From the author’s site:

It has been nearly 12 years since this project began. Many of this game’s elements are iterations and polishes on concepts found in prior projects. Mario Adventure 3 is more than a 12 year project, it’s a 20 year amalgamation of ideas waiting to see fruition. Many of the ideas seen in Mario Adventure 3 are improvements of prior game ideas:

Day and night system (Mario Adventure)

Weather effects (Mario Adventure)

Item shop (Mario Adventure and Luigi vs Mario)

Exploration heavy (Luigi’s Coin Quest)

Traversing and backtracking worlds across the entire game with no cutscenes (Luigi’s Coin Quest)

Hidden collectibles to gain access to blocked areas (Luigi vs Mario)

And so much more!

Overall, this is an ambitious projects that has involved:

Completely custom level format

A tile collision system built from the ground up

Object handling system rewritten from scratch

Every enemy rewritten from the ground up

4 brand new power-ups and expansions of 4 returning power-ups

New graphics effects including weather, new debris types, and displaying more colors than the NES can normally handle

And yes, this runs on real NES hardware!
