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,

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. 1 P. w t$ |+ k. U* \
Origonally thought to be just an arcade/jamma compatible system, this is now know to be around twice as powerfull as the home variant,
( C% G, T3 o5 [( h: F1 U; HThe 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.6 @" B, f4 u& m% u0 m
Developement 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.

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.: L6 D( b C& f# Y, o* y
