Someone on GameFAQs claimed to have made an NES emulator on the Switch. Also for some odd and mysterious reason he was unable to use any of the main buttons and mapped the buttons to the shoulder buttons. It was shitposting but I like to see trolls flounder and try to keep up with their lies.

I'd post the topic but its deleted now.

It's GameFAQ, what do you expect?

it's actually real you just need to do the steps above to get The Nintendo Switch Homebrew Launcher it comes preloaded with a NES, SNES, 360 and XBone emulator.

But how realistic would a web based emulator be?

If I was at least half optimistic at least that would be a feasible possibility.

There is web based emulators. Just all of them I have seen require Flash.

There's this: https://fir.sh/projects/jsnes/

Also related: https://hulkholden.github.io/n64js/
I wonder how well that would run on the Switch, if at all.

And another thing that might be fun to test in the Switch browser:
https://win95.ajf.me/

Can't say I've seen any Flash based emulators actually, but I've seen plenty of Java based ones.

I would link the the Flash emulators I have seen, but the websites also host ROMs, so I can't.

Dude, I was like "wow what a stupid troll" when I first saw your comment but I've been like dying to get all those juicy Switch games without paying de monies and had to test and I was like WTF IT ACTUALLY WORKS

thanks so much dude how did you implement this globally across all units?

I snuck into the production line and loaded it into the joycons kernel

If you're Donkey Kong you just throw a banana-shaped usb into the nand flash unit

We still get silly stuff like that over in the 3ds threads. Like people think they are genius for thinking of possible exploits, when really it's a simple concept that has been tested and proven not vulnerable ages ago. And then a few months later someone else comes up with the same genius concept. It gets annoying.
Especially with the influx of the new people after 11.0-2 being hacked. Please PLEASE if you think you found something, try to actually think about it. If it was something you thought of fairly easily without any hacking experience, chances are the actual hackers thought about it months ago.

Has anyone looked into an SD card swap exploit? Typically the switch refuses to mount the SD card without a reboot, but if you use a cable like this one:
https://www.amazon.com/gp/product/B01F8C0LOO/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
The switch doesn't know when you've pulled the card. It acts pretty strange. When taking a screenshot, it tries to save it, then fails. But when I removed the card, formatted it, and reinserted it, it would try to save the screenshot and seemed to succeed, but nothing was written to the card. I even went so far as to copy all screenshots from internal memory to the SD card. No errors, but no files on the card either. I don't have any downloaded software saved on the card to see how it behaves then.

But if the switch doesn't know you've swapped cards, might it be possible to swap in a modified application after it's already booted? Even just a small change of code could theoretically be used to hijack the process right?

And if the switch does panic when the card is removed, then what about something like:
https://hackaday.com/2013/09/19/advanced-transcend-wifi-sd-hacking-custom-kernels-x-and-firefox/

The SD card, bewilderingly, mounts the flash memory as R/W to both the host OS (SwitchOS in this case) and the SD card's internal OS, which can be modded to allow SSH or even FTP access. It's bad form of course, but you can overwrite a file without the host OS even being aware of it.

That actually seems plausible.

I do apologize. You almost seem disappointed.
I imagine the usefulness of the idea depends a lot on when the SwitchOS verifies files are signed correctly. If its a continual thing, or a one time check. Also if the games are broken up into various files, or if its all just one large file.

I'm not dissociated, just the way I sometimes type.
