ROM Hack Rle compression

[matthewn4444]

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

If it is standard BIOS compatible compression then gbacrusher:
http://members.iinet.net.au/~freeaxs/gbacomp/#GBA%20Crusher (it appears to also be on http://www.bargaintuan.com/gba/ if the first site is being slow).

I have to ask though what game uses RLE; I am not sure if I have encountered anything on the DS that uses it.

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.
