62.3、ST-V

ST-V是SS主机的互换基板，其最大的特色就是不仅可以进行3D多边形运算，同时依然兼顾了传统的2D处理。在3D方面，世嘉的目标是超越MODEL1的水准；至于2D处理，则是具备凌驾于SYSTEM32的表现力——后者应该是当时为止机能最强的2D基板了。实际证明，ST-V确实是做到了这两点：在街机领域，它被称为MODEL1.5，有着《十项全能》、《VR战士KIDS》、《暴烈刑事》等3D名作，DATA EAST、SUNSOFT、ATLUS等厂商也纷纷把新的2D对战游戏从MVS基板提升到ST-V；而在家用机上，SS主机对于CPS2、MVS、TAITO_F3以及CAVE、PSIKYO等基板的移植度也是有口皆碑。
但可惜的是，向来以街机为主要业务的世嘉已经有了MODEL2这样的主力基板，这才是世嘉的运作重点。在3D游戏方面ST-V达不到那样的表现力，也得不到足够的开发资源；2D方面，世嘉本身昔日引以为傲的活动块缩放技术已经被多边形处理所取代，至于纯2D游戏，向来就不是世嘉的长处，而CAPCOM、SNK、TAITO等大厂都有着自己的现役基板，KONAMI和NAMCO更是对手阵营的主要支持者，于是，ST-V就只能更多的依靠那些二三线的第三方厂商来发挥了。

Other infos : This board is Jamma and uses a standard resolution monitor
System Pictures : STV Mother Board - Lot of Carts - Unit - One Cart - Video Board - STV Manual
Notes : The STV system is based on the Saturn Sega's home console with different control maps, and there were 2 versions, the Japanese one (most common) and the USA one, which wasnt very popular.
They each had their own bios's and would mostly only play their own regions cartridges, I have listed where possible the compatibilities of each game.
Odd stuff : The manufacturer of the American STV-Titan dedicated cabinets (which were plastic) was mainly a manufacturer of waste storage containers, molded plastic stuff and whatnot. Turned out prescient as that's pretty much how the market received them; as garbage cans.
Emulators : MAME (Preliminary) - Satourne (Preliminary)
This hardware is based on Sega Saturn
