Coding > About Gba Compression

#36231 - mentz - Wed Feb 16, 2005 8:41 am

Is there a program that could compress and decompress data using gba bios compression ? (lz77,Huffman,RLE)

It will be nice to know even the header of compressed data
(with huffman and rle. Lz77 header is alredy well described in another thread)

Thank to all...

the headers are described in gbatek, you can use GBACrusher to compress your files.

As far as I know, all the GBA compression headers start out the same: decompressed length in upper 24 bits and compression type in lower 8 bits.
