They've made an auto-extractible 1st_read.bin, and so, no code can be found (unless you know how to decompress it, find the code, recompress it, and finally make a patch). The intro messes up with RGB cable.
There's no patch available, but there's something to do : use the original 1st_read.bin with no intro.
