Compatibility information is now (Project64 v1.4+) provided by the ROM Browser, please refer to that for details of every game. There were a few mistakes in the RDB included with v1.4, which are being corrected as far as possible in the updated RDB releases (under Support/INI files).

If you want to look up the compatibility of any game, I suggest you open the latest RDB in Notepad, search for the game in question, and read the Status and Notes fields. This will probably give you the most reliable indicator of compatibility available.
