Resident Evil 4 (GameCube) – complete byte-identical decompilation to C/C++

Summary

The project releases a full, byte‑identical C/C++ decompilation of Resident Evil 4 for GameCube, reproducing the original binaries down to every byte. It ships with build scripts, verification tools, and detailed documentation of the matching process.

Provides a complete, byte‑identical C/C++ reconstruction of Resident Evil 4 GameCube debug build, matching main.dol and 114 REL overlays.
Build uses SN GCC 2.95.3 and Metrowerks CodeWarrior; verification via SHA‑1 hashes and per‑object byte‑by‑byte diff tools.
Source totals ~555k lines, 15641 functions; only 644 compiler‑diff comments and 231 asm‑generated instructions remain.
Includes a suite of scripts (configure, ninja, bytecmp, fdiff, asmcheck) and extensive docs on matching methodology.

Reverse engineers, console developers, and preservationists can study a real-world legacy game engine and compiler behavior without proprietary binaries.

A Canadian hobbyist spent four years chemically decapping and optically dumping the PS2’s CXP102064 MechaCon security chip, finally releasing its ROM. The dump opens up software disc backups, modchip development, and future low‑level emulation of the console’s security mechanisms.

Stars!VM is a 32‑bit Windows executable that embeds a custom 80286 emulator and a Win16‑to‑Win32 bridge to run the 1995 4X game Stars! without any external emulators. The author adds differential fuzzing, hot‑routine patching, I/O buffering and asset compression, achieving about a 2× speedup in turn generation.

The author built zSST, a SystemVerilog recreation of the 3dfx Voodoo 1 graphics chip, and integrated it with a z486 CPU on a Xilinx KV260 to run DOS games with original 3D rendering at 100 MHz. The post details the fixed‑point pipeline, stage breakdown, and memory subsystem needed to sustain one pixel per clock.

The author used the AI tool Fable 5 to generate a 4‑layer RP2350 development board for an E‑ink display from a short English description and ordered it from JLCPCB. While the AI handled component placement, it left many DRC errors and routing gaps, requiring manual fixes and highlighting the limits of current AI‑driven PCB design.
