ER Mario 0.3.9 (early release)

Install: unzip, put your Super Mario 64 ROM (US version) in the folder, start with er-mario.me3 (needs me3). The first launch sets Mario up from your ROM; when the box says Setup complete, press any button and start the game again. Full steps in the README inside the zip.

Updating: move your ROM into the new ER-Mario folder. Copy the package folder too if you want to skip the one-time setup. Your Mario save is kept (it lives with your Elden Ring saves, not in the mod folder).

New in 0.3.9

• Mario is immune to poison, scarlet rot, bleed, frostbite, madness and deathblight.
• Punches and kicks do 20% more damage to bosses, dives 10% more.
• Fixed small hitches when playing in a language other than English.
