Hollow Mario

IMPORTANT: You must downgrade your Hollow Knight installation to version 1.5.78.11833 to play this mashup! (Downgrade guide in the Discord Thread!)

Welcome to my obsessively crafted mashup between Hollow Knight and Super Mario 64!

First up, a huge warning: This mashup is DIFFICULT, but I do believe it's fairly balanced if you're an experienced player of both games! I spent a LOT of time balancing it and am open to feedback and discussions on the Melty Discord server! (I am YoukaiMisha on there.)

(Debug keybinds at the bottom)

You start without the Long Jump or Wall Jump, but when you get the equivalent Hollow Knight unlocks, you'll regain your base skills and gain a few more for your arsenal that weren't in SM64.

You might also discover a few more intentional (but largely untested) skips if you pay attention~

Original art you'll encounter throughout your playthrough is drawn/edited/traced by me! (Not AI!) ((Don't expect too much, please!))

The game currently explicitly supports most charms, all upgrades, and most of the game otherwise. I didn't try to verify a full 112%, but I did verify up to 95% as Mario only before deciding this was ready for a public release! (White palace is a nightmare, and so is the final final boss...)

I would say most players who have beaten both games can get through the first ending with a bit of trial and error, but going for the true ending is a real challenge and requires quite a bit of abusing cheese strats and charm combos!

In general, Ground Pounds and Dives are going to be your best friends in the long run. Oh and you might get some use out of the Nail Master abilities!

Good luck! Have fun!

Mod Compatibility

This mashup will try to detect whether or not you're already using a modded installation of Hollow Knight.

If you're using the Community API, it won't inject itself via BepInEx and will instead run as a mod alongside your other mods. Of course, I can't guarantee this will be a bug-free experience, and I can't support issues caused by other mods, but it might be fun! (Archipelago Randomizer sounds fun!)

Important Debug Keys

M - Switches between the Knight and Mario.

F5 - Resets you to the start of the room you're currently in. (Useful if you manage to get stuck or clip out of bounds)

F7 - Enables visible hitboxes for Mario. F8 - Enables a simple Boss HP tracker at the bottom of the screen. F9 - SHOULD reset you to the last bench you rested at, but can be a bit buggy.

Requirements

Windows Steam version of Hollow Knight, downgraded to 1.5.78.11833

An unmodified legally obtained Super Mario 64 US ROM

No ROM or Hollow Knight game files are included in the download.

Known issues: Elevators can be.. problematic. The one in dirtmouth stag station and crystal peaks entrance have a mind of their own.
