Portable Adventure games

[alienjesus]

I've been getting into point 'n' click adventure games lately, I love the stories, the humour and the mind boggling puzzles. The only problem is I'm not a big fan of being constrained to my computer every time I want to play one. To me, they're perfect to dip in and out of, and for that reason, I was wondering what Adventure games are available on handheld systems.
Can anyone name any ? Here's some I thought of - some might be a stretch, but what the hey:

Nintendo DS:
Another Code/Trace Memory
Broken Sword
Ghost Trick
Hotel Dusk + Last Window
Phoenix Wright series
Professor Layton series
999

Game Boy Color:
Deja Vu I & II
The Fish Files
Scooby Doo: Classic Creep Capers

Any other good ones that come to mind?

Not sure which games in the series, but some of the Runaway adventure games have been ported to the NDS.

ScummVM runs on just about anything (Android, iOS, PSP, DS etc). They even have a Nintendo 64 version of the program, I wonder how that works
