30$ Gift Card. Help choose a game.

I need your assistance in purchasing a great DS game with my 30$ gift card. It can either be a Wifi or non-Wifi game. Let me start off by stating that I am very picky when it comes to games for the DS. Since the DS tends to all audiences and I am but one audience member, I believe there are a lot of games that I'm just not interested in. I am willing to put in any extra money if the game's price exceeds 30$.

Please read before posting your reply:
-I am not a fan of Pokemon or Pokemon-related games, this includes most RPG's (Sonic Chronicles: The Dark Brotherhood).
-I own Final Fantasy 3 and have yet to beat it and decided that before I get FF4, I must finish 3.
-I currently own 18 games. Some of my favorites are: Electroplankton, Gunpey, Mario vs Donkey Kong 2, Tetris DS, Mario Kart, Space Invaders Extreme, New Super Mario Bros, Trauma Center, Warioware Touched, and Sonic Rush.
-I have both Brain Age games....boring.
-I will not buy Kirby Superstar Ultra since I own the original for SNES and I heard it's better.
-I have Geometry Wars for Wii and can play the basic game on my DS, I don't want the full version.
-I'm not a youngin' so "kiddie" games probably wouldn't appeal to me (but there have been exceptions (Disney Meteos)).

I know there are tons of great games for the DS that I have yet to discover. If you can provide me with your most zenith suggestion, I will research as so and get back to you when I have made my decision. Thank you for your time and your recommendations.

Someone please help me.

I apologize ahead of time if this has already been posted somewhere.

I've had the Homebrew Channel installed on my Wii for about 3 months now. When the last Wii System Update was announced, I read somewhere that it wouldn't affect the Homebrew Channel if installed. So I went to update my Wii but after roughly 12 seconds of the update process, I cancelled it because I got a bad feeling about it. I did some more research and discovered that there was a Homebrew Update and a Wii Shop update that was compatible with the Homebrew Channel. So I executed both of the new updates.

When I go into the Homebrew Channel, everything seems fine but two of the programs don't work anymore and instead they provide me with a "This is not a valid Wii application" message accompanied by a red symbol that appears to be an "X". Those two programs are two of my favorites, Ocarina (The cheating application) and FCE Ultra GX (not the updated one). I used these two apps the most out of anything on the Homebrew Channel. I redownloaded them and they still didn't work. I downloaded the updated version of FCEU, which works but doesn't satisfy me fully like the FCE Ultra GX. Oh well. I downloaded the Ocarina app as well to no avail. I really need this application.

Can anyone please help me with what I should do?
