There's a bit of a buzz around the emulator for Super Mario 64, as it supposedly contains references to various other Nintendo 64 games. This, of course, has got a lot of people excited about the idea of N64 titles potentially coming to the Switch Online service. The mention of Perfect Dark, in particular, even caught the attention of former Rare composer Grant Kirkhope.
Unfortunately, it might not mean anything. According to the data miners OatmealDome and LuigiBlood, this data is more likely to be "leftovers" from the Wii U's N64 Virtual Console emulator. Perfect Dark was also apparently listed back then but was never made available.
In other words, as exciting as it is to see games like Perfect Dark and Paper Mario referenced, it's best not to get your hopes up.
