# SCD Disasm: Sonic CD disassembly

> SCD Disasm reconstructs Sonic CD's Sega Mega CD program files from disassembly, initially using the V0.02 prototype. It organizes reused engine functions into shared source files with linker scripts for the disc files; the author reports that the resulting binary objects can be assembled into an ISO that runs in an emulator.
