From Hex Editors to Steam Workshop: How 90s ROM Hacking Built the Modding Scene
A World Before Mods Were Mainstream
Today modding feels inseparable from gaming. Entire communities thrive on places like Nexus Mods, and Steam Workshop makes adding fan content as simple as clicking a button. Bethesda titles like Skyrim or Fallout 4 are almost defined more by their mods than their base games. But long before modding became normalized and developer-supported, fans were already hacking away at their favorite titles. And they were doing it on 8-bit and 16-bit cartridges.
In the 1990s, before widespread broadband and before companies thought to ship games with modding tools, young players were cracking open NES and SNES ROMs with hex editors and tile viewers. They had no documentation, no SDKs, and very little technical knowledge — just a mix of curiosity and stubbornness. Out of that came the earliest scene of amateur creators, one that planted the seeds for the entire modern modding movement.
The Birth of ROM Hacking Culture
At the core of 90s ROM hacking was the emulator. Projects like NESticle (1997), SNES9x (1996), and Genecyst (1997) not only let you play old games on a PC, they exposed game memory in a way that was never possible on the original hardware. NESticle in particular became notorious not just as a fast and accessible emulator but as a hacking tool. It included a built-in tile editor, which allowed anyone to literally redraw sprites in real time. Mario could be turned into Bart Simpson, Link could be swapped with Sonic, and text could be edited by poking around in the game’s ROM file.
This accessibility turned hacking into a kind of playground. You didn’t need to be a professional coder to take part. All you needed was a copy of the ROM, a hex editor, and a willingness to experiment until something changed. Kids discovered they could swap palettes, change difficulty, or even insert crude new dialogue. What started as a curiosity quickly snowballed into a subculture.
Hacks, Translations, and “Hardtypes”
Not all hacks were created equal. On one end, there were “bad hacks” — half-finished sprite swaps, edgy teenage text edits, or joke versions where Mario flipped the middle finger. On the other end were ambitious translation projects and difficulty overhauls.
One of the most famous hacks of the 90s was RPGe’s fan translation of Final Fantasy V (1997). Square never brought the game to the West on the SNES, so fans painstakingly dumped the script, translated it line by line, and inserted English text back into the ROM. For many Western players, this was the first time they could play a major Japanese RPG otherwise locked behind a language barrier. It set the stage for an entire wave of fan translations, including Seiken Densetsu 3, Mother, and Bahamut Lagoon.
Alongside translations came “hardtype” hacks. These modified the game’s code to raise difficulty. Enemies hit harder, resources were scarcer, and cheap deaths became common. Players who had mastered their childhood favorites flocked to these hacks to experience familiar worlds through a punishing new lens. This spirit would eventually inspire the Kaizo Mario community in the 2000s, which exploded into a YouTube and Twitch phenomenon.
The Underground “Bad Hack” Scene
As much as translations and hardtypes shaped the culture, the other side of ROM hacking was pure chaos. NESticle’s tile editor made it too easy to draw crude images, swap heads, or insert lewd jokes. One notorious hack of Final Fantasy II was subtitled “Dark Shadow Over Palakia,” a fan edit full of profanity and “adult” humor that has become infamous for all the wrong reasons.
These early hacks may have lacked polish, but they reflected something important: the idea that fans could take ownership of the games they loved. They weren’t passive consumers anymore — they could reshape a classic however they wanted.
Communities Form Around the Craft
The rise of websites like Zophar’s Domain (1996) (Zophar's Domain was created in 1996 by Brad Levicoff) gave hackers a central hub. Here they traded tools, uploaded hacks, and shared tutorials. For many, this was their first taste of community-driven digital collaboration. People taught each other how to trace pointers in hex code, how to adjust palette tables, and how to work with compressed graphics.
The culture was DIY in the purest sense. Without official support, hackers created their own documentation and standards. The arrival of Cowering’s GoodNES tool, which cataloged “good dumps” of NES ROMs, introduced the idea of curating a “clean” library of verified games. This early obsession with accuracy would later influence preservation efforts by groups like No-Intro and modern digital archiving projects.
The DNA of Modern Modding
What makes 90s ROM hacking so significant is how clearly it prefigured the modern modding ecosystem. When Bethesda releases a Creation Kit or Valve hosts Steam Workshop, they are essentially legitimizing practices that fans were already doing decades earlier in makeshift ways.
The impulse is the same: take a finished game, bend it, twist it, and add to it until it becomes something new. Whether that is replacing Mario sprites with Mega Man or adding an entire new quest line to Skyrim, the culture flows from the same root. The 90s hacking kids who learned hex code and palette swapping often went on to become professional programmers, designers, or translators.
ROM hacking also showed the power of community curation and distribution. The act of downloading a fan translation patch and applying it to your ROM mirrored the workflows we now see with Nexus Mods installers or Steam one-click modding. In many ways, the complexity has decreased, but the spirit has remained intact.
Preservation and Legitimacy
It is worth remembering that without emulators and ROM hacking communities, many games would have been lost to time. Nintendo and other publishers were not preserving unreleased prototypes or localizations that never left Japan. Fans did that work, even if it lived in a legal gray zone. Projects like the leaked US prototype of Mother (later released officially as EarthBound Beginnings) became accessible only because of this underground movement.
Critics and companies often painted hacking as piracy, and sometimes it was. But it was also cultural preservation, translation, and experimentation. By the late 1990s, the groundwork was laid for how the industry itself would later adopt modding as a mainstream selling point.
Conclusion: From Basement Hacks to Mainstream Mods
The story of ROM hacking in the 90s is not just about crude sprite edits or harder bosses. It is about fans taking the first steps toward a participatory gaming culture. Before corporate-sanctioned modding kits and Steam integration, kids with hex editors were already doing the same thing, fueled by passion, curiosity, and the thrill of bending games to their will.
Today we take modding for granted. But the structure, the culture, and the workflows all trace back to the messy, vibrant ROM hacking scene of the 1990s. Without it, there would be no Kaizo Mario, no Nexus Mods, and perhaps no recognition of games as platforms for communities to build on rather than closed-off products.
