I don't have a steady one I take all the time. They change.
Last road trip I was on, I played Blaster Master Boy and Mega Man V for almost the entire time. I beat them both, although that's something I had done to each before.
On my one and only plane trip, I played Blaster Master: Enemy Below almost the entire time (both ways on the plane, and on a bus). Got to the fire area when the trip ended. I had to complete the rest of the game at home.
I'm going on a road trip on Wednesday. I'm probably taking Castlevania: Circle of the Moon and Final Fantasy: Dawn of Souls.

Where are these lemmings going? The
Super Nintendo Super Shire! Hop in line and follow them there!
