Surprise! This was requested for years and it's finally happening! Why did it take so long? Well... I originally started this project in 2022, then took a solid break due to burnout, but better late than never, right?

About

This is a mod that allows you to play Mario from Super Mario 64 in Sonic Adventure DX. This isn't a character skin no, this mod has the exact same moveset and physics than the original 1996 game.

How you may ask? Just like the Sonic Generations version, this mod uses the awesome libsm64 (a popular library based on the sm64 decompilation) which made this entire thing possible in a first place, so big shoutout to anyone who worked on that.

Remarks

• The entire game is beatable as Mario, but you will sometimes need to be creative to beat a level, specially on the end game. Side Somersault, slide, jump kick and of course avoid rushing can be useful.
• Additionally, Mario can use the SA2 Light Dash so you can pass some parts of the game where it's needed.
• This mod also patches some objects and edit a few sets files to add some QOL for Mario, please make sure to load this below Dreamcast Conversion (or any mod that does set edit).
• Multiplayer mod sorta works, but Mario is only supported as Player One. If you really want to use it, make sure to load this mod below Multiplayer.
• Cutscenes aren't supported

Now and this is important: I tried my best to make the experience as best as possible, but you have to expect janks from time to time, keep in mind that Sonic Adventure was never made with SM64 Physics in mind, both games don't have great collisions either, which obviously isn't helping here.

Side note, but if you want a more faithful SM64 experience, I recommend grabbing the Animated Sprite Ring Mod and configure it so you can have SM64 coins.

Requirements

This mod does NOT include any assets from the game. You need a valid copy of a SM64 Rom (NTSC-U version). The mod expects the ROM to be in the mod folder and named 'baserom.us.z64'.

If it cannot find it, you will be asked to select the ROM file location when first booting the game.

SHA-1: 9BEF1128717F958171A4AFAC3ED78EE2BB4E86CE

Just like any SADX mod, you will need SAModManager, see Installation bellow.

Make sure to have either "Input Mod" or "Better Input SDL2" enabled in the Mod Manager as the library SDL2.dll is required to have SM64 Sound and Music to play.

Known issues

• It's possible to clip into collisions
• There are a few animations that don't interpolate / play properly
• Lantern Engine isn't affecting Mario (regular DX lighting works though)
• Expect jank from time to time
