If they wanted to do it they would have given Tony all the details they have about the PPC classic HW and not have let him do reverse engineering IMHO.

Maybe they received the information under NDA or similar? Maybe Toni hasn't asked for the information because he wants to reverse engineer it for himself. Considering how pointless the BPPC and CSPPC turned out to be I suspect trying to emulate them is just for the lolz and not really a serious effort to reach 100% perfect emulation.
I'm not sure why some of you guys always need to make someone out as the hero and everyone else (even if they aren't remotely involved) as the bad guys(TM).
