Codenamed "Samurai" The Sega Hikaru was the successor to the Model 3. The CPU was a 2× Hitachi SH-4 CPU at 200 MHz, the GPU was a Custom Chipset and NOT related to PowerVR at all. It had 100MB of RAM.

There is also an [https://github.com/aaronsgiles/Gaelco3D inactive emulator] for the unrelated earlier Gaelco 3D system, and [http://adb.arcadeitalia.net/dettaglio_mame.php?game_name=gaelco_serial&search_id=&lang=en MAME] [https://github.com/mamedev/mame/blob/master/src/mame/gaelco/gaelco3d.cpp supports] that one.
