Has anyone tried this? What does the picture looks like compared to a sdtv?
It is doable,
But old arcade screens cant handle the signals put out by modern things. Modern ones have newer type screens (dur)
but to be perfectly honest you would be better off taking the screen out and putting in a TV or VGA monitor as there will be lots of messing about getting it to work.
Had the idea a few years back to make a Wii arcade machine for all the shooters on it
