G-Engine: rebuilding Gabriel Knight 3 around its original data

G-Engine reimplements the engine needed to play Gabriel Knight 3: Blood of the Sacred, Blood of the Damned on Windows, macOS and Linux using the original game's data. Its C++ code parses Barn asset bundles and handles the game's Bink and AVI videos; the source credits earlier reverse engineering of BRN, BSP and ACT formats. The author reports a completable game with remaining bugs and missing noncritical features.
