No, Silver doesn't have his own game.

There isn't one that is just Sonic the hedgehog 2, but there is the Sonic Classic Collection which has 1,2,3, and Sonic & Knuckles
There will always be a slight chance, but it's very unlikely.
There is no Super Mario Galaxy DS.
Neither game is real, the real game's name is Pokémon HeartGold and Pokémon SoulSilver. They are remakes of Pokémon Gold and Silver due to their 10th anniversary and they'll be for the Nintendo DS, DS Lite and DSi. In Japan they were released on September 12, 2009 and for North America the release date will be in the Spring of 2010.
it has to be a problem with your ds or your game. try replacing your game and if that doesn't work try getting your ds looked at gamestop
