Sega Aurora (Not exactly the same as the "Sega System SP") is a highly integrated hardware platform that Sega Sammy developed to power amusement devices like their pachinko/pachislot machine displays and arcade games and to also be sublicensed to outside manufacturers who are looking to build multimedia portable and embedded systems. It was developed by SI Electronics Inc, a former Sammy subsidiary. It was introduced in 2004 and is primarily based on an enhanced Dreamcast hardware. The name "Aurora" derives from a top secret code name that Sega Enterprises, Ltd. used during the development of Sega Saturn in the mid 1990s.[1] As SI Electronics left Sammy Holdings after being acquired by Kaga Electronics in July 1, 2008, they made the "System Board Y2" platform in 2009, mainly known for the game "King of Fighters 2002: Ultimate Match".

Aurora is made of a Renesas System-on-Chip named SH3707 which incorporates the technologies of partner companies that worked on the Dreamcast and related systems. Its CPU core is Renesas SH-4 based technology with FPU clocked at 300 MHz. Its GPU core is a PowerVR MBX accelerator with VGP co-processor running at 150 MHz. On-chip audio and video hardware supply the system with the capability for ADPCM and MPEG1/2/4 respectively.


Aurora System SpecificationsEdit

Sega System SPEdit

It is different to the Sega System SP, which had a common misconception of being the same system as the Aurora hardware, even though they were both based on a similar CPU (However, those CPUs had different brand names and frequency speeds). The System SP was optimized cost-wise as in being a simpler iteration of the NAOMI hardware. In simple terms, the SP is akin to Sega NAOMI with the following integrated hardware features:

  • Flash ROM board, same as later cartridge games like Dynamite Deka EX or Melty Blood Actress Again
  • Network board, same as used in Triforce or Chihiro
  • CF card interface
  • IO chip, game controls wired directly to main board
  • JVS host MCU was removed, because of the above feature
