I honestly wonder what the state of emulation would be right now if we could manually exclude the T from the internet.
It would have been just fine. Troons didn't write NESticle, ZSNES, Snes9X, Kega Fusion, or VisualBoyAdvance.
The difference between SNES emulators everyone's been using for a quarter of a century and Byuu's work is that the classic emulators set out to make games playable on PC, whereas Byuu set out to make a perfectly accurate simulation of Super Nintendo Entertainment System hardware. One of his websites had a blog article where he goes into it in detail, but in essence, he talks about how ZSNES is, in a sense, sort of like its own platform. There are homebrew games and hacks designed to run on ZSNES that do not work in other emulators and on real Super Nintendos, so therefore, can you really call those Super Nintendo games?
My personal answer? Who gives a shit.
My thought-out answer? Adding support for those games really isn't all that much different from adding support for the countless cartridges out there, both official and unofficial, that use bespoke hardware, therefore needing bespoke mappers that take these into consideration. While everything officially licensed for the SNES did work on a real SNES, the one unlicensed game contemporary to its time, Super Noah's Ark 3D, did not work on its own. It had a passthrough cartridge slot on top that allowed a licensed cartridge to allow it to bypass copy protection. By Byuu's logic, that means it's not a true and honest SNES game, and yet, nobody would earnestly try to say it isn't. It just needs a particular modification it's designed around in order to launch on a real SNES.
Byuu put an unbelievable amount of work into something that's ultimately superfluous. It's now the 2020s, and all original Super Nintendo consoles worldwide are probably over the hill in terms of when their capacitors are gonna give way and start dying. After that, it won't matter at all what won't run on original hardware, because all that'll be left will be what hobbyists have repaired. Not to mention, I'm certain almost everyone now experiences their favorite SNES games by way of emulation. Is the experience of someone enjoying Chrono Trigger for the very first time any less valuable because they didn't play it on original hardware, with an original controller, on an original CRT? Of course not. As long as the game is there in its full glory, cycle accuracy or potential compatibility with other games you'd otherwise never even think about doesn't matter. Sure, it's nice that we can run crazy rare stuff like Exertainment Mountain Bike Rally, but it's not worth anyone dedicating their entire life to it. 90% of everything is crap. ZSNES could play all of SNES' best hits way way back in 2002, and everything afterwards is icing on the cake. But to dedicate your life to it, only to wind up going nuts and killing yourself? Man, that's a life wasted. There's so much more to life than to sit around obsessing over a video game machine that was only active for less than a decade.
But, I mean, that's troons for you. They're like a different species than you and I. Always the victim, always the revolutionary, always unstoppable at the most useless and hedonistic activities imaginable. They cannot create, but they sure can obsess over taking the concept of video game console emulation as far as they can possibly go, which means support for crazy obscure software and hardware nobody honestly cares about. Not that I'm complaining, I enjoy reading about stupid stuff like Rockman X's original cartridges having broken copy protection, but it ain't worth all that ludicrous bullshit Byuu put himself through to obtain every cartridge ever made and dump them himself, so he has his own personally verified perfect copies of everything. Literally thousands upon thousands of cartridges. A mentally well man would never do such a thing.
