The Sega System SP, also known as the Sega Aurora, is an arcade board built from a Dreamcast/NAOMI-based system-on-a-chip with enhanced base components.[1] Whilst it uses a similar architecture to the Sega NAOMI, the actual system is different, running a bespoke version of Linux 2.6 and having all of the controls wired directly to the main board, meaning that there is no need for a separate JVS I/O board.
