Digimon World DS: matching Nintendo DS decompilation

Digimon World DS reconstructs the North American Nintendo DS game's ARM9 program and overlays as matching C source. Its dsd-based build takes code still awaiting decompilation from the user's ROM, links recovered functions into the modules and checks the output byte for byte; the author reports 2,386 of 3,665 game functions in C as of October 2026.
