OK, I know last week was Genny week, but I just got my Genesis on Saturday.
Why do some cartridges have the yellow clip on them? Why are the cartridges different sizes? Do some of them have batteries in them, and if so, are they changeable? I have a couple of games that save information, and some that appear that they should, but don't... NHL95, NHL96, and NHL97 for example, only 96 saves info, the other two loose the info...
TIA!
