Ps2 katana wireless controller pcb hack?

hi, just wondering if any vets have tried of maybe heard of doing a pcb hack with this wireless katana controller pcb. thanks!

well I found an extra controller for cheap, so I suppose ill try and see if I can get it to work and post the results here. hoping for the best, the wireless katana works lagless with my ps3/DC/sega Saturn/360 converters like a champ, would be awesome to pretty much have a wireless stick for all my systems! will update later
