A 1200 set to a suitable screenmode (productivity or doublepal/ntsc) with the vga only monitor driver will work, and there's a handful of games that work in VGA mode, but the majority will not.
Games I've gotten to work either because they support it natively or through modepro or similar apps are:
Eye of the beholder 1 and 2, Warlords, Civilization, the SIM games, Onescapee, Nemac IV, Gloom deluxe, Genetic Species, Total chaos AGA, ScummVM, Subwar 2050 and a few others.
