What is GD-ROM on Dreamcast?

Sega's 1999 disc format: CD-sized, but 1.2GB capacity via variable track density. Inner audio-like for copy protection, outer data-packed.

Does Linux run Dreamcast games natively now?

Not emulation-free — still needs Flycast/Reicast. But kernel GD-ROM support means perfect disc dumping on Linux hosts, no Windows VM.

Floppies: zero modern use, bloat code. GD-ROM: tiny footprint, enthusiast joy. Forks preserve floppies anyway.
