Wow, fortunately, almost EVERY game you just listed I have on my flashcard (if you like DS games, you should seriously look into getting one)
Also, there were a few games I played once or twice that were EFFIN AWESOME. I'll post them as soon as I get further into them.
And yeah, I must admit that at 1st, I thought DS sucked balls...Then, as time went on, the games it came out with grew steadily cooler and cooler...All the sudden, i realized that I had a DS and am missing almost 10 good games. Yes, it's my fav. handheld by FAR (and I'm an extreme GameGear fan, too) ever since I got my Firecard and actually got to play some of the awesome games that're out.
As for Yoshi...I think it paid nice respect to the SNES version in every way EXCEPT music. OMG. They fucking ruined that...But the game play is almost identical with new twists, so I love it.
Hotel Dusk: Room 215
That's one of those games that I just recently added and didn't get too much time to play, but it really does seem AWESOME so far, and I think worth getting. It looks like one of the most well done DS games (128 mb vs. all the other 64 mb games) I've seen ina long time, though I guess I can't fairly say too much--I've only played a few minutes into it.
Phoenix Wright: Ace Attorney
I have this, but since I've never heard of it, I didn't put it on my card. Is it any good? What type of game?
Also, Secret of Mana looks like a great game, you should give that a go or look into it.
Oh, and I'm planning on getting the Diddy Kong Racing remake soon, as I LOVED that game on n64.
