Reverse engineering notes, format documentation and analysis tooling for Infinite Undiscovery (tri-Ace / Square Enix, Xbox 360, 2008) and its ASKA engine.
Structural documentation of Tales of Phantasia on SNES (1995) and GBA (2003): ExHiROM mapping, the in-house LZSS block codec, the SPC700 boot payload, and what the GBA rebuild inherited from the cartridge.
File-format and engine documentation for Tales of Crestoria (Bandai Namco, Android, 2020-2022), built on tri-Ace's ASKA engine: SLZ/Zstandard containers, ISF packages, ETC2 textures, Cocos Studio UI, Ogg Vorbis audio, GLSL shader archives, and a hollowed-out native library.
