1080 Snowboarding: matching Nintendo 64 decompilation with USO overlay analysis

1080 Snowboarding decomp reconstructs Nintendo 64 game code in C and C++, including its custom USO overlays and Yay0-compressed segments. The author reports a byte-identical ROM build, while its progress table distinguishes matched C from partial work and assembly-backed portions. The project also documents recovering overlay relocation targets through emulator-assisted symbol dumping.
