Like I said earlier, it doesn't work. It's the same as all the other hex patches that have come out in he past 24 hours. There is an issue that prevents bd_dev from being patched, even if the descriptors file is changed. I think the issue is that the packet size is so small that the bd_dev call gets split up and therefore doesn't execute. Nobody has figured this out yet. The original dv is looking into this while porting the new version of psgroove. I would expect some explanations of what's going wrong to appear by the end of this upcoming weekend.
