I've been working on a DS-based level editor, and by now the basics are pretty much covered. Proudly presenting: My Tiled Map Level Editor for NDS! Download: http://temp.dennisva...LevelEditor.rar Screenie (kinda blurry; blame pasting in word, then copying from there): Levels can be up to ~500000 tiles in size (for reference, the original NES Mario world 1-1 is ~4096 tiles in size). This number is limited by the DS' memory only (4MB yay). Updates Intermediate (111124): Fixed crash bug for AKAIO users. 111113: - Added autolog save (fat:/data/LevelEditor/console.log) on guru crash - Added custom level save location Current features: - Easy-to-use level editor with stylus controls - Simple but efficient UI - Generic level data format to be used in any game engine - Show or hide grid, tile IDs or complete layers - Level saving/loading to/from sd - Up to 5 layers (last layer reserved for collision map data) - Dynamic layer resizing (when possible, resizing will keep your level data in place) - Customizable Parallax layer scrolling - Built-in customizable playtest featuring Mario Known bugs: - Playtesting may have some frameskips with crowded levels - Layers may not display correctly with severely crowded levels Confirmed working: - R4 - Acekard 2i Readme/user manual included in zip (Level Editor User Manual.pdf). NES Mario world 1-1 included for funsies (Mario.level). Copy the 'data' folder in the zip to the root of your flashcart to use.
