About once every couple of years we dig the SNES out to play Secret of Mana. Since the last time we have replaced our old CRT TV with a new LCD model.
Although the new TV cable had scart sockets as well as HDMI, it wouldn't work with RGB only composite (which looked horrible on a 42" screen). I found some websites explaining how to fix the problem with a soldering iron but buying this cable seemed like an easier option.
Sure enough it works a treat and we can now play Secret of Mana again with a true RGB connection.
In case anyone is interested, I also tried this cable with a Startech Scart to HDMI converter and that works with RGB as well.
The only word of warning I would add is that, as I have found, not all SNES RGB scart cables are the same. The one I bought (through Amazon) was supplied by Mega Mix UK but I note they are now offering it from a different supplier. It might be worth checking with the seller that it will work with LCD TVs prior to buying.
