Yu-Gi-Oh! The Duelists of the Roses: a byte-matched PS2 decompilation

This decompilation reconstructs the NTSC-U PS2 release of Yu-Gi-Oh! The Duelists of the Roses in C, covering SLUS_205.15 and 762 code modules. Its make check target compares rebuilt files byte for byte with the user's originals. The author reports that the main executable is in C while module functions remain partly in assembly.
