Random: Super Mario 64 on NSO is home to strange typos

The Nintendo Switch Online + Expansion Pack’s N64 library is home to some strange little bugs that made us wary as we played through some classic games on the cartridge. Last week, we noticed one Weird speed issue in the recently added section Banjo-Tooieand now we have another one, this time from Super Mario 64.

As pointed out on Twitter by the source of all Mario obscurity, @MarioBrothBlogThe European expansion pack has a bug that results in some strange misspellings of selected level names.

According to Mario Broth, both ‘Cool, Cool Mountain’ and ‘Big Boo’s Haunt’ are error-prone, with the letters ‘O’ and ‘U’ being swapped if you switch between levels enough. That means, with a few level swaps, your pause screen might be greeted with ‘Great, hoe Mountain’ ‘Cool, cool Mountain,’ or ‘Big Boo’s haont‘. Odd.

What’s more strange is that no one seems to know what caused the error in the first place. Sure, it’s unlikely to be a game-changer, and we can’t see Nintendo rushing to patch it in a hurry, but it’s another oddity of the NSO N64 library.

Now, just wait for the speedrunning community to find a way to use this typo to shave milliseconds off a complete run…
