Introduction
The long-rumoured English translation of Compile's Shadowrun for the Sega CD has arrived in the retro scene, led by homebrewer Erebus — better known as MadMorigan.
The release, published in early September 2026, restores English text, menus and dialogue to a Japanese Mega-CD port that has until now remained largely inaccessible to non-Japanese players.
In the days following that release, other community translators surfaced with their own patches; several of these projects disclosed using AI tools during their workflows, prompting discussion about machine translation, human editing and community standards.
What was released
MadMorigan's translation localises the Sega CD edition of Shadowrun — a distinctive adaptation of the cyberpunk RPG that differs from the SNES and Genesis versions in tone and mechanics.
Testers report the patch can be burned to disc for play on PAL-enabled hardware and that MadMorigan is working on an NTSC build for U.S. systems.
The project promptly brought renewed attention to earlier, long-running efforts, including work by Iwakura Productions and an independent patcher known as RetchE.
Developer statements on AI assistance
RetchE, whose own localisation has been shared publicly, stated that their release is a machine translation that has undergone human editing, corrections and playtesting to improve readability and to address issues discovered in testing.
They emphasized the patch is not an official localisation nor a professional human translation and acknowledged that some wording and nuances may still require refinement.
RetchE also explained a decision to employ the same general approach as other community translators: they said they planned to pass their text through AI to align results with the wider community and to reduce conflict, adding that their goal was for fans to enjoy translations together regardless of the tools used.
Separately, the individual behind MadMorigan’s English patch disclosed using the Claude assistant during their process.
They reported combining Claude’s outputs with manual playthroughs and several iterations of edits to address issues such as spacing and presentation.
The translator noted that while GenAI is not a term they commonly use, they rely on AI and large language models (LLMs) in professional settings and typically refer to them by product name.
Context and community impact
The Sega CD Shadowrun localisation has been a stop-start effort for years; multiple homebrew projects faded before completion.
The arrival of an accessible English patch for this Mega-CD release marks a significant moment for preservation-minded fans and retro collectors.
Transparent disclosure from modders about methodology — including the use of machine translation and LLM tools like Claude — has shifted community discussions toward quality, attribution and best practices for patch distribution.
As interest in classic titles continues among modern platform owners, conversations about official re-releases on services such as the Nintendo Switch eShop and other digital storefronts remain part of a broader debate on preservation and accessibility.
For now, the community-driven translations make this unique Shadowrun entry playable in English on legacy hardware, while also prompting deeper dialogue about AI’s role in fan localisation.
