# Virtua Tennis: a disc-local Dreamcast decompilation

> Virtua Tennis decomp reconstructs the Dreamcast game's executable from a user-provided disc, first establishing a byte-matching assembly baseline and then substituting C for game functions. Its tools generate function tests and asset maps for models, textures, text and audio. The author reports C has been written for every function with a C form, with behavioral equivalence as the completion criterion.
