Ace Combat 3: Electrosphere English translation
エースコンバット3 エレクトロスフィア
Project Nemo's long-running fan translation brings the full story-driven Japanese version of Ace Combat 3 to English, across both discs and all five routes.
What's translated
Project Nemo started this project in 2009 to make the complete Japanese edition of Ace Combat 3 playable in English, rather than the trimmed-down Western release. Their patches cover both discs: the in-game subtitles for all 52 missions, radio chatter and the story, with later updates adding edits, extras and translated on-screen signs in the FMVs. The current release, v0.9b3 "Warchild", came out in March 2026 after a series of beta updates since 2023.
Playing it
The game branches into five routes with their own endings, so saving before each decision point saves a lot of replaying. Clearing every route unlocks the epilogue and a free mission mode, and good mission ranks unlock extra aircraft for that mode.
The patches are applied to your own copy of the Japanese discs, following the team's instructions on the official page.
