... Well I don't do much Win32 C++ with VC++ (a Borland C++ Builder 5 user here, gotta love the VB-like form junk), but it looks to me that there are no command line args when 1964 PR2 is compared to the PJ64 source. Am I right?
... I don't think it would be hard to add command line args that would open a rom given its name/path. Too bad Win32 C++ isn't as easy as C under DOS.
