Nintendo R4 Card.

The Nintendo DS on its own is a fantastic gaming systems. But add an R4 DS Card to the mix, and a whole slew of homebrew programmers, and you have a handheld console.

1. Warhawk DS – Classic Shooter

Warhawk DS is based on a much earlier game released on the C64 in 1986, and is more of a re-imagining than a remake. One thing that was intended to retain was the 'old school' feel to the game, and this is hopefully something has been achieved. Do you like old school style shoot em up games? Then that's all I need to say about this one. It is truly an amazing and must have addition. The downside to keeping the feel is that those of you brought up on present day games may find this a little difficult? It is not an easy ride to clear the 16 levels, though a consession has been made for the modern-day gamer in the addition of continues.

2. Gbubies Planet

Glubies Planet is a mix between action and reflexion. The principle is simple, in each level a defined number of glubies must reach the exit. So you have to cross the level, find some objects and avoid the traps. The reflexion phase allows you to analyse the level, to drop and oriant objects et solve puzzles and enigmas. No time for thinking during the action phase.

3. GameUp – A Homebrew game updater.

While not a game in the full sense of the word, in any way. But Gameup deserves to be here on this list, simply because it allows you to find the best and most up to date Nintendo DS homebrew games online. So in essence, a must have for anyone that wants to grab the latest homebrew Nintendo DS game for their R4 DS.

4. Crack Attack

The best pc puzzle game now on the DS! Swap and flip blocks to match up their colors and make the disappear. One of my personal favorite games on the PC (and it was free and open source on the PC as well). If you're into puzzle games, and don't mind getting addicted to one, then Crack Attack is a must have for your R4 DS Card.

5. Marble DS Marble is a complete remake of the classic wood labyrinth game, in full 3D (both screen) with realistic physics, mp3 music, on-DS visual level editor and more.
