Not sure what the official procedure is, but these two movies need to be combined - they are identical.

Don't combine them! That are two different movies. I have both of them on DVD.

Very interesting. Have you watched Deadly Kick yet? Is it a "part 2" of Deadly Roulette?

I watched "Deadly Kick", but not "Deadly Roulette" (I only took a look in the movie). I don't know if the two movies have related stories.
"Kick" is available at a few DVD box sets of Brentwood Home Video (USA).
