I recently tried to search for certain Nintendo 64 ROMs because I wanted to try out an emulator. The first couple of results on Google all lead to horrible, ad-infested websites that claimed to offer a download but either kept on redirecting me to more ad-filled sites, or tried to get me to download some sort of "download helper", "media codec" or "PC cleaning software". Then there were the sites with dozens of fake "Download" buttons surrounding the real one. I'm still not sure whether any of them actually offer any ROM downloads (I found trustworthy sites on the second page of the results).
It's no wonder that many users struggle to keep their PCs free of adware, toolbars and similar junk, when it is shoveled into your face every step of the way.
They are really good, but they don't have everything (maybe due to copyright complaints, specially for Nintendo games which might have been re-released for new platforms.)
Ah yes, I didn't even think of that. But now that I've checked it out, it seems like they only have ROMs up too the SNES, and none for the Nintendo 64 ("only" videos, soundtracks and manuals)
You wanna search by obscure-to-outsiders collection names. “No intro”, “tosec”. That kind of thing. Pretty sure they have n64, in with the rest of a large multi-system collection.
The only thing that's changed about shady emulation sites in the last 20 years is that they no longer give you ill-conceived legal advice about ROM ownership being legal if you delete the ROM within 24 hours and/or are not affiliated with law enforcement.
