Hello.
Flicker fixer is a "deinterlacer", or sort of.
Scan doubler is a.. well scan doubler. It doubles the scan rate of amiga graphics from 15kHZ to 31kHZ. Making it work on a standard PC monitor. However, using a LCD display. is a whole other story. Ask some of the other guys, they know that better than i do...
But if you plan on buying a SD/FF be prepared to dig deep in your wallet. They do not come cheap and are rare. They do pop up on ebay from time to time...
