The Dreamcast had a boot ROM which provided various system calls for games to use.
By default, redream will attempt to high-level emulate this boot ROM. However, this process is currently not perfect, resulting in some games failing to boot. If you have a real boot ROM you’d like to use instead, it can be placed in
$HOME/.redream/boot.bin and will take priority over redream’s HLE implementation.
