I am now the proud owner of a Master Gear converter, so now I can play my SMS games on it, but I have a question about doing so.

On the box it says that you can't use Light Phaser, 3-D, or Sports Pad games with it. I assume that it's because they use peripherals that can't be connected to it, but what does happen if you try to play them?

Also, I've seen that some games are listed as being 50Hz (PAL standard), does that make a difference to the Game Gear?
