## Platforming changes the Lands Between

ER Mario puts Super Mario 64’s movement into Elden Ring: triple jumps, long jumps, wall kicks and ground pounds become ways to cross its terrain and engage enemies. Punches and kicks deal damage, staggered bosses can be swung by the tail and smaller enemies can be thrown. Mario’s eight-part health meter, coins and Lakitu camera reinforce that this is a different set of rules inside Elden Ring’s world.

It also changes the role of progression. Damage is based on a fixed share of enemy health, and Vigor does not enlarge Mario’s health meter. Strength, Dexterity, weapons, stamina, FP and equip load do not drive the normal Elden Ring build system here. The appeal is experimenting with movement and encounters, not optimizing an ordinary Tarnished build.

## Use the mod’s separate offline save

You need Elden Ring on Steam, me3 and your own US Super Mario 64 ROM. Extract the release to a writable folder, add the ROM and start er-mario.me3. The first launch extracts the needed Mario data; when setup finishes, close and relaunch as instructed. Start a new character because the mod uses its own save.

me3 launches offline with anti-cheat disabled, and the creator explicitly says to keep this mod offline. Xbox controllers, a PS5 controller through Steam and keyboard/mouse have been tested. Other pads use Steam Input to present the expected Xbox-style input.

## Switch cameras when the experiment gets awkward

F9 switches between Lakitu’s camera and Elden Ring’s camera. You can make the latter the startup choice in er\_mario.ini. If you become stuck, holding F1 for three seconds kills Mario and returns you to the last grace.

Elevator clipping can still occur, some thrown bosses produce unstable ragdolls and Mario’s shadow may flicker. Cutscenes can show a distorted Mario with the Tarnished’s head. Those rough edges are part of the current work-in-progress mod, so keep the separate save and expect occasional resets.
