Fan modifications, translations, and total conversions
A Super Mario World ROM hack designed by a Japanese creator to torment his friend, featuring invisible blocks, pixel-perfect jumps, and enemy placements that require near-perfect execution throughout.
An officially licensed port of Super Mario Bros. developed by Hudson Soft for Japanese home computers, featuring new levels, new items, and scrolling replaced by screen-by-screen transitions due to hardware limitations.
A full NES Metroid total conversion telling the prequel story of Samus's rival Rogue, featuring an entirely new map, new enemies, new music, and new mechanics built within the NES Metroid engine.
A complete overhaul of A Link to the Past with an entirely new overworld, dungeons, story, and extreme difficulty, widely considered one of the most ambitious SNES ROM hacks ever made.
An unofficial bootleg translation of Pokémon Crystal into Vietnamese, produced by an unknown commercial pirate operation, featuring machine-translated and wildly garbled English text that became infamous for its absurdist dialogue.
A fan translation of the original Mother (NES) into English, completing the localisation that Nintendo of America had prepared in 1990 but never commercially released.
A randomiser mod for A Link to the Past that shuffles all item locations throughout Hyrule, creating an endlessly replayable item hunt that spawned one of retro gaming's most active competitive communities.
A ROM hack of the North American Final Fantasy II (SNES) that restores the Japanese script, reinstates content removed for the US release, adds a naming option for all characters, and corrects the significantly reduced difficulty of the localised version.
A selection of landmark community megawads for Doom II representing three decades of continuous community level design, from Erik Alm's combat-purity experiment to John Romero's own official return to the engine.
An unlicensed NES port of Street Fighter II: Champion Edition produced by a Taiwanese pirate developer, technically impossible on the hardware but shipped anyway, producing a grotesquely degraded but culturally fascinating bootleg.
A total conversion of Mega Man 4 that replaces every stage, boss, and weapon with original content, adding mechanics technically impossible on the NES through extraordinarily precise assembly programming.
A total conversion of Super Metroid featuring a completely rebuilt Zebes with an expanded map nearly twice the size of the original, redesigned physics, and new areas that extend the game's play time by several hours.
The most famous fan translation ever made — the first RPG ever fully translated by fans, produced by a handful of amateurs with no professional experience, and the project that inspired an entire generation of ROM hackers.
For an entire generation, this fan patch was the only way to play the sequel to Secret of Mana in English — a technical triumph that defeated the game's layered text compression nearly two decades before an official translation appeared.
The first Pokémon hack to completely reinvent the game — replacing Kanto with the entirely new region of Rijon, with original maps, a new plot, and even new elemental types, setting the template for every ambitious Pokémon hack that followed.
A hack that rebuilds Super Metroid as a retelling of the original Metroid, importing Zero Mission's physics into the SNES engine through extensive assembly modification.
Not a difficulty hack — a rebalance. It fixes Final Fantasy VI's central design problem, which is that its character customisation system lets every character become the same character.
Shuffles every chest, song, shop item and NPC gift in Ocarina of Time into a random location — and then guarantees, by logic, that the resulting game is still completable.
