Open Reverse-Engineering Project
A clean-room reimplementation of Jimmy Neutron: Boy Genius (2002) and its sequel — rendered faithfully by capturing the original game's Direct3D 7 output, and playable right here in your browser.
🎮 Boy Genius Play
The original game's Retroville, running as WebAssembly. Walk around Level 1.
🚀 vs. Jimmy Negatron Play
The sequel on the same engine — 22 levels, items, vehicles, gameplay.
Runs entirely in-browser (no install). Best on a desktop browser; touch controls work on mobile.
64-bit Windows 7 or newer. Experimental QA build — bug reports welcome.
🗂️ Asset Library
Search & download every asset — 1,800+ textures, 2,000+ meshes, 1,000+ audio clips, all level data — in original & modern formats (PNG · ASE+glb · WAV · GAM), individually or in bulk zips.
🧩 JNvsJN Asset Library
Search & download the sequel's full asset set — 2,400+ textures, 389 Granny (.grn) meshes (glb + 3D viewer where convertible), 1,000+ audio clips, all level data — in original & modern formats, individually or in bulk zips.
🎨 Custom re-renders
One-off experiments — original game meshes wearing canvases they were never meant to. First up: the Level 1 car in the jeep's skin.

📖 Project history
The whole story — from "unlock the resolution" to faithful D3D7 replay.
🧭 Architecture guide
How the codebase fits together, subsystem by subsystem.
🛠️ Native port update — behavior coverage + story
The latest changelog: per-object behavior coverage (now 90/93 used types), the campaign's SCENE story machine, Goddard, and the new browser Campaign toggle + keyboard fix. Links back to the N1–N5 update.
🔬 Audit & status report
Where the reconstruction actually stands: an evidence audit of the project’s own process, what a follow-up measurement session resolved against the original binaries, and what still needs fixing.
🗺️ Asset Catalog & road to parity
Post-mortem of the new asset catalog — what it records, why it reshapes the native Linux port, and the concrete path to full parity with the 2002 original.
