A playable port and modding hub for the PSX game Legend of Legaia (1998, Sony, NA SCUS-94254), standing on Ghidra-traced reverse engineering of the retail disc. The disc's formats are documented byte-by-byte with provenance back to traced retail functions, Rust parsers extract every asset, and a from-scratch engine runs the game's own scenes, scripts and menus - natively on wgpu, and in your browser via WebAssembly. On top of that sit a disc randomizer, a translation toolchain, and a project site full of interactive viewers that run entirely off your own disc image.
