MD: Red Rescue Team(lost)
Sapphire(own)
MD: Explorers of Time(lost)

Soul Silver(lost)
White(lost)

Well here's the ones I own and a little info and stuff I did..

Pokemon Fire Red - I played over 250 hours of this game and this is the game I caught the most Pokemon on. I had so many frustrating moments in this game.. :3

Pokemon Sapphire - I've hadn't played this game in 6 years so that's the fun fact. :3

Pokemon Ruby - Hadn't spent the most time on it, only passed the 8th gym though.. :/
  
Pokemon Emerald -  Spent about 50 hours on this one. I caught most Pokemans.

And the others:

Pokemon HeartGold
Pokemon SoulSilver
Pokemon Diamond
Pokemon Pearl
Pokemon Platinum
Pokemon White
Pokemon White 2
Pokemon Y.

There are some others I think but I forgot them. I have so many Pokemon games...

Pokemon Yellow: This was the latest Pokemon game I got, as in by date I got it. I haven't beat it but I am at the elite 4 saved at the champion.

Pokemon Silver: I got this one after I got soul silver and boy the original was so much better. You don't have to sit through all of the battle animations and even with them off the battles are faster.

Pokemon Ruby: Meh... I got this after Emerald and found there was very little difference, I only put about 2 hours into it.

Pokemon Emerald: This was my first game I brought with my own money. On my first profile before I deleted it I had a total of 360 hours wasted on it. I had all of the pokemon you could catch in the game without events and all of the frontier badges.

Pokemon Soul Silver: It is a good game but it is not as good as the original. I had a great team on it though until I started again to race my friend.

Games I had...

Fire Red - I only borrowed it
Platinum - I hated it and sold it
Black - Same story
Pokemon X - I borrowed it and hated it!!
