just leaving a post here to document that there is a code hidden in Kirby's Avalanche that can warp you straight to the "you win" screen.

To do this hold Right and L on controller 1 and Left and R on controller 2 either power on or reset the current game and you will warp straight to the credits.

This most definitely defeats the whole nature of actually speedrunning this game so I'd like clarification to be added in the rules that codes like this are not allowed.

I added it in the rules. Thank you for letting me know!
