Brunni has posted an excellent new application for the GBA and an entry into the Neoflash Coding Comp, heres the release details:
GBA Graphics is an easy-to-use graphical tool to convert any graphic (BMP, PNG, TIF, JPG, GIF) for your Game Boy Advance and use it in your project. It has a lot of options and is fast.
GBA Graphics also has a very powerful universal map editor, very easy to use, so that you will not have to create your own editor for your projects. It allows you to edit multiple maps (planes), link them, create specimen (sample) maps where you can pick up blocks easily, has multiple undo/redo support, displaying transparent planes, a properties window (set each tile individually), you can do arithmetic operations on tiles, zoom, define a grid, do parallax scrolling between planes, and much more. Look at "Sonic" in the "Example" folder, just open "Niveau 01.pgg" with GBA Graphics, you'll see, all is set-up to create sonic levels very easily and quickly, like you could do for any other 2D-type game. Even graphic conversions are automatized with script.
