yeah, now i found that there are for PC two versions, identical to each other: Daytona USA and Daytona Deluxe. the only diference that i found is the menu and the GAME OVER screen.
USA uses a menu that is like the first saturn version while the Deluxe uses a red background menu. Also the options are different (USA:arcade mode,pc mode, options, exit DX: single player,vs,multiplayer,records,exit)
Game over screen in USA, the letter while moving, does effect like scaling and rotating, while in Deluxe, they are static moving characters.
