the bridges in DW1 as you probably know mark different areas with different sets of enemies. each time you cross the bridge it banks in the sprites for that group of enemies on the fly.

The bridges in DQ1 split the map between different areas with different enemies, but it's more than that. When you go over a bridge, the game banks in the next set of enemy sprites. You can notice this since there's momentary slowdown going over bridges.

See the bridges? As you all probably know, these are divisions between different regions of the map that contain harder enemies. Whenever you cross the bridges, there's a momentary lag of about a frame or so. Why? Because it's switching the CHR bank to get the sprite data for the next set of enemies.

You can also notice something similar in Dragon Quest 1. The US version replaced the CNROM from the Famicom with an MMC1 to allow battery saving and there's definitely a noticeable pause when you go in and out of towns and dungeons as it's switching the banks for them. Also when you cross the bridges, there's momentary lag because it switches in the enemy data for that region of the map.

Can we get a world map/bird's-eye view thread going? I have a thing for these.
