i found the pictures in gamespot. http://www.gamespot.com/gba/rpg/hamtaro/screenindex.html if you found any pictures of Rainbow Rescue just post the link here.

wow...those pics are really cool!
by the looks of the pictures, the guy in blue would be the bad guy, i think.....

The goal in the game is to pretty much collect items that are the color of the rainbow. Niji Hamu, the guy in the blue, has an umbrella to help him travel, but the problem is, his umbrella lost its colors. He can't move on without the umbrella. So you set out to find stuff to give it back its color. The Ham-chat in the game is automated, and is not the emphasis of the game anymore. The game consists of mostly mini-games. How do I know? Well, wait a few weeks. I might release the rom on my site.

MUST....GET....RAINBOW....RESCUE..... =0........

Yeah, too bad ya don't got GBA.

All I would like to know is if it has Sabu in it =P

I read about it in Nintendo Power

The rom is now available on my site. Check it out if you are curious.

Wow, I grabbed the rom. And your site looks very nice I think I've been there before. The game is really different feeling. I love the portraits of the hamsters. I can read most of what the hamsters are saying so far in japanese since they're just talking about how beautiful the rainbow is...

The reason why it feels different is because this game wasnt made by the people that did ham hams unite and ham ham heartbreak. I can kinda tell they didnt spend too much time on this. It is amusing, and I like the direction they went with having mostly mini games.

Oh, a different company made the game; that would explain it. It's not as well done, in terms of things like sound effects and flow of events but it's colorful, cute and enjoyable. I was getting tired of ham-chat anyhow, the minigames will be a nice change :) That is, if I ever finish HHHB and have enough time to start Rainbow Rescue.
