Mario 64 in Hollow Knight

Press M to swap the Knight for Super Mario 64's real Mario, anywhere you can move freely. Press M again to get the Knight back.

• His real SM64 moveset in 2D: momentum running, single, double and triple jumps, backflips, side flips, long jumps, wall kicks, dives, slide kicks and ground pounds, on Hallownest's own floors and walls.
• Punches and kicks hurt enemies through the game's own nail hit, so they flash, recoil and die as usual. Damage scales with your nail.
• Your masks are Mario's health. The game's own damage, invincibility and death stay in charge; cutscenes, benches and doors still belong to the Knight.
• Single player.

You need: Hollow Knight (Steam) and your own Super Mario 64 (US) ROM. Melty finds it and prepares it when you press Play. Nothing from either game is included.
