Will there be a new SDK for CS6 PSX?
I have a number of plugins that I made using VS2005 VC++ for x32 and would like to now move them to x64. Should I still use VS2005 VC++ or use VS2008 or VS2010 VC++Express for CS6?
Yes. Pages are up to date as of today.
I have not tried 2010 Express but it should work. I don't think 2005 had much support for making 64 bit code but I could be wrong. We used 2008 for CS5 so that should work as well (not sure about Express).
