In my experience with messing with modes, mode 6 is the biggest cancer that make many games not work. The reason is that OPL has a in game reset plugin that's enabled by default, and if a game already has one natively, they conflict. It's safe to set Mode 6 to ON on all games, so it disables the opl plugin.

Yeah I know, it must be set to ON in order to disable it, OPL is retarded that way.
