THE REVERSE ENGINEERING COLLECTION
50 case studies from 182 curated resources, with documented reconstruction methods, scope, and original evidence.
These cases are part of the curated total and appear once under their primary subject, with all target labels retained. Source review does not imply independent runtime verification or REA involvement.
2 cases
REA’s documented teaching case inspects the HTTP t-rex-runner edition and reconstructs its speed-update rule. A separate controlled original-game check and a new demonstration compare update counts, including the floating-point step that crosses the nominal speed threshold.
Documents a website-rebuild-skill case that decodes browser-delivered React Server Component Flight streams, reconstructs a buildable Next project and compares its output with a captured site. The reported rauchg.com campaign uses route-tree comparison and module-reference mapping; the new server source is inferred from observable output.
24 cases
Recover one sound-pan function from instructions and constants; upstream cites 3,205 cases and a 63-byte match.
Inspect a 16-bit PC-98 DOS helper and relate its angle calculation to a pinned reconstruction and historical compiler checks.
Reconstructs Super Mario 64 DS functions as C/C++ and permitted assembly primitives, comparing compiled output with a user-supplied cartridge dump. Independent relocation-destination checks strengthen the matching gate; integration into the PC port is tracked separately.

It distinguishes intended retail 3.1 behavior from community-patch research and deliberate modern changes, and separates synthetic checks from tests requiring original game data.
Reconstructs the original Japanese Touhou 8 version 1.00d against its binary and original compiler, then adapts the recovered code for other platforms. Source presence, strict function matching, whole-executable identity and playable-port checks are recorded as different milestones.
Uses N64Recomp to translate Majora’s Mask into a native application and RT64 for rendering. The project separates static recompilation from source decompilation while reusing decompilation headers and selected functions for patches and enhancements.
Reconstructs readable GOAL code from the original Jak binaries and compiles it with a new GOAL compiler for modern PCs. Its workflow combines a specialized decompiler, manually supplied type information, asset extraction and an interactive development runtime.
Reconstructs the English LEGO Island 1.1 source for its original 32-bit Windows target. The project distinguishes function-comparison reports, ReproBit’s reported byte-identical retail rebuilds and ordinary developer builds; its modern portable adaptation is a separate repository.
The author uses REA’s Ghidra workflow to investigate the DOS Ski or Die binary, document Snowball War rules and rebuild that one minigame in Rust with SDL2. The public notes distinguish recovered tables and mechanics from approximations and deliberate presentation changes.
Converts the reverse-engineered Space Cadet pinball game into compilable C++ for desktop platforms. The README identifies the Windows XP executable and public PDB, a Full Tilt executable, and the work of recovering structures, naming variables and adapting the decompiled routines.
Reconstructs Super Mario 64 source for Japanese, North American, European, Shindou and iQue releases. Its build files distinguish original-ROM hash comparison from nonmatching or modified configurations, while source naming and documentation remain ongoing.
Builds an unofficial Sonic Unleashed PC port by statically recompiling Xbox 360 PowerPC code with XenonRecomp and Xenos shaders with XenosRecomp. The port adds modern display and modding options while documenting original-engine limits and remaining compatibility issues.
Provides an independent engine for playing Morrowind and an alternative editor, OpenMW-CS. It loads original game content through its own runtime and documents script and mod compatibility differences; it is an engine replacement rather than a recovered Bethesda source tree.
Translates reverse-engineered Driver 2 MIPS routines into C/C++ and uses Psy-X/Psy-Cross to adapt PlayStation interfaces for desktop systems. The project documents symbol-assisted Ghidra/IDA work alongside intentional bug fixes and gameplay changes.
Builds a modern Diablo and Hellfire port on the Devilution reconstruction, with platform support, bug fixes and optional quality-of-life features. The project documents the original symbol-assisted reconstruction and includes selected dungeon-generation and saved-game regression checks.
A native desktop reconstruction of the 2019 Switch version of Link’s Awakening using static recompilation. The author attributes most code, tooling and reverse-engineering work to Claude Code with human direction and review.
Runs Spider-Man Remastered and Arkham Knight together, streaming Gotham collision into Spider-Man’s physics world and compositing his rendered frame into Arkham. This experimental runtime bridge is not a recovered standalone game or new engine.
