Atomic Bomberman (Egerion)

Game: Atomic Bomberman → (Windows, 1997)

A clean-room reimplementation of Atomic Bomberman (Interplay, 1997) in C++20 with SDL3, called Open Bomberman. It is a deterministic 20 Hz simulation that reproduces the arithmetic of the original executable, learned by reverse engineering, and it loads the original graphics, sound, and music at run time from your own install: the repository contains nothing from the game. According to the README it is playable, with movement, bombs, kicks, punches, grab and throw, the nine diseases, closing walls, conveyors, warp holes, and trampolines, random stage rotation, and a scheme editor. It adds online games of up to ten machines, with a lobby code or a public list, a direct UDP path with a relay when the NAT refuses one, and GGPO-style rollback netcode with no input delay. Version 1.0.0 (August 1) publishes OPEN-BM95.exe. The README says all of the code was written by Claude Code, and 95 of its last 100 commits list Claude as a co-author.

You needAn original Atomic Bomberman installation; the game data is not included. To build, CMake 3.25 or newer and a C++20 compiler (Visual Studio 2022 on Windows, any on Linux and macOS); SDL3 is fetched at build time.
