I have seen The Terminator listed (from several different sources) as being incompatible with the Sega CDX, along with Jurassic Park and a couple of games that nobody plays or cares about (Who Shot Johnny Rock? Who gives a fuck?).
Well, it works just fine on my CDX.
But! It doesn't work so well on my standard Model 2 Sega CD. It boots okay, but it's very prone to freezing. So prone that I have never been able to finish the first level without it freezing, and I've tried at least 10 times.
So... anybody else tried The Terminator on different Sega CD models? I would assume that it works fine on a Model 1 (after all, that was the only model in existence when it was developed). I haven't yet tried it on my X'Eye, which is packed away at the moment.
