Today I would like to show you a new tool (a remake of an old tool).
The tool in question is called GBA LZ77 COMPRESSOR. Here are some screen:
As you can see I decided to make everything a little more "clean" without bars indicating the conversion or the size to select.
This tool in fact, contrary to the previous, have an algorithm (I still have to finish writing) that allows you to compress all the images of all sizes (not more to 240x160).
Also has a Palette Viewer and a Tile Viewer :)
If you have suggestions, concerns, please write in the comments ^^
