Games typically use compression algorithms akin to the LZ* family, or ones that offer similarly fast decompression, some type of huffman encoding, etc. The key to games is that decompression needs to be fast, but compression doesn't. Currently I am using LZ4 compression because it has insanely fast decompression rates, high compression, and is open source. I seriously doubt Nintendos OOT compression could beat it.
