What you are using (Windows, Android, Steam Deck)? Which specific Saturn core you prefer to run?
If you no longer have a working Saturn, some archival groups have released hash-verified dumps. The community standard files are:
The BIOS is corrupt, or the core cannot find the "CD Block" image. This often happens with multi-track games. Fix: Open the .cue file in Notepad. Ensure the bin file name inside the cue matches the actual file name EXACTLY (including capitalization on Linux).
Without the correct BIOS, Beetle Saturn is a brick. With it, the Saturn library becomes a paradise of 2D sprite scaling, 3D experimentation, and some of the rarest RPGs ever made.
Acquire the legal dumps of your physical SEGA Saturn console hardware.
