FC Twin Compatibility

[IIICCCPIII]

So I got an FC Twin a long time ago and I just started using it, and wouldn't you know, I already have two games that don't work on it. The B button on ducktales doesn't work, and Castlevania 2: Simon's Quest do not work. Wiki says Castlevania 3 doesn't work, but they didn't say anything about Castlevania 2. So are there any games that the list on wikipedia missed? Do any of you guys have a black fc twin, and if so, does it play unlicensed games? For example, I'm planning on getting Tetris Tengen for NES, should i, or will it no play on an FC twin?

Here's the wiki list of incompatible NES games

I have an FC Twin.

Castlevania 2 does not work. Airwolf, and Battletoads however does work on my FC Twin. There have been multiple revisions of the FC Twin so keep that in mind. If your FC Twin logo is "jeweled" you have a "newer" model which has a bit better compatibility and all the sound issues are pretty much solved.
