    I was wondering about how to compress images back into rle compression. I used DSDecmp.exe to decompress the images, but now I am wondering how to compress them.

    Thanks

    Thanks for your help.

    Edit: It was just images, but it seems that the compression was lz77 (like cmp files in the Etrian Odyssey Franchise).

    Phoenix Wright for example. If you played 5 case then you should remember Blue Badger and its dance - it's stored as RLE images, not a video.
    That's just an example. Many games on DS uses RLE compression.

    Thanks Vampires, I have seen it quite a few times on older systems and the gba but the DS is usually all about bitpacking, LZ (with a few variations) and huffman.

    I remember the big green rectangles in the scenario menu was compressed in RLE too... I think.
