piney_apples: reconstructing the four .hack PS2 games in Rust

piney_apples rebuilds the engines of .hack//Infection, Mutation, Outbreak and Quarantine as a native Rust program. It replaces game loops, scripts, battles, rendering and audio, generates tables from users' North American PS2 discs, and compares selected Rust functions with original code run in a project interpreter. The project reports that players reached the endings of all four games.
