now the question is, what is House Of The Dead 4 running on:

something like an Xbox360-based board
(i.e. Chihiro 2 ?)

or

a new high-end PowerVR Series5 board
(i.e. NAOMI 3, Lindburgh, System SP)

> now the question is, what is House Of The Dead 4 running on:

Its running on Sega's new custom arcade hardware (with the custom powervr chip IT designed for them)

The official name for the hardware hasnt been released yet, I called it Naomi 3 on System16 due to the page needing to be called something ;)

Six...

System16 - The Arcade Museum

cool, I look forward to the PC port a year or three after the XBox360 version :-p
