Guys. I have narrowed my colecovsion fault down to the BIOS. I borrowed a friends BIOS and my console works with his in it and does not with mine (and visa versa). I'd like to download and write a new bios for mine but need a dummies guide (and equipment needed). I like to play with this sort of thing so I am up for the challange! Any help, links etc etc are most welcome ?
