Changing the frequency of games to sync to movie cameras...

Film cameras work at 24 frames/second, whereas video games are
30/second. I should be able to change the clock crystal to reduce the
speed to 24 frames, but will the game play speed seem that much slower -
I suspect it will.

I was also planning on providing a sync output line for the camera guys
to use to lock on to the game.

A game needed to try this on is Super Mario Bros.

Can the monitor adjust down enough to still show a picture without rolling?

The horizontal frequency will also shift downwards of course... 24:30 =
5/6ths as fast - about 1300kHz

Any other bright ideas?

Thanks,

John :-#)#
