Super Mario Bros 3 as Dinosaur Land

Super Mario Bros 3 as Dinosaur Land is a Super Nintendo ROM hack that recreates Super Mario Bros. 3 stages inside the Super Mario World engine. Fento34 created the hack. The current SMW Central archive classifies it as a Standard hack with 120 exits. Recent gameplay coverage also documents version 3.4 and confirms the project’s main idea: SMB3 stages receive small changes so they work within the Super Mario World style, with secret exits, hidden Switch Palaces and additional secret content.

🏰 SMB3 Stages Meet Dinosaur Land

The title refers to the visual and technical foundation of Super Mario World.

Instead of using the separate world-map structure from Super Mario Bros. 3, this hack uses the Dinosaur Land-style framework associated with Super Mario World. That includes an interconnected overworld and the possibility of opening additional routes through secret exits.

This is an important difference between the two games. Super Mario World uses a large interconnected map with paths that can change as you progress, while Super Mario Bros. 3 organizes its adventure around individual world maps.

🕹️ Familiar Levels With Different Rules

You still rely on the core Super Mario World movement system.

That means you can:

• Run and jump through side-scrolling stages.
• Stomp enemies.
• Use power-ups.
• Spin-jump.
• Carry objects.
• Search for hidden routes.
• Use Yoshi where the hack provides him.
• Explore alternate exits.

🔑 Secret Exits Change How You Explore

Secret exits are one of the strongest Super Mario World influences in this hack.

A normal route may take you toward the expected goal. A hidden route can lead somewhere else on the overworld.

You therefore have two different ways to approach many stages:

Normal completion: Find the standard goal and continue along the main route.

Exploration: Search for hidden exits that open additional paths.

The current gameplay coverage specifically confirms secret exits as part of the project.

🟨 Hidden Switch Palaces

The hack also uses hidden Switch Palaces.

This is another clear reference to Super Mario World. These locations provide an extra exploration target beyond the main stages.

If you want to see everything available on the map, checking unusual routes is important. The Switch Palaces are part of the game's documented secret content rather than an assumption based on the original SMW mechanics.

🌟 There Is a Secret World Too

The hack contains more than SMB3 material.

Recent gameplay descriptions confirm a secret world with well-known levels from another game. The source intentionally does not reveal the identity of that game.

🌍 World 1 Starts With Grass Land

Fento34's own YouTube archive contains a 100% playthrough specifically titled World 1: Grass Land. The video describes the project as a Super Mario World hack based on Super Mario Bros. 3.

The use of SMB3 world names helps retain the identity of the NES game while the SNES engine handles the actual gameplay.
