I don’t think Nintendo developed it at all if it’s real https://t.co/GBNtBtgWHjThere have been some doubts over the origin of the emulator service. Developer ModernVintageGamer noted that there was a reference to EZFlash cartridges. As per MVG, if that turns out to be true, the chances of Nintendo developing the actual service seem unlikely.According to another data miner, the emulation service for Nintendo Switch is being developed by NERD in collaboration with Panasonic Vietnam.It remains to be seen if and when the leaks will turn out to be true. Nintendo hasn't made any confirmation, so players should take the information with a grain of salt. If the emulation service gets added to Nintendo Switch Online, it will be the fifth one to be added after the four existing ones.
