG instance as well as in instances I have accounts on for other engines (the 3 major thread-oriented ones I know about are Lemmy, Mbin and PieFed). Other than that, of retarded/delayed results but still something I’d recommend, is to follow people in other instances (Mbin / microblogging / Peertube thing), and interact with everything the user finds so posts can propagate across instances, so at least in future searches, others, or even yourself, may find/refind posts more easily.
