Try a soft reboot before playing to see if that helps. Also be sure you have enough free program memory and a little free storage memory to be safe.
Asteroids works , so that is a good sign that everything is setup and operational. Maybe try a different(older) romset.
I haven't tried any of the new .53 versions so maybe they have made a few changes.
