[576, acutally, at full overscan, for PAL. don't know the figure for NTSC]

Seems like the best solution would be to write your game for (a virtual) 300Hz
display, and only display every 5th or 6th frame. Otherwise, to convert 60Hz
to 50Hz, you have to skip an update every 6th frame, which is likely to be
really gross.
