Super Mario 64: Decades Later v1.0

Hack by BroDute
Original Game by Nintendo

Considering this is an Editor/Binary Hack, you are best off to use Parallel Launcher with OGRE gfx Plugin to not run into problems while playing.

For more Credits, read a sign ingame inside the shed.

The Mystery Zip can be unlocked by getting all 150 stars.

This hacks aims to recreate vanilla SM64 levels from memory and remove stupid stars that I never liked in the OG.

That said, some levels will be similar to vanilla while others will feel like fully new levels, because of how bad the originals were e.g. Course 15.
If you desire new stuff, the endgame close to 150 stars is filled with new original stages just like SM64DS had new levels.
Good luck and have fun!
