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 only play their own regions cartridges, and as far as I know there was only a few of the games converted to the USA version...
Odd stuff : The manufacturer of the STV-Titan dedicated cabinets (plastic) was mainly a mnaufacturer 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 : Satourne (Preliminary)
This hardware is based on Sega Saturn
