SI Electronics unveiled its new System Board Y2 arcade hardware today. The hardware will go on display at the upcoming AOU Amusement Expo event ahead of its full Spring distribution.

System Board Y2 makes use of SI's internally developed "YATA-2" technology, a single chip that contains a 32bit RISC CPU at 266 MHz, a graphics engine housing 2D/3D imaging and video decoding, and an I/O controller.

Specs provided by SI list graphic capabilities of 250,000 sprites per screen, one million polygons per second, and SVGA (800x600) 30fps movie output. The system offers 32 channel sound. As media, the system uses exclusive ROM carts with a maximum capacity of 1.7 gigabytes for program data and 256 megabytes for sound data.

The device already has its first game on the way. AQ Interactive's recently announced Higurashi no Naku Koro ni Jan, a mahjong version of a sound novel series, will be powered by the new board.

This game, along with the System Board Y2 board itself, will be on display at AOU 2009, which opens its doors at the Makuhari Messe in Chiba on Friday for the press and Saturday for the general public.
