NGC主机互换大型机板TRIFORCE是任天堂、namco和世嘉3个好基友合作而成的街机机板。而这个机板和NGC也是亲兄弟，很多参数和NGC都一模一样。但有許多不同的地方，包括比GC大一倍的1T-SRAM容量、增設世嘉的GD-ROM及可升級的RAM模組等,也能让家用主机与大型电玩相互间的移植更具效更具效率.性能方面在软件展示中已经获得了专业人士的认可，0 \) ^+ y& U. N) c2 a

Notes : Conceived as a joint venture between Sega, Namco and Nintendo to produce a low cost arcade system, with even talk of multiplayer games between people in arcades and home consoles using the GAMEFORCE network.
9 ?' X4 c/ e6 X* _5 u; y- GOrigonally thought to be just an arcade/jamma compatible system, this is now know to be around twice as powerfull as the home variant, " {1 Z$ d4 h- g# M! }4 m# K4 F, B" L
The only details being leaked that it has 48 MB of 1T-SRAM in place of the standard "cube's" 24, so to this end I have taken out all of the specs for the system an just replaced it with what we know about it so far.
8 W1 s; p+ \5 i' h) B0 P6 iDevelopement Notes : Sega's AM4 dept. re-wrote the Naomi development toolkit to be fully compatible with the Triforce, making development for this system very easy, as both Sega and Namco are familiar with it. 6 L9 d6 m$ t: Y+ k) p9 v) j
Hardware Notes : Sega have made the Naomi GD-ROM drive compatible with the triforce as well, it is unknown if this will be used by Namco and other manufacturers as well. k8 f. u7 p1 J7 ~
Versions : The 2 versions are the "A" and "B" versions. The "A" version has a Naomi stype Dimm board on top, where the "B" version has built in internal RAM.
