Sega Saturn start-up collection...

Sega Saturn had 2 sibling models, Hi-Saturn from Hitachi and V-Saturn from Victor JVC both manufacturers were affiliated with Sega to support developing the console. Basically, both models were almost the same to original one except some additional functions like Video & Photo CD player with Hi-Saturn as upgrade model. 

Why did those OEM models were generated and supplied to affiliated manufactures? Because they wanted to sell the products in electronic shops which did not mainly deal with gaming gadgets so much in 90's. Sega Saturn was mainly sold in toy shops or gaming shops. However, sibling ones were retailed as electronical appliance or multimedia player for the purpose of expanding the shares against the rivals like Nintendo & Sony. 

The openings of the each model were different. Although V-Saturn and original one was almost the same animated movie except the different logos, Hi-Saturn had alternative one that contained some 3D logos on the cosmic wallpaper.
