Can't really fina a good quality pic at 5am, but iQue games were distributed digitally, either via stations or, later on, your home PC. In general though, boxes for the iQue were vertical, like Japanese N64 boxes.
But honestly, there's really no way that Quest 64 thing is legit. For one, iQue is only in China and replaces the Nintendo branding (it was actually still going on during the early 3DS days, not sure about nowadays), no reason Mexico would have anything to do with that, as it was specifically made for the Chinese market.
Another thing that points against it, is quite literally the box itself. It says "Nintendo 64" instead of anything iQue branded (the Chinese "N64", so to say, was called the iQue Player in full). And by extension, there's no way the game would've also kept its name in this case, considering "Quest 64" wouldn't make any sense anymore, as it would not be a Nintendo 64 game at that point. Every other game also dropped the 64 from their title. Random fun fact, Star Fox 64 3D actually kept the "64" when released, it kinda slipped through the cracks. Neither the original nor Mario 64 DS had it in their title.
Well, and lastly, another thing that points against it being iQue related is the simple fact that Quest 64 (and its many names) is not a first party title. Only they were ever released for iQue systems.
I should mention that I'm talking about mainland China here. Other places like Hong Kong might've been more lax, but that's not a rabbit hole I wanna go down at 5am. In fact the whole early days of video game distribution in Asia is quite a fascinating mess, a mess which still has an impact to this day in those regions. Like, for example, South Korea was also very strict. But that's not for here and now.
In short, that box art is very likely fake or just a mock-up. And in the very slight chance it's real, it has absolutely nothing to do with the iQue.
