I checked that game. It looks the same, but it’s not the same game I remember. I found my old 3DS, so I’ll look in there for some clues

The 3DS automatically keeps a log of every piece of software you've ever played/opened. To find it, open Activity Log (the icon resembles an upward trending graph) and select Software Library and look through that until you've found the racing game. Once you've got the name of the game, I'm sure the ROM has been preserved in a no-intro collection.
