I still dont think I get it u.u
I think the first one is where when you step forward in the game, then the bottom row disapears and a new top row appears... or something? Is that right?
and then I know there's games where you just walk around in a rectangle of map and when you reach an end [Top, Right, Bottom, or Left] it will take you one rectrangle of map over in that direction... I think this might be the type with Zelda games... if I remember correctly...
Do either of those make sense... and/or are either of them what you're talking about? x.x
