Is this game a fangame or a emulation

Hi everyone I am just asking if this game would be considered a fangame or a emulation of mario kart. thank you in advance.

This is a fangame. Many of the playable character aren’t in the original SMK/MK:SC character roster, and custom tracks are not available

This is protected so you can play safely

If you want to create a custom track, you can create it with Track Builder
