Alias: Dark Messiah (as originally titled in Japan) for Hellnight

Rapid Racer (PAL) and Turbo Prop Racing (NTSC-U) are the same game.

The developer studio was Team Soho, and it was first released in Europe, so I'm recommending that Rapid Racer is the entry that should be kept, with Turbo Prop Racing as an alias within it.

Also, the official soundtrack composed by Apollo 440 is titled "Carrera Rapida (Theme From Rapid Racer)", so I guess Rapid Racer is the more official name for it.
