This page lists the IDs for every map in the game, as well as the author who reserved them, the world it is associated with, and whether or not it is accessible or not.
Each map can be viewed in the editor by opening RPG Maker 2000 or RPG Maker 2003 and opening the "ゆめ２っき" folder which contains all of the game's assets, all of the map files, and et cetera with the "Open Project" function in the "Project" tab. From there, each map is open for selection in the column on the left. (it is important to note that almost all of the game's maps are sub-maps of other maps, and can only be viewed by clicking on the [+] on the side of each parent map)
A world labeled "Accessible" can be entered through normal game means without the use of editing the game. Maps labeled "Inaccessible", therefore, cannot be entered this way. However, there are some maps labeled "Unused", which means they have been reserved but no content has been added to them. Only maps labeled "Accessible" contribute to your map percentage (equal to the number of dreamdollars you get upon breaking open the piggy bank in Urotsuki's Room )
