Hi, I'm a newbie here, but I've looked all over the web to find this and have so far found nothing - does anyone have instructions about how to add a 50/60Hz switch (& a language switch too while you're at it...) to a Sega Genesis 3? Is it even possible? I assume it's just a case of the usual JP3 & 4 switch, but according to this site the Genesis 2 needed another trace cut for whatever reason. Please help!!!
