“DSi enhanced” means that the game uses the additional functionalities first introduced in the DSi to enhance parts of the game. This is not to be confused with DSiWare games, which are games that can only be played on DSi (and 3DS) hardware exclusively. These new features include an additional minigame called “Part Delivery” that uses the camera to control the direction of a ball, and the extra processing power being used to speed up certain parts of the game. If you are playing the original cartridge on a DSi or any of the 3DS family of systems, then you have this feature enabled.

It should be pretty apparent that having the DSi enhanced version of the game is the fastest version to run on. So if you’re running the game on a DS emulator, you will most likely be at a disadvantage since there are currently no DS emulators out there that support these DSi enhancements. The Twilight Menu mod for 3DS would actually be faster than both an original cartridge and an emulator because of there being no lag, but because of those very reasons it has been banned from speedruns of the game.

The new minigame that comes with this DSi enhancement can also be very inconsistent and annoying to control, so if you ever get this during a run, it’s recommended you exit out of it and go back to get a different minigame. However, if you’re using the current route of the game, you shouldn’t get this minigame at all since it only appears in World 4 which requires no repairs.
