Boku Doraemon: Dreamcast executable and model reconstruction

Boku Doraemon maps the Japanese Dreamcast game's 1ST_READ.BIN, generates a matching assembly baseline from an owner's disc, and tests C function candidates for equivalent calls, memory writes and results in an SH-4 interpreter. Its committed model map records recognized models, textures, sounds and offsets. The author reports 123 equivalent functions, all from locally supplied SDK source at this checkpoint.
