Wow, after looking at what my collection was a few months ago, I'm surprised to see how much it has grown recently. Anyways, here is what I have now.

My main list

Brave Fencer Musashi (PS1)

Okay, I've never got to play this other than the demo at a friends house, but this can work on the DS.

Dino Crisis (PS1)
Again. If they ported RE1 onto the DS, they do Dino Crisis too.

Mario Allstars

It doesn't have to be like the SNES one. It could just be ports of the Mario land games, and maybe the Wario land games too.

No, they cannot. You guys need your own cart to play the tank battles.

However, you can send a demo of the tank battles to your friends' DS.

I carry them in that library thing.

Although I don't always bring all my games, because I don't have a good case that would hold my (growing) collection, so I keep them in their game cases.

I would try and make an action/adventure/RPG type 3D game, similar to The Legend of Zelda.

I would use the touch screen for certain puzzles and other interesting stuff, like control, weapons, and maybe even boss battles and minigames.

Games are region free.

I have 8 Japanese DS games,and they all work on both of my american DS', Phat and Lite.

Also, does your buddy know to bring a power converter?

I use my shirt.rjs927

Same, and an Eyeglass cleaning cloth.

All are 2 years worth of games.
