Final Fantasy VII Rebuilt for ARM64 Android: Code Written by Claude Over a Weekend

⚡ The 5-Second Summary

• Final Fantasy VII from the Steam version is statically recompiled into native ARM64 code for Android — no emulator, no Wine, no FEX.
• Rendering goes through FFNx on Vulkan (default) or OpenGL ES; the project was built for the dual-screen AYN Thor, but other handhelds and phones are claimed to work too.
• There are no game files in the repo or the APK: the app recompiles your own ff7_en.exe once, right on the device.
• The author warns upfront: all the code was written by AI (Claude in Claude Code) over a weekend, with no line-by-line human review.

🔍 What Happened

A repository called bhuiyah/ff7-recomp-android has been made publicly available — 116 commits, the project is named FF7Recomp. This is not an emulator: the PC version of Final Fantasy VII from Steam is statically recompiled into a native ARM64 binary for Android. The author built everything for the dual-screen AYN Thor, but writes that it can also run on other Android handhelds and phones. The repo and APK contain neither game code nor data: the app takes your ff7_en.exe, recompiles it once on the device, and nothing derived from the game leaves it. The project is not affiliated with Square Enix.

Here's how it works: the launcher imports the game files, installs mods from 7th Heaven catalogs (.iro, .zip, .7z), and lets you set the mod load order and their options. Alongside that — save states, achievements, 30/60/120 FPS, 16:9, gamepad support (A confirms, B cancels). Languages include English, French, German, and Spanish: Settings → Language, with the selection depending on your Steam copy. On-screen buttons (D-pad, A/B/X/Y, L1/L2/R1/R2, Start/Select) are configured in Settings → On-screen controls (Automatic, Always, Off) and hide automatically when a gamepad is connected. There's also a CRT filter and a renderer choice in Settings → Display, portrait mode on phones, and party status output on the Thor's bottom screen in Settings → Screen.

🧠 Our Take

Static recompilation of old games isn't news in itself: the credits honestly list pcrecomp, nfsu2-recompiled, FFNx, 7th Heaven, and bgfx. What's new here is different — the rebuild pipeline runs on the device itself, and all the glue code was written by an AI agent over a weekend. Our assessment: this is no longer "a chatbot scribbled a script," but a full-fledged project with CMake, patches, an Android port of the renderer, and documentation. That's exactly why the repository is more interesting than just another way to play FF7 on the subway.

What this changes for someone with a phone: modded FF7 without an emulation layer and without Wine gymnastics. For the AI-code conversation, it's a precedent: the author didn't bury the disclaimer at the end but put it in the README, honestly said "we didn't check it line by line," and added that the commits are signed by Claude. We think this is the right disclosure format, but it doesn't erase the question: you're running an unverified app that reads and recompiles your game files.

Who wins: the FFNx and 7th Heaven ecosystem — it gets another reason to be remembered, while mod makers remain the authors of "the hard parts." Who loses: official mobile ports, which look increasingly modest next to a free alternative. And possibly the author himself — if the project drowns in bug reports he physically can't handle alone.

⚠️ What We Don't Know

Everything we know comes from the README. There's no list of confirmed devices, no performance benchmarks, no independent tester reports. The author states outright: it works on his Thor, beyond that — "rough edges and bugs." It's unknown how non-Steam copies of the game will fare, how specific mods will behave, and how safe an app is that you give access to your files.

Prediction: within a quarter, there will either be a fork with fixes from other people, or a public report of a successful run on a device other than the AYN Thor.

Disclaimer: a single source — the author's README; no independent tests or code audits exist.
