I was about halfway through Phantom Hourglass when my DS Lite broke, and now I'm waiting on a DSi to replace it (I'm going to be MUCH more careful with it).
I'm almost done with Final Fantasy: Crystal Chronicles: The Crystal Bearers, but I've been stuck on the final boss for weeks. I only started making progress when I had my Mom start holding the nunchuck so she can dodge Jegran's Arm while I aim for it with the Wiimote, but I've never been able to make it past the part with the four batteries. I'm in the process of looking up items that increase my attack and defense, and it's not going well because there are no good FAQs for the game. I'm having to figure out a lot of things through trial and error, and it sucks.
I've recently started on Ocarina of Time: Master Quest. I had never planned to play it, as I'm not a challenge seeker. It's mainly because I didn't finish OoT last month when I started a new game, and didn't feel like going back to my old one in the middle of it... but also didn't feel like doing the same three starting dungeons for the tenth time (I have a really bad habit of quitting soon after I get the Master Sword). So I'm playing MQ in order to solve both problems. Not to mention giving me something to do while I wait on my new DSi and Metroid Prime 3 to come. The Deku Tree is a LOT harder now, though... the most annoying part was those Fire Keese burning up my Deku Shields. I almost died once, and certainly ended up using those recovery heart plants... I have a feeling that Blue Potion shop will be seeing a lot of my business soon.
