after having a good list of games (thanks guys), i might need an expansion pak. i did a search and found an informative post regarding games that benefit from the expansion pak. i have a similar question. do games that are not specifically designed with use of the expansion pak (mario kart 64) benefit? i'm not looking for an increase in resolution (though it would be nice), but would the system overall run faster? when playing this game in battle mode with 4 players, everything is a lot slower. though i'll probably get one down the road for a separate game, i'd just like to know if system speed will increase with the pak. thanks in advance.
