1.3/2.0 ROM Cards
My preference for now is to be compatible with both. For one thing, I still
have some unused/unopened games that are vintage '86-87. You don't tire of
them if you haven't played them! I spend a lot of time in front of a
computer screen (programming for a living), and find that games aren't as
appealing at the end of a long day's work. But, I'm determined to get to
them all eventually! Plus, I have some other non-game products that have
not been updated in recent years.
