Preloaded, plug-and-play game collections are intended for use with modified Dreamcast consoles with a GDEMU installed. These will not work on an unmodified console. Includes a 512GB MicroSD, with full size SD adapter. The Even More Homebrew variant has everything on the US Collection plus hundreds more Homebrew titles, AtomisWave ports, and Beats of Rage. Many of them are very bad, as they are fan made, but we've included all we can find! (635 discs in total.)
