Nintendo is introducing new features for N64 games on Switch Online on June 5, the launch day of Switch 2.
The new features include a rewind function that allows players to go back in the game to correct mistakes, but it will only be accessible on the Switch 2.
Another feature is the CRT filter, which adds a pixelated texture for a retro CRT TV look, exclusively available on the Switch 2.
For players not upgrading to Switch 2, the only update on June 5 is the ability to customize controller button functions for easier gameplay.
