This application for the PlayStation Portable (PSP) will definitely be a big help to all the other homebrew developers out there as LuMM is 2d tile map editor for lua games. It edits a map in three layers.

Notes for this version: * ground layer : the basic map area * object layer : assigns a number value to the current tile area 0 is not displayed in the editor. In my demo, I used 0 for walkable area and set 1 to indicated an impassable barrier * overlay layer : this layer is for images that the player can walk behind * saves / loads map info to a single data file * map edit mode: * start = brings up save/quit menu * d-pad = change current map location * square = put tile down * cross = erase tile * triangle/circle = cycle through tiles / object numbers * right trigger = cycle through layers * left trigger + d-pad left/right = change tile rotation (not implemented yet)
