Tip

New here? Start with Getting Started → Overview → format inventory. Editing data files? Jump to MM2ED Editor. Tracing combat or scripts? Combat Overview · Combat System · Event Script Opcodes. Audio? Audio Sounds Music.

Important

Endianness — MM2 .dat multibyte fields are little-endian on disk (matching our codecs and Blitz3D editors). The 68000 runtime may byte-swap after load — trace ASM before assuming otherwise.
