Skype 5-way Calling Limit Cracked

Posted by Xavier Ashe on March 5, 2006

“It turns out when Skype limited 10 way calling to Intel Processors only it really was arbitrary! Maxxus has a patched version
of Skype that allows 10-way calling regardless of the processor
installed. There's also info about the patch: “The patch is the result
of two phases: code analysis and design of the patch. The code
analysis, or reverse engineering, reveals the relevant code block,
which overrides Skype's limitation for Intel's dual-core CPUs. The
patch design isolates the minimal set of instructions that need to be
modified to cancel this limitation.” Windows only so far.”
