Unlike modern games that save to "My Documents," Yume 2kki (being an RPG Maker 2000/2003 game) saves directly inside its own installation folder.

File Extension: .lsd Naming Convention: Save01.lsd, Save02.lsd, etc. (up to Save15.lsd usually).

In conventional games, the map is provided. In Yume 2kki, the save file is the map. Players maintain multiple save files not merely for backup, but as a personal atlas:

The Yume 2kki community on wikis and Discord exchanges .lsd files (the RPG Maker 2000 save extension) as if trading coordinates. One player’s save file becomes another’s shortcut, turning private progress into public infrastructure.

Installing a downloaded save incorrectly can brick your entire game folder. Follow this manual process carefully.
