Nintendo has a long history of trying to kill emulation, even legit ones, and on PC, it’s very easy to emulate stuff including by legit means, so the joke is that Nintendo is saying to stop emulating, and PC gamers out of spite answer by emulating more (and if it’s “emulating more” by legitimate means or otherwise, it’s not clear).
If, by 100%, it includes 100% of the achievements/trophies, I can only remember Mary Skelter Nightmares¹, Odin Sphere Leifthrasir and Starbound as games I still enjoy after doing 100%.
¹og version; dunno if the updated version bundled with Mary Skelter 2 has trophies (didn’t stop me from finishing it on the Switch, though e.e")
The older Bomberman games, the Metal Slug games from the Neo Geo, Gunbird, King of Fighters 2002, Final Fantasy games like II (PSP is the most complete version), VI and Mystic Quest, コテ・DE・メクール (a PC-98 game), the first Shantae, modern homebrews like Tanglewood, Nyx - The Paradox Relic, Augury Red Code and Micro Mages, Mega Race, Kunio-Tachi no Banka (rebranded as River City Girls 0 in its recent release, and has an option to play with untouched dialogues), Wonder Boy in Monster World, Castlevania: Symphony of the Night, Phoenotopia (Adobe Flash version).
