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,

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.% A4 ^) `8 }' u2 [0 Z& x. J
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. ) F7 m {* h- H7 t w* q) N, k
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.
