# b0r3doom engine source

The engine behind https://b0r3d.org/b0r3doom/ is Dwasm (PrBoom+ / PrBoomX),
GPL-2.0, with b0r3d.org's changes. This folder is the source offer for it.

| file | contents |
| --- | --- |
| `b0r3doom-engine-<build>.tar.gz` | the complete source tree the engine was built from: upstream at a pinned commit, changes already applied, plus `B0R3D-BUILD.txt` with the exact build steps and settings |
| `b0r3doom-engine-<build>.patch` | the changes on their own, against that same upstream commit, with a header describing each one |

`<build>` is the engine build id: the first 12 hex of the shipped
`index.wasm`'s SHA-256, the same id b0r3doom's launcher uses to version its
engine files. Each engine rebuild gets a new pair here; old pairs stay.

## Provenance

Upstream is https://github.com/GMH-Code/Dwasm. Each archive's
`B0R3D-BUILD.txt` names the exact commit, the toolchain versions, and the
SHA-256 of the shipped `index.wasm`, `index.js` and `index.data`, so a
download of the live engine can be checked against it.
