That wouldn't help. It would probably break the program, especially if the
program in question was an arcade game.

European TVs work at 50 Hz. We make up for the fewer frames per second by
having more vertical resolution and properly-encoded colours. One of the
things which amazed me about US TV on visiting the US was that it really was
as bad as it looks over here. I had always assumed that it looked all
blurry and smeared because of some defect in the NTSC->PAL conversion.
It really spoilt "Cheers" when they went from film to grotty US video.

The only solution to your problem is to get a better TV, I'm afraid. My Sony
works at either 50 or 60 Hz. I gather that Atari monitors work at either
speed, as well... and of course, a multisync will handle it with no trouble.
