This is a fascinating article, Ross. I had never heard of the System SP before reading this. Shame about your 3DS though - cheapskate XD

Great work Ross, though there is one stone you left unturned in this feature. I shall endeavour to cover it in another article in the near future.

Furthermore, you could argue that Chihiro and Triforce are semi-close second cousins to the Dreamcast family, since the both used the GD-ROM system? If you wanted to end on a less sour note.

I'd be interested to hear what stone I've left unturned. Hmm...what could it be? Yeah, using a GD-ROM drive alone isn't enough for me to be honest. Chihiro and Triforce are their own thing. The Lindbergh on the other hand, as the true successor to Naomi, now that would be interesting. I did consider a quick piece on the other arcade hardware out their that birthed games that would eventually wing up on the DC; Model 2/3, CSP2 etc etc. Maybe someday...

good read, thanks.
about Triforce/Chihiro conection - it is, SP have same network subsystem (AMD AU1500 based) but integrated on main board.

simply speaking SP is Naomi with integrated:
+ 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 ^^^above^^^
so SP is later and cost optimized/reduced Naomi iteration.

Aurora... it is completely different beast, developed by SI Electronics Inc, former Sammy subsidiary.
it was cheap single chip solution, mainly targeted for pachinko and similar gambling/redemption machines.
its not known if there was developed "regular" arcade games for this platform.

If you look online, you'll find many sites listing the system SP as the Aurora, even with pictures of the SP and lists of its games (Sega Retro and Wikipedia are two such examples off the top my head). My intention was only to clear that misconception up. Thanks for the extra info about what the Aurora really is.

Which titles were released on the Aurora out of interest? Any pictures of the actual system out there on the web?

if I look online - I see many incorrect information about not that good known gaming systems (many "honorable" sites for example says Naomi2 have 2 SH4 CPUs lol).
as I see the roots of this story - in the past there was no information about SP, even of its existence, but there was number of know games like DinosaurKing, Love&Berry, etc and known system - Aurora. so some person listed that games as form Aurora platform.
until I've researched (and emulated) this SystemSP few years ago, wrote tech specs, fixed information about it at system16, made more-less full game list, etc.
but some sites like Wikipedia and others may still have outdated and incorrect information.

about Aurora - sorry, have no information about games, have seen (looking trustable) tech specs at beyond3d, in the net also can be found Sega's document/presentation from some Linux event. that's all I know. as was said - it was created by SI Electronics, Ltd.
earlier SI E. was involved in Atomiswave development (it seems they was one main creators)
and later, after they left Sammy Holdings, in 2009 they made "System Board Y2" platform, mainly known for "King of Fighters 2002: Ultimate Match" game.

Even System 16 lists the Naomi 2 specs as:
"CPU : 2 x Hitachi SH-4 32-bit RISC CPU (200 MHz 360 MIPS / 1.4 GFLOPS)
