I like that feature too. The second slot is really something that is useful. The only thing that's a little bit sad is that the DS doesn't play Gameboy and Gameboy Color games. I know they are old etc. but the Gameboy Advance played them all and the GBA had only ONE slot. Means they could have build that in too... Well I guess it's not enough people wanting that feature.

Now to play my old games I need to power on the old GBA Smiley

PS: I still have my old Gameboy (the first one) in my room. Should I try to give him new batteries and play Super Mario Land 1?
