I don't think the installer even worked for VC++ 6 on Windows 7. I also do not think that VC 6 is available from MS. VB6 is and will install and operate ok but I think that is the only component of VS 6 that is said to work.

btw there would be a very big difference between a NES emulator that can play a few rom games and a Windows emulator that can run under a Mac OS and allow VB6 to operate fully and correctly. Of course if you wanted to use a Mac you could just install Windows on it and be done with it at that point what you would have is an over priced PC running Windows
