The Sega Titan Video Game System (ST-V for short) is an arcade system board released in 1995.

DetailsEdit

The ST-V is an arcade system board, but unlike the previous boards based on custom specs, it is based on the hardware specs of the Sega Saturn home console. However, the ST-V used ROM cartridges for its software titles instead of CD-ROMs.

A majority of the ST-V's software titles were exclusive to Japan, but a notable exception was Dynamite Deka, which was brought overseas into North America as Die Hard Arcade. Because of the shared hardware specs between the ST-V and the Saturn, very accurate ports of ST-V titles were released on the Saturn.

Radiant SilvergunEdit

Radiant Silvergun was first released on the ST-V hardware, prior to the release of the Saturn version. It is playable on both the Japanese and U.S. BIOS.

Regional DifferencesEdit

  • When played on the Japanese BIOS, the game had a brief tutorial stage on how to use the weapons with the three-button control scheme. On the U.S. BIOS, however, the game uses a simplified two-button control scheme.

TriviaEdit

  • Presumably, it is named after the moon Titan, a satellite of Saturn, which the Sega Saturn was named after.
  • The manufacturer for the American dedicated ST-V cabinets (which were made of plastic) was primarily a producer of waste storage containers and other molded plastic products.
