Games that do not work with systems.

[Atari Dogs]

I recently added the a/v mod to a spare light sixer i have.  I have not tried too many games on it, but one will not work.  Double Dunk will not start at all.  It does work on my 7800.  Should it work on a light sixer?  Did the mod do something?  Are there other games that will not work?  Are there certain 2600 games that don't work on certain 2600 modles?
