Yes, for 99% of use cases (Flycast, RetroArch, Redream). For hardware ODEs, check compatibility first (GDEMU requires a tool to convert CHD back to GDI internally).
(Gigabyte Disc Image) is a perfect 1:1 rip of the original 1GB GD-ROM, containing every bit of data as it was intended by developers. GDI (Best for Emulation/ODEs): dreamcast gdi best
