METROID: Fused Facility is a simple hack of Metroid 1 on the NES, featuring a brand new adventure on Planet B-515, with the simple objective to destroy the growing X Parasites population on the planet. It features a completely brand-new map, new level design, new graphics, and even ports of Metroid Fusion music, courtesy of Amilgi. Much like the earlier Metroid Blue, you can also combine the Ice and Wave beam here and always respawn with full health. The paths are varied, and you have multiple ways to get through the base.

A hack of the original Metroid to make it feel like the 4th game on the GBA: Metroid Fusion. Kraid has been changed to Arachnus, Ridley has been changed to the SA-X, and the layout is inspired by Fusion’s map. Samus uses her Fusion Suit colors as well. All 6 sectors could not be exactly recreated, but the flow of the game should be there

Metroid Blue is a simple yet enjoyable vanilla hack of the original game, featuring a fully-redesigned map, new rooms, new palettes and improvements over the vanilla game.

Afflicted with perpetual nightmares, Junko is determined to defeat the manifestation of her dreams - the serpent trickster Asmodeus.

Metroid Confrontation 2: Return to SR388 is a NES Metroid hack, based on Gameboy’s Metroid 2 and a little bit inspired by AM2R. Made using the Editroid program (created by Snarfblam). A lot of things has ben modified: All graphics (backgrounds and sprites), all map, text and music; to look like Metroid 2. Unarmored samus sprites were based on rogue dawn hack.

This pack replaces graphics, sound effects, and music for the original NES game, Metroid. It is a hack that builds upon many prior hacks and it uses Metroid mOTHER as a base. It should be used with the Mesen 2 emulator.

Rogue Dawn is an unofficial prequel to the original Metroid game released in 1986. 30 years later we bring you the events that unfolded before Samus’s famous “Zero” mission on planet Zebes. The original Metroid manual tells us about a deep-space research spaceship that was attacked. Pirates seized a capsule said to contain a newly discovered life form in a state of suspended animation. Rogue Dawn surrounds these events that led up to the theft of the capsule which ultimately placed the Metroid’s under the control of Ridley and the Mother Brain. The mission to acquire the capsule is placed in the hands of one of Ridley’s best kept secrets. A rogue human agent trained and manipulated by Ridley from a young age. Taken as a child from a Federation colony obliterated by Ridley’s faction she was initially just another test subject slated to undergo horrific experiments. Ridley decided to instead manipulate and mold her into a weapon, his first human servant and dark agent. Primed yet untested she is sent out on her “zero” mission to retrieve a newly discovered biological specimen in the possession of a Federation research crew orbiting planet SR388 and prove her worth. Her name is Dawn Aran!

- All levels 100% redesign - New title screen graphics - New tile graphics - All levels (New level themes) - New creature graphics (A few classics will remain) - Animations created for all levels - Level design focused on fun factor, game play, attempt at minimizing frustration (There are some difficult areas). - Snarfblam’s save game and mini map hack applied

This hack is the combination of three individual hacks. It was created to be the ultimate NES remake of a classic game.

This hack replaces Metroid’s password system with a saving system, offering three save files. The file selection menu shows the player’s equipment, and as an added bonus, the player’s health is now saved (no need to grind for health every time you resume your game). The save system can be a handy addition for those who don’t like to use save-states, or those playing on a flash-cart. Included is a scrollable map when the game is paused and the ability to combine wave and ice beams. Version 0.3 fixes a bug that could prevent the game from booting correctly in some cases. The hack has been tested and confirmed to work on the PowerPak as well as a normal cart.

Classic NES Series: Metroid is a port of Metroid for the Game Boy Advance.

The full story of Samus Aran's first mission finally unfolds... The first Metroid game just scratched the surface of the cataclysmic events on planet Zebes, and at long last the rest of the tale has come to light. Experience the first of Samus's legendary adventures through all-new cut-scenes and action sequences as the bounty hunter races through the deeps toward her showdown with the leader of the Space Pirates. But will the end of Mother Brain really mean the end of the story...? Completion of the game unlocks an emulated version of the original Metroid game. Zero Mission also allow players to unlock the Metroid Fusion picture gallery by linking between Zero Mission and Fusion cartridges via the Game Boy Advance Game Link Cable.

This is one of the earliest hacks for the original Metroid. Screens, enemy and item placement, palettes, text, and more are all changed. The primary goal was to make the game more playable - the discerning player will note the careful placement of platforms and enemies to make jumps easier. However, beating the game will not be a cinch. Items are much more difficult to get, corridors are contorted into winding mazes, and many of the energy tanks have been completely eliminated.
