Bumping this thread because I just remembered there was a Japan-exclusive PC port of the first Twisted Metal.

Beside minor graphical differences, the biggest change it does is that it replace Darkside's special with a freeze ray. This version is so insanely rare and obscure that most game database sites don't even list it.
